Answer:
A longitudinal wave is a wave in which particles of the medium move in a direction parallel to the direction that the wave moves.

Answer:
Assuming air resistance is negligible, all of the potential energy that the object has at the top of the ramp is converted into kinetic energy by the time it gets to the bottom of the ramp. This is because no matter what path the object takes to move the 5m vertically (ie. falling straight down v. sliding on the ramp), gravity does the same amount of work on it.
Thus, calculate the total amount of potential energy at the top of the ramp:
Ep=mgh
Ep=4(9.81)5
Ep=196.2 Joules
Because all of this potential energy is converted into kinetic energy in the object by the bottom of the ramp, the object hits the spring with 196.2J of energy.
By using the formula for elastic potential energy, you can calculate exactly how far the spring compresses.
196.2=(1/2)k(x^2)
392.4=(350)(x^2)
1.1211=x^2
sqrt(1.1211)=x
x=1.059m
As for the last part of the question, after the object compresses the spring fully and stops momentarily, the spring converts it's elastic potential energy back into kinetic energy in the object and pushes it away again.
Explanation:
nuclear energy
Explanation:
The sunlight that reaches earth is generated by a transformation of nuclear energy. Radiant energy is a from of energy that reaches the earth from nuclear reactions in the core of the sun.
- In this process, light nuclei combines to form larger ones through the process of nuclear fusion.
- This process does not conserve energy and mass is converted to energy.
- The nuclear reaction produces huge energy that goes into the solar system space and lights it up.
- Therefore, it is a transformation of nuclear energy into radiant energy.
- The radiant energy is made up of electromagnetic radiations.
