At the top of a 9m tall hill, a car has a velocity of 4 m/s, a mass of 1200 kg. Complete the TE chart below if the car rolls to the bottom of the hill. Find the velocity of the car at the bottom of the hill. i really need it ​

Aspecified volume of space contains an electric field for which the magnitude is given by e=e0cos(ωt). suppose that e0 = 20 v/m and ω = 1.0 × 107 s−1. part a what is the maximum displacement current through a 0.80 m2 cross-sectional area of this volume? express your answer with the appropriate units. idisp,max i d i s p , m a x = nothing nothing request answer part b how would this area have to be oriented relative to the electric field to get this maximum displacement current?
