The uniform magnetic field at the pole face of a varies according to b.50 tcos (377. adt) where time tis in seconds. calculate the amplitude of the induced electric field at a radialdistance of 3.0 cm from the center

Work = force × a. work b. energy c. distance d. momentum

The charge on a charged sphere is: a)concentrated at its centerb)distributed uniformly throughout its volumec)clustered on its centerd)distributed uniformly over its surface

If a rock is thrown upward on the planet mars with a velocity of 12 m/s, its height (in meters) after t seconds is given by h = 12t − 1.86t2. (a) find the velocity of the rock after two seconds. m/s (b) find the velocity of the rock when t = a. 12−3.72a m/s (c) when will the rock hit the surface? (round your answer to one decimal place.) t = s (d) with what velocity will the rock hit the surface? m/s
