Atruck driving along a highway road has a large quantity of momentum. if it moves at the same speed but has twice as much mass, what will happen to its momentum? a. zero. b. quadrupled. c. doubled. d. unchanged.

C

Explanation:

Given

Truck is moving with a large momentum let say P

P is the product of mass and velocity such that if m is the mass and v is the velocity then P is given by

if mass is doubled while v remain same, New momentum is given by

Momentum gets doubled  

the answer is false. this is because for ice to melt, it requires latent heat of melting. latent heat means heat energy required to change phase without any increase in temperatures. therefore, the ice will take energy from the environment to melt hence atmospheric temperatures will reduce.
