Explanation:
Answer:
Thermal energy
Explanation:
The thermal energy associated with the random motions of the atoms or molecules.
When the temperature of the substances rise then their molecule starts to vibrate within the system and the energy associated with the vibration of the molecule is known as thermal energy.The responsible factor for the rise in temperature is thermal energy.
Therefore answer is --
Thermal energy
The answer is D. 2:1 since the input force is half the output force that corresponds to a 2:1 ratio of input to output.
The beginning development of a
star is marked by a supernova explosion, with the gases present in the nebula
being forced to scatter. As the star shrinks, radiation of the surface increases
and create pressure on the outside shell to push it away and forming a
planetary nebula or white dwarf.
