An electron moving along the x axis has an initial speed of 1 × 106 m/s at the origin. its speed is reduced to 5 × 105 m/s at the point xp , 3 cm away from the origin. calculate the magnitude of the potential difference between this point and the origin. the mass of the electron is 9.109 × 10−31 kg and the elemental charge is 1.602 × 10−19 c. answer in units of v.

Explain earth's motion, using the terms "precession" and "rotation" in your answer.

In a game of pool, ball a is moving with a velocity v0 of magnitude v0 = 15 ft/s when it strikes balls b and c, which are at rest and aligned as shown. knowing that after the collision the three balls move in the directions indicated and assuming frictionless surfaces and perfectly elastic impact (that is, conservation of energy), determine the magnitudes of the velocities va, vb, and vc.

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?
