Atransverse harmonic wave travels on a rope according to the following expression: y(x, t) = 0.12sin(2.2x + 17.6t)

the mass density of the rope is ? = 0.116 kg/m. x and y are measured in meters and t in seconds.

1) what is the amplitude of the wave?

2) what is the frequency of oscillation of the wave?

3) what is the wavelength of the wave?

4) what is the speed of the wave?

5) what is the tension in the rope?

6) at x = 3.9 m and t = 0.45 s, what is the velocity of the rope? (watch your sign)

7) at x = 3.9 m and t = 0.45 s, what is the acceleration of the rope? (watch your sign)

8) what is the average speed of the rope during one complete oscillation of the rope?

9) in what direction is the wave traveling?

+x direction

-x direction

+y direction

-y direction

+z direction

-z direction

10) on the same rope, how would increasing the wavelength of the wave change the period of oscillation?

the period would increase

the period would decrease

the period would not change

Ahair dryer is basically a duct in which a few layers of electric resistors are placed. a small fan pulls the air in and forces it through the resistors where it is heated. air enters a 1200 w hair dryer at 100 kpa and 22Ā°c and leaves at 47Ā°c. the cross-sectional area of the hair dryer at the exit is 60 cm2. neglecting the power consumed by the fan and the heat losses through the walls of the hair dryer, determine (a) the volume flow rate of air at the inlet and (b) the velocity of the air at the exit.
