The option “The sum emitting light energy” does not describe the conversion of potential energy to kinetic energy.
Answer: Option A
<u>Explanation:
</u>
The potential energy, the object's energy at rest while the kinetic energy is the energy the object in motion. So among the options given, a rocket leaving the Earth's atmosphere consists of conversion of potential energy as the thrusting force to kinetic energy of the movement of the rocket to space.
Similarly the stretching of rubber band is a form of elastic potential energy and when it is released, the band will vibrate which will be the converted kinetic energy.
Also, the avalanche is the falling of ice berg which were once in rest, so the potential energy of the ice berg will get converted to kinetic energy during avalanche.
The option that is the sun emitting light does not convert potential to kinetic energy, instead it converts potential to light energy.
Answer:

Answer:
Place theory.
Explanation:
Place theory explains the different perception of sounds on the basis of the different sound waves. This theory helps to explain how the individual can differentiate different pitch sounds.
The different sound frequency causes vibration at the basilar membrane of the cochlea. The different areas of cochlear membrane gets activated by the different frequency of sound. These different vibration enable to distinguish between high pitch and low pitch sounds.
Thus, the answer is place theory.

Answer: 300 turns
Explanation: In order to explain this problem we have to consider the relationship between the voltage for the primiry and secondary and the turns for their coils.
This expression is consequence of the Faraday law because the magnetic flux is the same for both coils then the induced emf are the same for both circuits.
They are reñated as follow:
Vs=Vp*Ns/Np where Vs and Vp are the voltage for the secondary and primary coil, respectively.
Ns and Np are the turns for the secondary and primary coil, respectively.
Then we have:
Ns=Vs*Np/Vp= 16*2250/120=300
