Physics ! all multiple choice! 1.) does an object moving in uniform circular motion have constant centripetal acceleration? true or false 2.) how do the angular velocities of three knots on a rope compare as it is swung around in a circle? how about their speeds? a.) the angular velocity and linear velocities are the same b.) the linear velocities are the same, the angular velocity increases as you move toward the outside dot c.) the angular velocity is the same, the linear velocities are fastest in the center d.) the angular velocity is the same, the linear velocities are fastest on the outside e.) both the linear and angular velocities increase as you move out 3.) an object travels with a constant speed in a circular path. the net force on the object is a.) zero b.) toward the center c.) away from the center d.) tangent to the object's path

The electric field between square plates of a parallel-plate capacitor has magnitude e. the potential across the plates is maintained with constant voltage by a battery as they are pulled apart to twice their original separation, which is small compared to the dimensions of the plates. the magnitude of the electric field between the plates is now equal to a)e b)e/4 c)e/2 d)4e e)2e

An electron moves with a constant horizontal velocity of 3.0 × 106 m/s and no initial vertical velocity as it enters a deflector inside a tv tube. the electron strikes the screen after traveling 26 cm horizontally and 19 cm vertically upward with no horizontal acceleration. what is the constant vertical acceleration provided by the deflector? (the effects of gravity can be ignored.)
