A circular beam of charge of radius a consists of electrons moving with a constant speed u along the +z direction. The bean's axis is coincident with the z axis and the electron charge density is given by rhov = -cr^2, where c is a constant and r is the radial distance from the axis of the beam. a) Determine the charge density per unit length. b) Determine the current crossing the z-plane.

the equation above shows how temperature f, measured in degrees fahrenheit, relates to a temperature c, measured in degrees celsius. based on the equation, which of the following must be true?

Power braking's benefits

Among the big advantages of a power braking system are it's: Regarded as safer. The heat caused by the friction of drum brakes causes them to wear down. Because disc brake systems have better heat distribution, they're more efficient
