A pollen grain has a maximum electric charge it can carry before the electric field it generates exceeds the dielectric limit for air of 3 × 10 6 N / C . 3×106 N/C. Estimate the magnitude of the maximum voltage V max Vmax at the surface of a pollen grain that is carrying its maximum electric charge, assuming V = 0 V=0 at infinity.

Samir watches a 100-minute movie on his spaceship. maria's spaceshipe flies in the same direction as samir's spaceship but she observes his move to last 125 minutes and his spaceship to be 40 m long. how long does samir observe his own spaceship to be? according to an observer on earth, planet x is stationary. maria and samir depart earth on their spaceships at the same time, each flying at 0.5c. maria flies toward planet x and samir flies in the opposite direction. according to maria, her voyage to planet x takes 9 years. how many years does marias voyage take according to samir?
