If 2 objects have the same momentum which statement is true a. mass and velocity are the same for both b. they both have the same mass c. the product of mass x velocity is the same for both d. they both have the same velocity

C is the correct option

As momentum = (mass) (velocity)

P=mv

So the object having greater mass has less velocity and the object having smaller mass will move faster. But product of mass and velocity is same to each other.

their crystal patterns have been disrupted by stress

what is the actual question though?
