How can a wave carry information? A. The transmitter changes the form of the wave. The receiver then decodes the changes that have been made to the wave.

B. The transmitter changes the angle in which the wave is sent. The receiver detects the changes in the angle and decodes them.

C. The transmitter changes the wave type between mechanical and electromagnetic. The receiver detects and decodes these switches.

D. The transmitter sends a wave. The receiver reflects this wave. The transmitter then decodes the changes made to the wave.

This problem has been solved! see the answera non-uniform fire escape ladder is 6.0m long whenextended to the icy alley below. it is held at the top by africtionless pivot, and there is neglibible frictional force fromthe icy surface at the bottom. the ladder weighs 250n, and it'scenter of gravity is 2.0m along the ladder from the bottom. amother and child of total weight 750n are on the ladder 1.5m fromthe pivot. the ladder makes an angle θ with the horizontal. find the magnitude and direction ofa) the force exerted by the icy alley on the ladderb) the force exerted by the ladder on the pivotc) do your answers in part a and b depend on the angle?

Use the right-hand rule for magnetic force to determine the charge on the moving particle. this is a charge.
