An object travels in a circular path of radius r at a constant speed v. What happens to the object's acceleration if the radius of the circle is
doubled and the speed stays unchanged? *
A) it doubles B)it quadrupled C)it is cut in 1/2 D)it is cut to 1/4 E)stays unchanged

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.)

Ne way in which elements differ from each other is the structure of the electron cloud in each element's atoms. in an electron cloud, an electron that is farther away from the nucleus has
