How many legs does an arachnid have?

1pt A ball with mass (m) is dropped from a certain height. Which equality could be rearranged to find the velocity of the ball after it has fallen through a certain distance? A. (1/2) mv2 = mgah B. (1/2) mv2 = (1/2) kx2 c. 1/2mv2 = kq1q2/r D.

A projectile travels above level ground. The initial vertical component of its velocity is 0.90 m/s and the initial horizontal component of its velocity is 0.60 m/s.

Magnetic fields are produced by: atoms currents voltages charges

According to kepler's second law, jupiter will be traveling most slowly around the sun when at

Two balls of equal mass are thrown horizontally with the same initial velocity. They hit identical stationary boxes resting on a frictionless horizontal surface. The ball hitting box 1 bounces back, while the ball hitting box 2 gets stuck.

Electricity problem (coulomb's law)

An observer (O) spots a plane (P) taking off from a local airport and flying at a 29° angle horizontal to her line of sight and located directly above a tower (T). The observer also notices a bird (B) circling directly above her.
