Acircuit consists of a conducting movable bar and a lightbulb connected to two conducting rails as shown in the figure below. an external magnetic field is directed perpendicular to the plane of the circuit. which of the following actions will make the bulb light up? (select all that apply.)

the bar is moved to the left.
the bar is moved to the right.
the magnitude of the magnetic field is increased.
the magnitude of the magnetic field is decreased.
the bar is lifted off the rails.

Aplane travels 1000 miles in 5 hours .what is the planes average speed?

Asilver dollar is dropped from the top of a building that is 1324 feet tall. use the position function below for free-falling objects. s(t) = −16t2 + v0t + s0 (a) determine the position and velocity functions for the coin. s(t) = v(t) = (b) determine the average velocity on the interval [1, 2]. ft/s (c) find the instantaneous velocities when t = 1 second and t = 2 seconds. v(1) = ft/s v(2) = ft/s (d) find the time required for the coin to reach the ground level. (round your answer to three decimal places.) t = s (e) find the velocity of the coin at impact. (round your answer to three decimal places.) ft/s
