I’m not sure what variables you are given, but since work = force x distance, and force = mass x acceleration, you could use work = mass x acceleration x distance
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.
The equator would be warmer than the poles. :)

Explanation:
Physical Property: A property of matter that can be seen, felt, tasted, smelled, or heard.
Physical Change: The change of an object of matter's physical property/properties.
Chemical Property: An element/object of matter's internal property/properties
Chemical Change: An element/object of matter's internal property/properties being altered or changed
Answer:
Look at work
Explanation:
Θ= 4t^3+10t-40
a) In order to find ω, we need to find displacement so plug in t=2 to find Θ.
Θ= 4*8+20-40=12
use ω=Θ/t
Plug in values
ω=6 rad/s
b) In order to find α we use ω/t.
Plug in values
α=6/2= 3 rad/s^2
