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.

Ablock of mass m = 2.5 kg is attached to a spring with spring constant k = 740 n/m. it is initially at rest on an inclined plane that is at an angle of theta= 26 with respect to the horizontal, and the coefficient of kinetic friction between the block and the plane is uk = 0.17. in the initial position, where the spring is compressed by a distance of d = 0.16 m, the mass is at its lowest position and the spring is compressed the maximum amount. take the initial gravitational energy of the block as zero. the block's initial mechanical energy is 9.472 j.b. if the spring pushes the block up the incline, what distance l in meters will the block travel before coming to rest? the spring remains attached to both the block and the fixed wall throughout its motion.
