Humpty Dumpty (12 kg) sat on a wall (2 m high). What was his potential energy, before his great fall? A. 235.2 J B. 235.2 N C. 24 J D. 246.1 W

Answers

Answer 1

Answer: I think it would be B. P.E.=mgh, the mass is 12g, gravitational force is 9.8, and the wall is 2 meters high, so multiply it all and get 235.2.

Answer 2

Answer: It would be 24J because there's no energy.

Explain Newton's third law in your own words.

Answers

Newton's third law states "for every action, there is an equal and opposite reaction."

What this is pretty much saying is that for every action, there is a consequence. One force connects and triggers another.

Newton's third law says, " For every action, there is an equal and opposite reaction."

The magnitude of action and reaction are equal but the direction is opposite.

Rarefaction occurs only in a longitudinal wave.

What is refraction?

A light beam refracts whenever it reaches an angled material with a different refractive index. A change in direction results from this acceleration. As an example, consider air entering the water. The speed of the light decreases as it continues to travel at a changingangle.

Transverse waves do not experience rarefaction, which is a phenomenon that only happens in longitudinal waves.

This is due to the fact that longitudinal waves cause the medium through which they travel to be compressed and rarefied.

Transversewaves, however, feature oscillations that are parallel to the direction of the wave.

With a longitudinal wave, the medium's particles are moved along with the wave in the same direction.

Both zones of compression and rarefaction result from this, with the former having the particles closer together than they would be in their equilibrium state.

The wave is produced by the pattern of compression and rarefaction.

Due to the displacement of the medium's particles in the same direction as the wave's propagation, rarefaction only happens in longitudinal waves, where it results in places where the particle spacing is greater than it would be in the equilibrium state.

The correct answer to the question is : B) Longitudinal wave.

EXPLANATION:

Before coming into any conclusion, first we have to understand the nature of sound wave.

The sound wave is a longitudinal wave in which the direction of vibration of particles are parallel to the direction of wave propagation.

In this type of wave, one will find compression and rarefaction. Compression is the high pressure region in which the particles are closely aggregated to each other.

Rarefaction is the low pressure region in which the particles are far away from each other. There is large separation between particles as compared to compression.

Hence, the correct answer is sound wave.

What do we call the minimum energy that is required by an electron to leave the metal target in the photoelectric effect?Select one of the options below as your answer: A. energy function B. minimum function C. work function D. quanta E. electrical energy

Answers

Answer:

C. work function

Explanation:

In the photoelectric effect, the energy of the incident photon is used in part to extract the electron from the metal (and this energy is called work function) and the rest is converted into kinetic energy of the electron. In formula:

$hf = \phi +K$

where

hf is the energy of the incident photon, which is the product between h (the Planck constant) and f (the photon's frequency)

$\phi$ is the work function

K is the kinetic energy of the photoelectron as it leaves the material

The work function is what we call the minimum energy that is required by an electron to leave the metal target in the photoelectric effect.
