Two current‑carrying wires are perpendicular to each other. One wire lies horizontally with the current directed toward the east. The other wire is vertical with the current directed upward. Assume that the crossing point is the midpoint of each wire. What is the direction of the net magnetic force on the horizontal wire due to the vertical wire?

Which pair of quantities includes one quantity that increases as the other decreases during simple harmonic motion?

Astone is dropped from the upper observation deck of a tower, 250 m above the ground. (assume g = 9.8 m/s2.) (a) find the distance (in meters) of the stone above ground level at time t. h(t) = (b) how long does it take the stone to reach the ground? (round your answer to two decimal places.) s (c) with what velocity does it strike the ground? (round your answer to one decimal place.) m/s (d) if the stone is thrown downward with a speed of 2 m/s, how long does it take to reach the ground? (round your answer to two decimal places.) s
