0.6944 m/sec^2
Explanation:
The computation of the average acceleration is given below:
a = v - u ÷ t
where
a denotes average acceleration
v denotes final velocity
u denotes initial velocity
t denotes time
So, the average acceleration is
= (25 - 0) ÷ 10
= 0.6944 m/sec^2

The value is
Explanation:
From the question we are told that
The frequency of the second player is
The beat frequency is
The speed of sound is
Generally the frequency of the note played by the first player is mathematically represented as
=>
=>
From the relation of Doppler Shift we have that
Here
So
=>
