Newton's second law states that the force produced by a moving object depends on its mass and acceleration. which is an example of this? a. two boulders move at the same rate of acceleration; the boulder with the smaller mass produces a greater force.
b. two boulders move at the same rate of acceleration; the boulder with the greater mass produces a greater force.
c. a runner accelerates at a rate of 1 meter per second per second during a race.

Given the position vector of the particle r(t)=(t+1)i+(t^2−1)j+2t k, find the particle's velocity and acceleration vectors at t=1

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 !

Match each scenario to the form of energy it represents
