Consider a long, uniformly charged, cylindrical insulator of Radius R with charge density 1.0uC/m^3. What is the magnitude of the electric field inside the insulator at a distance 1cm form the axis

Acup of coffee sits on the dashboard of an automobile. the car goes around a sharp curve. even though you hold the cup still, coffee still splashes out. this can best be explained due to a) density. b) friction. c) gravity. d) inertia.

Match each scenario to the form of energy it represents

Apotter's wheel moves uniformly from rest to an angular speed of 0.20 rev/s in 32.0 s. (a) find its angular acceleration in radians per second per second. rad/s2 (b) would doubling the angular acceleration during the given period have doubled final angular speed?
