Explanation:

Answer:

a) Eg = 3,060.72 j

b) Ek = 2,080 j

c) Etotal = 5,140.72 j

Explanation:

The given parameters are;

The mass of the person, m = 65 kg

The height of the person, h = 4.8 m

The speed of the person, v = 8.0 m/s

a) The gravitational potential energy, [tex]E_g[/tex] = m·g·h

Where;

g = The acceleration due to gravity ≈ 9.81 m/s²

∴ Eg = 65 kg × 9.81 m/s² × 4.8 m = 3,060.72 j

Eg = 3,060.72 j

b) The kinetic energy, Ek = 1/2·m·v²

∴ Ek = 1/2 × 65 kg × (8.0 m/s)² = 2,080 j

Ek = 2,080 j

c) The constant total Mechanical Energy, Etotal = Eg + Ek

∴ Etotal = 3,060.72 j + 2,080 j = 5,140.72 j

Etotal = 5,140.72 j.

Answer:

Vibration means quickly moving back and forth (or up and down) about a point of equilibrium. ... Something that is vibrating may shake at the same time. If it vibrates in a regular way, it may produce a musical note because it can make the air vibrate. This vibration will send sound waves to the ear and to the brain.

Explanation:

Vibration, periodic back-and-forth motion of the particles of an elastic body or medium, commonly resulting when almost any physical system is displaced from its equilibrium condition and allowed to respond to the forces that tend to restore equilibrium.

Answer:

The magnitude of the force required to move the electron through the given field is 2.203 N

Explanation:

Given;

The field strength of the electron, E = 1.375  x 10¹⁹ N/C

charge of electron, q = 1.602 x 10⁻¹⁹ C

The magnitude of the force required to move the electron through the given field is calculated as follows;

F = Eq

F = (1.375  x 10¹⁹ N/C) (1.602 x 10⁻¹⁹ C)

F = 2.203 N

Therefore, the magnitude of the force required to move the electron through the given field is 2.203 N

Answer:

A.

Explanation:

Speed and velocity both require more than one component to be solved but acceleration is independant.

Answer:

The correct option is (a).

Explanation:

Given that,

Current flowing through the resistor, R = 0.054 A

Resistance of the resistor, R = 15 ohms

We need to find the voltage. We know that, Ohm's law gives the relation between voltage, current and resistance i.e.

V = IR

Put all the values,

[tex]V=0.054 \times 15\\\\V=0.81\ V[/tex]

So, the required voltage is equal to 0.81 volts.

Question:

A roller-coaster vehicle has a mass of 500 kg when fully loaded with passengers.  If the vehicle has a speed of 20.0 m/s at point A, what is the force exerted by the track on the vehicle at this point?

See attachment

Answer:

33700 Newton

Explanation:

Given

[tex]m = 500kg\\v = 24.0m/s\\r=10m[/tex]

First, we determine the forces acting on mass m.

They are: the force exerted by the track (Fn) and the weight of the vehicle (W)

So, the net force is:

[tex]F_{net} = F_n - W[/tex]

[tex]W=mg[/tex]

So:

[tex]F_{net} = F_n - mg[/tex]

Make Fn the subject

[tex]F_n = F_{net} + mg[/tex]

Fnet is calculated as:

[tex]F_{net} = F_c = \frac{mv^2}{r}[/tex] --- i.e. the centripetal force

So:

[tex]F_n = F_{net} + mg[/tex]

[tex]F_n = \frac{mv^2}{r} + mg[/tex]

[tex]F_n = \frac{500 * 24^2}{10} + 500 * 9.8[/tex]

[tex]F_n = 28800 + 4900[/tex]

[tex]F_n = 33700N[/tex]

Answer:

E = 10078.32 J

Explanation:

Given that,

The weight of a window cleaner, F = 839.86 N

The window cleaner is cleaning windows on the 4th floor of a building at a height of 12 m.

We need to find the potential energy of the window cleaner. We know that the potential energy of an object is given by :

E = mgh

Put values,

E = 839.86 × 12

E = 10078.32  J

So, the window cleaner will have 10078.32  J of potential energy.

Answer: 5V

Explanation: because 2 goes into 10, five times. Also I know it’s correct cuz I got it right in my quiz

The difference in potential between these two points is 5 V.

The electric potential between two points is the work done in taking a unit postive charge from one point to another.

The difference in potential between these two points is calculated as follows;

W = qV

V = W/q

V = 10/2

V = 5 V

Thus, the difference in potential between these two points is 5 V.

Explanation:

Swampy areas are a transition area formed where water and dry lands tend to meet. Swampy areas are actually forested areas with contains moist and humid weather conditions which has necessitated the wet soil around such an environment.

Florida is a very typical example of a weather that supports the creation of swampy areas due to its humid, heavy rains, water spouts,turnadoes etc and other extreme weather conditions.

Answer:

v = 6.72 m/s

Explanation:

Given that,

Vertical height, h = 2.31 m

We need to find the speed at the bottom of the slide. Let the speed be v. We can find it using the conservation of energy such that,

[tex]\dfrac{1}{2}mv^2=mgh\\\\v=\sqrt{2gh}[/tex]

Put all the values,

[tex]v=\sqrt{2\times 9.8\times 2.31} \\\\v=6.72\ m/s[/tex]

So, her speed at the bottom of the slide is equal to 6.72 m/s.

Answer:

The wavelength is 1.7cm

Explanation:

Given

See attachment for wave pattern

Required

What is the wavelength

To do this, we simply calculate the distance between successive waves (see attachment 2 for point A and B)

Using the ruler, points A and B are at:

[tex]A = 0.6cm[/tex]

[tex]B = 2.3cm[/tex]

So, the wavelength is:

[tex]\lambda = B - A[/tex]

[tex]\lambda = 2.3cm - 0.6cm[/tex]

[tex]\lambda = 1.7cm[/tex]

If approximated, the wavelength is:

[tex]\lambda \approx 2cm[/tex]

A 1,100 kg car is going at 22 m/s. Force is needed to stop it in 20

seconds is 1210 N.

A force is an effect that can alter an object's motion according to physics. An object with mass can change its velocity, or accelerate, as a result of a force. An obvious way to describe force is as a push or a pull. A force is a vector quantity since it has both magnitude and direction.

Using equation of motion,

v = u +  at

0 = 22 + a.20

a = 1.1 m/sec²

force = mass.acceleration

force = 1100.(1.1)

force = 1210 N.

Your welcome

The Sun creates energy through a series of steps known as nuclear fusion.

Nuclear fusion is the process by which atomic nuclei combine to form heavier nuclei, releasing a tremendous amount of energy in the process. In the Sun, this process occurs in the core, where the temperature and pressure are high enough to overcome the electrostatic repulsion between positively charged atomic nuclei. Hydrogen atoms are fused together to form helium atoms, releasing energy in the form of light and heat.

The process of nuclear fusion in the Sun can be broken down into several steps.

The first step involves the collision of two hydrogen atoms to form a deuterium atom, releasing a positron and a neutrino in the process. The deuterium atom can then combine with another hydrogen atom to form helium-3, releasing a gamma ray. Finally, two helium-3 atoms can combine to form helium-4, releasing two protons and releasing even more energy in the process.

Therefore, the process of nuclear fusion in the Sun is a complex series of steps that releases a tremendous amount of energy and is responsible for the light and heat that we receive on Earth.
