Answer:23 seconds

Explanation:

Acceleration(a)=3.87m/s^2

distance(d)=1020m

Initial velocity(u)=0

d=uxt + (axt^2)/2

1020=0xt + (3.87xt^2)/2

1020=(3.87xt^2)/2

Cross multiply

1020x2=3.87xt^2

2040=3.87xt^2

t^2=2040/3.87

t^2=527.13

t=22.95

Time(t) is approximately 23seconds

Rainbow [258]

Answer:

786 Hz

Explanation:

Recall, the speed of sound is

v = 332 + 0.6t

Where t = 23°

v = 332 + 0.6(23)

v = 332 + 13.8

v = 345.8 m

Also, it is known that distance between two consecutive resonance length is half of the wavelength.

L2 - L1 = λ/2

34 - 12 = λ/2

λ/2 = 22

λ = 44 cm

Finally, remember that also

Frequency = speed/ wavelength

Frequency = 345.8/0.4

Frequency = 786 Hz

Therefore, the frequency of the tuning fork is 786 Hz
