Acharged capacitor with c = 780 μf is connected in parallel to an inductor that has l = 0.290 h and negligible resistance. at an instant when the current in the inductor is i = 2.40 a , the current is increasing at a rate of di/dt=89.0a/s. what is the maximum voltage across the capacitor?

Athin plate moves between two parallel, horizontal, stationary flat surfaces at a constant velocity of v = 7.5 m/s. the two stationary surfaces are spaced 4 cm apart, and the medium between them is filled with oil whose viscosity is 0.9 n·s/m2. the part of the plate immersed in oil at any given time is 2 m long and 0.5 m wide. if the plate moves through the mid-plane between the surfaces, determine the force required to maintain this motion. what would your response be if the plate was 1 cm from the bottom surface (h2) and 3 cm from the top surface (h1)? if the plate moves through the mid-plane between the surfaces, the force required to maintain the motion will be n. if the plate was 1 cm from the bottom surface (h2) and 3 cm from the top (h1) surface, the force required to maintain the motion would be n.

Could someone . i have tried to solve myself but my calculation is off
