The tallest volcano in the solar system is the 19 km tall martian volcano, olympus mons. an astronaut drops a ball off the rim of the crater and that the free fall acceleration of the ball remains constant throughout the ball’s 19 km fall at a value of 3.7 m/s 2 . (we assume that the crater is as deep as the volcano is tall, which is not usually the case in nature.) find the time for the ball to reach the crater floor. answer in units of s

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?
