What happens to the momentum of two cars when they collide? The total momentum after the collision is equal to the total momentum before the collision.

The total momentum after the collision decreases.

The total momentum after the collision increases.

The total momentum before and after the collision is not conserved.

What type of light does this light bulb produce most (i.e. at what wavelength does the spectrum have maximum intensity)?

This is important 1. what happens to the speed of molecules in water vapor when it condenses to form a liquid? (2 points) the molecules slow down. the molecules speed up. the molecules slow down and then speed up. the molecules speed up and then slow down. 2. how might human activities change to compensate for a decrease in water supplies? (2 points) humans might build a factory. humans might build drainage systems. humans might extract more water from the ground. human behavior does not change because of the water cycle. i'll be grateful if anyone can answer these 2 questions !

More solar radiation is absorbed by earth’s surface than by
