Anew process converts potential energy of an object to kinetic energy. neither work nor eat is added to the system. no reaction takes place. what determines the velocity of the anew bject? not sure all of the above elevation of the process change in height of the object mass of the object

Change in height of the object

Explanation:

Change in height of the object

Since ,

We know potential energy can be written as mgh where

P.E. = mgh

M = mass ,

g = gravity constant

h = height

Kinetic energy can be written as 0.5 mv²

So , the Potential energy = kinetic energy

Then ,

velocity of object = √2 gh

Since g is a constant ,

Hence ,

Height of object will determine the velocity.

answer

fusion: the energy source of stars. the energy released from the collapse of the gas into a protostar causes the center of the protostar to become extremely hot. when the core is hot enough, nuclear fusion commences. fusion is the process where two hydrogen atoms combine to form a helium atom, releasing energy.
