A500 hz whistle is moved toward a listener at a speed of 10 m/s. at the same time, the listener moves at a speed of 20 m/s in a direction away fromm the whistle. what is the apparent frequency heard by the listener? (the speed of sound is 340 m/s)
a) 473 hz
b) 376 hz
c) 485 hz
d) 533 hz
e) 547hz

Frequency will be 485 Hz

So option (c) will be the correct option

Explanation:

We have given frequency f = 500 Hz

Velocity of observer

Velocity of source

When both observer and source are moving then frequency is given by

, here v is the velocity of sound

So

So option (c) will be the correct option

explanation:

as the height from which the ruler was dropped increased, the speed of the ruler at ryan's hand increased.

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m
