Which process could cause ice to form a thin layer over a lake? freezing sublimation evaporating condensation

A : Freezing

Explanation:

Come on, it's common sense that the the reason for the answer is freezing.

The lake is not condensing because it is already condensed into the water in the lake...

The lake is not sublimating because it is not releasing gases from a solid...

As well as the lake is not evaporating if it says that it forms a layer of ice.

(newtons first law)

conservation of momentum law states :

momentum before collision = momentum after collision

momentum p (kg-m/s)= mass * velocity

say moving car=1 000 kg, velocity = 10 m/s then p = 1 000*10= 10 000 kg-m/s

say still car = 2 000 kg, velocity = 0 m/s then p = 2 000* 0 = 0 kg-m/s

total momentum prior to collision = 10 000 + 0 = 10 000 kg-m/s

momentum after collision = 10 000 kg-m/s

mass now = 1 000 kg+2 000 kg = 3 000 kg

10 000 = 3 000 kg* velocity m/s

10 000/3 000 = velocity

3.33 m/s = velocity after collision

an impulse is a force applied over time , momentum is exclusive of external forces and a perfect collision is implied
