I feel like you wouldn't be able to hear it. That is because sound waves need air to travel. Hope this helps!
Explanation:
The kinetic energy is basically the energy possesses by virtue of a body's motion
1. The truck moving to the quarry
let the mass be x
and the velocity is given as 20m/s
we know that the kinetic energy is given as
KE=1/2mv^2
KE=1/2(x)*20^2
KE=1/2(x)400
KE=200x
2. The truck leaving to the quarry
let the mass be 2x
and the velocity is given as 20m/s
we know that the kinetic energy is given as
KE=1/2mv^2
KE=1/2(2x)*20^2
KE=1/2(2x)400
KE=400x
From the analysis the kinetic energy is a function of mass, doubling the mass doubles the kinetic energy

Answer:
The wavelength is 503 nm
Explanation:
Considering constructive interference , this means that route(path) difference is equal to the product of order of fringe and wavelength of the light
i.e dsinθ = m
Where is the wavelength of light and m is the order of the fringe
Looking at θ to be very small , sin θ can be approximated to θ
and
Substituting this into the above equation
making x the subject
This above equation will give the value of the distance of the order fringe of the wavelength from the central fringe
Replacing with the value given in the question we have
= 710 nm m = 2 d =0.66 mm , l = 2.0 m
The separation of the second fringe from central maximum is 4,303 mm
To obtain the separation of the second order fringe of the unknown light from central maximum
Now to obtain the wavelength of this second source
from
Now substituting 3,053 mm for 2.0 mm for l , 0.66 mm for d and 2 for m in the above formula
