Answer:
Time period between the successive beats will be 0.1703 sec
Explanation:
We have given speed of the sound v = 349 m/sec
Wavelength of piano
Wavelength of piano
So frequency of piano A
Frequency of piano B
So beat frequency f = 455.61 - 449.74 = 5.87 Hz
So time period
So time period between the successive beats will be 0.1703 sec

Explanation:
1 full revolution is let \theta be the angle of Ron's position.
At t = 0.
one full revolution occurs in 12 sec, so his angle at t time is
r is radius of circle and it is given as
for r = 30 sec
however, that is centered at (0,0) and the positioned at time t = 0 is (30,0). it is need to shift so that the start position is (30,45). it can be done by adding to y
