Question 1

For the wave described by y = 0.02 sin (kx) at t = 0 s, the first maximum at a positive x coordinate occurs where x = 4 m. Where on the positive x axis does the second maximum occur?

20 m

18 m

24 m

28 m

16 m


Question 2

If y = 0.02 sin (30x 400t) (SI units) and if the mass density of the string on which the wave propagates is 0.005 kg/m, then the transmitted power is

1.03 W

2.13 W

4.84 W

5.54 W

106 W
