Any body moving with simple harmonic motion is being acted on by a force that is:. a) proportional to a sine or cosine function of the displacement
b) directly proportional to the displacement
c) proportional to the inverse square of the displacement
d) constant

Aspring with a mass of 2 kg has a damping constant 14 kg/s. a force of 3.6 n is required to keep the spring stretched 0.3 m beyond its natural length. the spring is stretched 0.6 m beyond its natural length and then released. find the position of the mass at any time t. (assume that movement to the right is the positive x-direction and the spring is attached to a wall at the left end.)

Describe different biomes. what are some adaptations that organisms (plants or animals) must have to live in each biome?

In a system, when potential energy decreases, then entropy also decreases. true false
