Name the forces acting on a plastic bucket containing* water held above ground level in your hand, Discuss why the forces acting on the bucket do not bring a change in its state of motion.

The experiment was repeated many years later but the gases were mixed in a different type of container. a white solid was obtained which was xenon fluoride. predict whether you think 1) krypton and 2) radon will react with fluorine. explain reasons for your predictions

Suppose that a mass of 2 kg is attached a spring whose spring constant is 50. the system is damped such that b = 12 . the mass is set in motion with an initial velocity of -8 m/s at a position 0 meters from equilibrium. set up and solve a differential equation that models this motion. write your solution in the form a cos ( ω t − α ) where α is a positive number. use your solution to fill in the information below: what is the amplitude of the motion? what is the value of ω ? what is the phase shift?

Aproper cool-down routine does which of the following? a). motivates you for your next workout b). the body adjust back to a resting state c). leaves you feeling worn-out d). strengthens muscles
