A85 g particle undergoes shm with an amplitude of 2.0 mm, a maximum acceleration of magnitude 8.1 x 103 m/s2, and an unknown phase constant φ. what are (a) the period of the motion, (b) the maximum speed of the particle, and (c) the total mechanical energy of the oscillator? what is the magnitude of the force on the particle when the particle is at (d) its maximum displacement and (e) half its maximum displacement? a 65 kg solid sphere with a 14 cm radius is suspended by a vertical wire. a torque of 0.50 n·m is required to rotate the sphere through an angle of 0.95 rad and then maintain that orientation. what is the period of the oscillations that result when the sphere is then released?

Imagine an isolated positive point charge q (many times larger than the charge on a single proton). there is a charged particle a (whose charge is much smaller than charge q) at a distance from the point charge q. on which of the following quantities does the magnitude of the electric field created by charge q at particle a's position depend? check all that apply.the type of the charge on the charged particle athe relative orientation between q and a (while the distance between q and a is fixed)the specific location of the charged particle a (while the distance between q and a is fixed)the amount of the charge on the point charge qthe specific location of the point charge q (while the distance between q and a is fixed)the distance between the point charge q and the charged particle athe amount of the charge on the charged particle a
