A long, cylindrical solenoid with 100 turns per centimeter has a radius of 14.7 cm. If the current through the solenoid changes at the rate 6.21 A/s, what is the emf induced per unit length along the axis of the solenoid?

Picture a all traveling at a constant speed around the inside of a circular structure. is the ball accelerating? explain your answer

Orque can be calculated by multiplying the force (n) applied at 90? to the lever arm at a distance (m) from the pivot point (point of rotation), the compound si unit for the torque is n? m. if the force (at 90? to the lever arm) applied is 15 n and it is applied at 2.0 m from the pivot point (point of rotation), what is the torque on the lever?
