4. What is the frequency of an electromagnetic wave if it has a wavelength of 1.0 km?

Answers

The radio wave's wavelength is 1.0 m. A waveform signal that is carried in space or down a wire has a wavelength, which is the separation between two identical places (adjacent crests) in the consecutive cycles.

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

f = 3 x 108/1

f = 3 x 108 Hz is used,

Radio waves therefore have a frequency of 3 x 108 Hz.

The correct statement is "a nucleus whose mass is equal to the sum of the masses of its individual particles." The correct option is C.

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.

If you cool down a container of gas, there will be _______ collisions with the side of the container, resulting in ______ pressure.

Answers

A container of gas might lose pressure by cooling down because there are fewer collisions with the container's side.

What transpires when a container of gas is cooled?

When the gas in the supplied sealed jar is chilled, the molecules travel more slowly. This occurs because when the temperature drops, gaseous particles get closer to one another (on cooling). Upon cooling, there are also fewer accidents.

How does a gas's compression affect the frequency of collisions inside a container?

The container's capacity has shrunk, which reduces the distance the gas molecules must travel before colliding. As a result, there will be more collisions per second, increasing the pressure.

Interstitial lung disease is low lung compliance as a result, last of electrical lung tissue destruction.

Interstitial lung disorders brought on by breathing in particles like silicon and asbestos (asbestosis) can cause low lung compliance (silicosis).

Lungs and the pleural cavity have the capacity to expand and contract in response to variations in pressure. Lung compliance, which is a key determinant of lung health and function, is defined as the volume change per unit of pressure change across the lung. Lung compliance varies between inhalation and expiration because measurements of lung volumes vary between the two at the same pressure. Depending on whether only volume and pressure are measured (static) or whether their variations over time are also recorded, lung compliance can be classified as either static or dynamic.

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

Answers

Answer:

t = 0.97 s

Explanation:

Given that,

height, h = 4.7 m

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]

[tex]t = \sqrt{0.9592}[/tex]

t = 0.98 secs

Hence, the time it would take the object is 0.98 secs

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]

Rolling motion of any object occurs when the object starts sliding in a different methods from the other objects such as when the objects starts to roll from the ramp or any other sloppy surface and it rolls down due to the gravitational force and with many other forces such as the rolling tangential force. many forces are acting on the object at the same moment and we are just seeing the gravitational force which is playing a major portion. Hence by this information we can consider that the ball accelerates at a constant rate as it moves down the slope because of the constant gravitational force acting on it in a major portion and the rolling tangential force on the object is acting in the smaller form.

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.

Answers

Taking into account the definition of density, the density of a sample if its mass is 44.2 g and its volume is 22.1cm³ is 2 g/cm³.

Definition of density

Density is the ratio of mass to volume of a substance. In other words, density is a quantity that allows us to measure the amount of mass in a certain volume of a substance.

The expression for the calculation of density is:

density= mass÷ volume

This means that density (ρ) is equal to mass (m) divided by volume (v) and it is possible to deduce that density is inversely proportional to volume: the smaller the volume occupied by a certain mass, the greater the density.

Density is one of the physical properties of matter that can be observed in its different states: solid, liquid, and gas.

Density of the sample

In this case, you know that:

Mass= 44.2 gVolume= 22.1 cm³

Replacing in the definition of density:

density= 44.2 g÷ 22.1 cm³

Solving:

density= 2 g/cm³

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.

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.
