Answer: Solids
Explanation: Solids have very little movement and the particles have barely enough movement to vibrate. We can't see it but the particles are indeed vibrating. Solids have the least amount of kinetic energy which is moving energy.
Answer:
Temperature will be 305 K
Explanation:
We have given The asteroid has a surface area 
Power absorbed P = 3800 watt
Boltzmann constant 
According to Boltzmann rule power radiated is given by




So temperature will be 305 K
Answer:
Part a)

Part b)
Here final kinetic energy is more than the initial kinetic energy
This increase in kinetic energy is due to spring connected between them as the spring energy is converted into kinetic energy of two blocks
Explanation:
Part a)
As we know that there is no external force on the system of two gliders
So here we can use momentum conservation for two gliders
So we will have




Part b)
now we will have
initial kinetic energy of both gliders is given as


Final kinetic energy of two gliders


so here final kinetic energy is more than the initial kinetic energy
This increase in kinetic energy is due to spring connected between them as the spring energy is converted into kinetic energy of two blocks
