In Example 4.15 (p. 101), suppose a 52 cm diameter blade was attached to the motor shaft instead of the 76 cm diameter blade. If the fan blade experienced the same angular acceleration, what would happen to the magnitude of the tangential acceleration at the tip of the blade during the first few seconds

Although longitudinal waves can travel through all media types what is the disadvantage of this type of wave transmission? a) he efficiency of he wave transmission is greatly diminished as the media becomes less dense b) the oscillation of one set of particles has a huge impact on neighboring particles c) particles become too close together as they bump into each other making it more likely to hit other particles down the line
