Describe how charged particles move in uniform magnetic fields. Consider cases where the velocity is perpendicular to the field and when it is not perpendicular to the field. Explain how this principle is used in a mass spectrometer to identify molecules present in an unknown substance.

The electrical breakdown of an insulator occurs when an electric
field becomes large enough to ionize the insulator, allowing
electrical current to flow; lightning is an example of the
electrical breakdown of air. The electrical breakdown of air occurs
when the electric field reaches about 3×106 N/C . Estimate the
magnitude of the total static charge on your body ?body...

a) The rotor of a helicopter is gaining angular speed with constant angular acceleration. At t = 0 it is rotating at 1.25 rad/s. From t = 0 to t = 2.00 s, the rotor rotates through 8.00 rad. What is the angular acceleration of the rotor? b) Through what angle (in radians) does the rotor rotate from t =...
