On the planet arrakis, an ornk is flying toward a fellow stationary ornk at 25 m/s while singing at a frequency of 1200 hz. if the second ornk hears a tone of 1240 hz, what is the speed of sound in the atmosphere of arrakis?

The speed of sound in the atmosphere of Arrakis is 775 m/s.

Explanation:

Given that,

Frequency f= 1200 Hz

Second frequency f' = 1240 Hz

Speed = 25 m/s

We need to calculate the speed of sound in the atmosphere of Arrakis

Using formula of frequency

Where, = speed of the sound

v = speed of the listener

Put the value into the formula

Hence, The speed of sound in the atmosphere of Arrakis is 775 m/s.

i believe the answer is a

answer: a) y=-8x+5

a) m= -8

b) m= -2

c) m= 7

d) m= 6
