The Jendrassik maneuver is sometimes used when a subject needs to be distracted, and usually results in a larger reflex test response. Was this true for you? Explain what happened

Answers

Answer 1

he JM will heighten (exaggerate) lower limb tendon reflexes by countering some of the normal descending inhibition the brain sends to the reflex arc.

What happens during the Jendrassik maneuver?

A medical technique called the Jendrassik manoeuvre involves the patient clenching their teeth, flexing both sets of fingers into a hook-like shape, and interlocking those sets of fingers. The patellar reflex is then induced by striking the tendon below the patient's knee with a reflex hammer.

When the technique is not being used, the reflex outcome of the same movement is compared to the induced reaction. When a patient is focused on the technique, a bigger reflex reaction is frequently seen: "Afferent activity brought on by such muscle tension may activate a weak or seemingly absent reflex.

This is the actual justification for the procedure, not that it is intended to divert the patient's attention, a common misperception that persists to this day." This result

A car and a truck move on the road in the same direction at the same
speed. Both vehicles slow down with the same stopping force.
Which statement best explains why the truck needs to more time to stop?

Answers

Answer:

The statements are not given, so I will answer in a general way.

We know that when one object is moving with a velocity V, and it wants to come to stop, it needs to accelerate in the opposite direction to the initial velocity (Or decelerate).

As larger this acceleration is, the faster the object will come to a full stop.

Now we have a car (with a mass m) and a truck (with a mass M) are moving with a velocity V.

We can assume that the mass of the truck is larger than the mass of the car, then:

M > m.

Now also remember Newton's second law:

F = m*a

Force equals mass times acceleration.

And we know that both vehicles stop with the same stopping force.

Then the acceleration (deceleration actually) that experiences the car is:

a = F/m

While the acceleration that experiences the truck is:

a' = F/M

Because M is larger than m, we will have:

a' < a

Then the deceleration of the truck is smaller than the one of the car, which means that the car will come to a full stop faster than the truck (or the truck needs more time to stop)

The total force acting on the system is equal to the acceleration of the center of mass multiplied by the total mass of the system. When applied to an extended object, Newton's second law, F = ma, predicts the motion of a specific reference point for this object. The center of mass is the name given to this reference point.

When we throw an object upward, gravity acts on it, and the acceleration it experiences is the inverse of the acceleration caused by gravity, i.e. deceleration. As a result, the acceleration of each ball will be g. As a result, the acceleration of the center of mass of the two balls thrown upward is g.

how much time would it take for an object to fall 4.7 meters

Answers

Answer:

t = 0.97 s

Explanation:

Given that,

We need to find the time taken by the object to fall 4.7 m.

Let it is t. Using second equation of kinematics to solve it such that,

[tex]h=ut+\dfrac{1}{2}gt^2[/tex]

u is initial velocity, u = 0

So,

[tex]h=\dfrac{1}{2}gt^2\\\\t=\sqrt{\dfrac{2h}{g}}\\\\t=\sqrt{\dfrac{2\times 4.7}{9.8}}\\\\t=0.97\ s[/tex]

So, the required time is equal to 0.97 seconds.

The time it would take the object is 0.98 secs

From the question,

We are to determine how much time it would take for an object to fall 4.7 meters. That is, the time it would take the object to fall from a height 4.7 meters.

From one of the equations of motions for free falling object.

[tex]h = ut + \frac{1}{2} gt^{2}[/tex]

Where h is the height

u is the initial velocity

t is the time

and g is the acceleration due to gravity (Take g = 9.8 m/s²)

Since, the object is dropped from rest, the initial velocity, u, is 0 m/s

From the given information,

h = 4.7 m

Putting the parameters into the equation, we get

[tex]4.7 = 0(t) +\frac{1}{2} (9.8)t^{2}[/tex]

[tex]4.7 = 0 + 4.9t^{2}[/tex]

[tex]4.7 = 4.9t^{2}[/tex]

∴ [tex]t^{2} = \frac{4.7}{4.9}[/tex]

[tex]t^{2}= 0.9592[/tex]

What is radioactive decay?

Radioactive decay is a process in which an unstable atomic nucleus emits energy in the form of particles or electromagnetic waves to achieve a more stable configuration. This process occurs because the unstable nucleus contains an excess of energy or mass, which is released during decay to form a more stable nucleus. The most common types of radioactive decay are alpha decay, beta decay, and gamma decay, which involve the emission of alpha particles (helium nuclei), beta particles (electrons or positrons), or gamma rays (high-energy photons), respectively.

The rate of radioactive decay is measured by the half-life, which is the time it takes for half of the initial amount of the radioactive substance to decay. Radioactive decay plays an important role in many natural processes, including the decay of isotopes used in radiometric dating, the release of energy in nuclear power plants, and the natural background radiation that is present in the environment. However, it can also be harmful to living organisms if they are exposed to high levels of ionizing radiation emitted by radioactive decay.

Here in the Question,

Option A is not true because nuclei with a mass less than that of an iron nucleus (A = 56) are generally unstable and can undergo radioactive decay.

Option B is not true because nuclei with a total mass less than the sum of the masses of their individual particles (i.e., mass defect) can still be stable, such as helium-4.

Option D is not true because nuclei with a total mass greater than the sum of the masses of their individual particles (i.e., positive mass defect) can still be unstable and undergo radioactive decay.

Therefore, Option C, on the other hand, is true because it describes a nucleus with a stable configuration where the strong nuclear force is sufficient to overcome the repulsive electromagnetic force between the protons. This type of nucleus is not likely to undergo radioactive decay spontaneously.

find the rise in temperature when given: 1.original length(2.0m),2.linear expansivity(25),3.increase in length(3.0mm)​

Answers

According to the answer the rise in temperature is 0.12K..

What is temperature?

Temperature is a measure of the average kinetic energy of particles within a substance. It is measured in degrees on a wide range of scales such as Celsius, Fahrenheit, and Kelvin. Temperature is an important indicator of a material’s state and behaviour, as it influences the rate of chemical reactions and the physical properties of materials. Temperature also affects the flow of heat and the direction of heat transfer. For example, heat flows from hot to cold, and cold air will sink while warm air will rise. Temperature is also used to measure the average kinetic energy of molecules in a gas, which ultimately determines its pressure and volume. Temperature is an important environmental variable, as it affects the Earth’s climate and weather.

The rise in temperature can be found using the formula for linear expansivity, which states that the change in length is equal to the linear expansivity multiplied by the change in temperature.
Change in length(ΔL) = Linear expansivity(α) × Change in temperature (ΔT)
Therefore,
3.0mm = 25 × ΔT
ΔT = 3.0mm/25
ΔT = 0.12K

Calculation:

The following formula was used to determine the frequency:

radio wave speed, c = radio wave frequency / radio wave length

c = f x λ

Because a radio wave is an electromagnetic wave and travels at the same speed as light, its speed, c = 3 x 108 m/s, is equal to the speed of light in this case.

When the formula

3 x 108= f x 1.0

Finish A 16 N force is applied to an object and 96 J of work is done. How far was the object moved?

Answers

Answer:

[tex]\boxed {\boxed {\sf 6 \ meters}}[/tex]

Explanation:

Work is the product of force and distance.

[tex]W=F*d[/tex]

We know that 96 Joules of work were done and a 16 Newton force was applied to the object.

W= 96 J F= 16 N

Substitute the values into the formula.

[tex]96 \ J= 16 \ N * d[/tex]

First, let's convert the units. This will make cancelling units easier later in the problem. 1 Joule (J) is equal to 1 Newton meter (N*m), so the work of 96 Joules equals 96 Newton meters.

[tex]96 \ N*m= 16 \ N * d[/tex]

Now, solve for distance by isolating the variable, d. It is being multiplied by 16 Newtons and the inverse of multiplication is division. Divide both sides of the equation by 16 N.

[tex]\frac {96 \ N*m}{16 \ N}= \frac{16 \ N *d}{16 \ N}[/tex]

Answers

The mass of the twig can be calculated using the law of conservation of momentum.

What is law of conservation?

The Law of Conservation states that matter and energy cannot be created or destroyed, only changed from one form to another. This law is one of the most fundamental laws of physics, and it applies to all forms of energy, including heat, light, and electrical energy. This law helps explain why energy is always conserved, meaning that it can never be lost, only transferred or converted into another form. This law is also important in understanding the behavior of matter, as it explains why matter can never be completely destroyed, only rearranged or changed in form.

Momentum is equal to the mass times the velocity, so the total momentum of the twig and the snail before the snail starts moving is zero. After the snail starts moving, the momentum of the twig and the snail is equal to the snail's momentum, which is equal to 2.5 g x 1.2 cm/s = 3.0 g cm/s. Since the velocity of the twig is 0.4 cm/s, the mass of the twig must be equal to 3.0 g cm/s / 0.4 cm/s = 7.5 g.

10. A banana has a mass of 183g, when the apple is at a height of 2.8 m on an unknown planet, theapply has a GPE of 250 J. what is the value of gravity on the unknown planet?

Answers

Question 8. The mass of the object is approximately 36.091 grams.

Explanation for question 8. The formula for gravitational potential energy is given by:

GPE = mgh

where GPE is the gravitational potential energy, m is the mass of the object, g is the acceleration due to gravity, and h is the height to which the object was lifted.

We can rearrange the formula to solve for m:

m = GPE / (gh)

Plugging in the values given, we have:

m = 4321 J / (9.8 m/s^2 * 1234 cm)

Converting the height to meters and expressing the mass in grams, we get:

m = 4321 J / (9.8 m/s^2 * 12.34 m) = 4321 J / 119.852 m^2/s^2 = 36.091 grams

Therefore, the mass of the object is approximately 36.091 grams.

Question 9. The value of gravity on the unknown planet is approximately 15.16 m/s^2.

Explanation for question 9. The gravitational potential energy of an object is given by the equation:

GPE = mass * gravity * height

Rearranging this equation to solve for gravity, we get:

gravity = GPE / (mass * height)

Plugging in the values you provided, we get:

gravity = 190 J / (150 g * 1.9 m)

Converting the mass to kilograms (150 g = 0.15 kg) and performing the calculation, we find that the value of gravity on the unknown planet is approximately 15.16 m/s^2.

Question 10. The value of gravity on the unknown planet is approximately 10.3 m/s^2.


Explanation for question 10. In order to find the value of gravity on the unknown planet, you need to use the formula for gravitational potential energy (GPE), which is:

GPE = mass * gravity * height

You can rearrange this formula to solve for gravity:

gravity = GPE / (mass * height)

Plugging in the values you provided, you get:

gravity = 250 J / (183 g * 2.8 m)

Solving this equation, you find that the value of gravity on the unknown planet is approximately 10.3 m/s^2.



A box is released from the top of a frictionless track. It starts from rest and has a speed of 14 m/s at the bottom. What is the height of the track

Answers

If we use the aceleration equation, we can calculate the height value: The height of the track is: 98.04 m,

The height of the track can be calculated using the equation:

h = (v^2)/(2g)

Where h is the height, v is the velocity, and g is the acceleration due to gravity (9.8 m/s^2).

Therefore, the height of the track is:

h = (14^2)/(2*9.8) = 98.04 m

The equation h = (v^2)/(2g) is derived from the equation of motion for an object moving in a uniform gravitational field. This equation states that the change in potential energy is equal to the kinetic energy of an object. The potential energy of an object is determined by its height in the gravitational field, and the kinetic energy of an object is determined by its velocity. Therefore, the equation of motion can be used to calculate the height of an object, given its velocity.

so far all ive got is Cu₂ +4P --> _____​

Answers

Answer: The answer is Cu+ P4 = Cu3P2

Which after balancing would be, 6Cu + P4 = 2Cu3p2

Explanation: Copper (Cu) is a metal and Phosphorous (P) is a non-metal. Metals and Non-metals combine to form ionic compounds where there is a transfer of ions from metal to non-metal.

Phosphorous has 5 valence electrons in its outer shell and Copper has 2 valence electrons. Following the octet rule, which means that the outer shell should have 8 electrons to be complete we see that combining these two metals on combining have electrons insufficient so we combine till we reach the octet structure. In this case, it happens when there are three copper and two phosphorous. We see that there are no more valence electrons. So it forms Copper II Phosphide, where the two indicates the charge of Copper.

Then we move on to balance both the sides of the equation, upon placing one number after the other to make the numerical value of elements equivalent to the other. Which gives us the answer.

A 200-kg crate is pushed horizontally with a force of 720 N. If the coefficient of friction is 0.20, calculate the acceleration of the crate.

Answers

1.54 is the acceleration of the crate. The Second Newton's law states that an object acquires acceleration when an external unbalanced net force is applied to it.

Acceleration is proportional to the net force.

That acceleration is proportional to the net force and inversely proportional to the mass of the object. It can be expressed with the formula: Where, Fn = Net force, m  = mass. The m=200 kg crate is pushed horizontally with a force Fa=700 N. The friction force opposes the motion and a horizontal net force appears causing the acceleration.

Forces in the vertical direction?

The forces in the vertical direction are in balance since the crate does not accelerate in that direction, thus the weight and the normal force are equal: N = W = mg, The friction force can be calculated by using the coefficient of friction μ: μ*n. Calculating the normal force: N = 200 * 9.8 = 1,960 N. The friction force is f=0.2*1960, f=392. The horizontal net force is 308. Finally, the acceleration is computed: m/s^2

1. The capacitor charge Q is decreasing while the current I is positive is false

2. If the measured voltage in 2 is negative when the current I is positive, it is false.

3. When the measured VOLTAGE IN1 is positive, the capacitor charge Q is positive, which is True.

4. When the RELAY is thrown to the position N.O is False, the capacitor charge Q rapidly decays to zero.

5. This experiment's transient currents flow exponentially decrease to zero, which is false

A capacitor is a type of electric device that can charge and store electrical energy when a voltage is applied to its terminals.

Formulas link the applied voltage to the capacitor's charge Q and currents I.

The final formula shows that while the current is positive, the capacitor's voltage is positive (increasing) and the

Q=CV

I=dQ/dt=C(dQ/dt)

The charge is rising.

As a result, the question's assertion is false.

As the currect is flowing from VOLTAGE IN 2 to VOLTAGE IN 1 it will be positive.

As a result, the question's assertion is false.

The measured VOLTAGE IN1 is positive when the capacitor charge Q is positive.

As a result, the question's assertion is True.

The position of the relay is the N.O. position which stands for "normally opened", i.e. no current can flow through it.

As a result, the question's assertion is false.

The following formula provides the transient current flow in this experiment:
