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

the answer is 1 i believe

i just calculated it all out, and not including weekends, and all the different days off. as of this school year (2018-2019) students are spending 2198 hours in school this year
