A300 g block connected to a light spring with a force constant of k = 3 n/m is free to oscillate on a horizontal, frictionless surface. the block is displaced 3 cm from equilibrium and released from rest. find the period of its motion. (recall that the period, t, and frequency, f, are inverses of each other.)

When a light bulb shines, it gives off light energy and energy. a. heat b. potential c. chemical d. electrical

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 !
