Two people carry a heavy electric motor by placing it on a light board 1.50 m long. One person lifts at one end with a force of 410 N, and the other lifts the opposite end with a force of 710 N.
a. What is the weight of the motor?
b. Where along with the board is its center of gravity located?
c. Suppose the board is not light but weighs 200, with its center of gravity at its center, and the two people each exert the same forces as before. What is the weight of the motor in this case?
d. Where is its center of gravity located?

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 !
