Question

two balls at the same temperature collide , which is conserved
a) Temperature
b) velocity
c) momentum
d)) kinetic energy

Answer 1

answer : c

reason:

when two balls at the same temperature collide some fraction of their kinetic energy appear in other forms of energy like heat energy,sound energy.hemce neither temperature,not velocity or kinetic energy will remain conserved.the only quantity which will remain conserved is their momentum

hope it may help u

# be brainly

Answer 2

Ahoy!

_____________

When two balls collide at the same temperature then the momentum will be conserved only

Kinetic energy will not be conserved but there will be loss of heat so the temperature will also be inconserved . Velocity will also not be conserved hence there will be change in the momentum only .

P = mv

when a force does some work on the body the kinetic energy of the body increases by the same amount

conversely when an opposing force is applied on the body is kinetic energy decreases

The decrease in kinetic energy of the body is equal to the work done by the body against the retarding force .
