The current flowing in a solenoid that is 20.3 cm long and has a radius of 2.40 cm and 526 turns decreases from 3.39 A to 1.03 A in 0.270 s. Determine the magnitude of the induced electric field inside the solenoid 1.20 cm from its center.

The difference between a red shift and a blue shift has to do with wavelength frequency. t or f

Properties seen when one one substance changes to another are known as properties

An athlete swings a ball, connected to the end of a chain, in a horizontal circle. the athlete is able to rotate the ball at the rate of 8.13 rev/s when the length of the chain is 0.600 m. when he increases the length to 0.900 m, he is able to rotate the ball only 6.04 rev/s. (a) which rate of rotation gives the greater speed for the ball? 6.04 rev/s 8.13 rev/s (b) what is the centripetal acceleration of the ball at 8.13 rev/s? m/s2 (c) what is the centripetal acceleration at 6.04 rev/s? m/s2
