Answer:
a = 0.77 m/s^2
Explanation:
The centripetal acceleration is given as
The velocity of the car can be calculated using the circumference of the track and the period of the car.
So, the acceleration is

<h2>The option ( c ) is correct </h2>
Explanation:
As the frequency of oscillation of any oscillator is doubled
The velocity of sound v = νλ
here ν is the frequency and λ is the wavelength
Now if ν becomes double , the wavelength λ becomes one half . The velocity of sound remains the same in the same medium .
Thus option ( c ) is correct
