Apiece of driftwood moves up and down as water waves pass beneath it. however, it does not move toward the shore with the waves. what does this demonstrate about the propagation of waves through a medium?
a) waves transmit energy but not matter as they progress through a medium.
b) waves transmit matter but not energy as they progress through a medium.
c) waves do not transmit matter or energy as they progress through a medium.
d) waves transmit energy as well as matter as they progress through a medium.

The experiment done in lab is repeated, using a ball that has unknown mass m. you plot your data in the form of f 2 versus m/l, with f in rev/s, m in kg, and l in m. your data falls close to a straight line that has slope 3.19 m/(kg · s2). use g = 9.80 m/s2 and calculate the mass m of the ball.

It may seem strange that the selected velocity does not depend on either the mass or the charge of the particle. (for example, would the velocity of a neutral particle be selected by passage through this device? ) the explanation of this is that the mass and the charge control the resolution of the device--particles with the wrong velocity will be accelerated away from the straight line and will not pass through the exit slit. if the acceleration depends strongly on the velocity, then particles with just slightly wrong velocities will feel a substantial transverse acceleration and will not exit the selector. because the acc
