Since f=m(v^2/r),or fnet is equal to ma.
force = unknown
velocity=22m/s
radius=75m
f=m(v^2/r)
f=925(22^2/75)
f=5969.333N
As the displacement of the maxima is calculated with the equation
(displacement)y=(m<span>λD)/slit separation (d)
halving the split separation doubles the displacement</span>
In physics, work output is the work done by a simple machine, compound machine, or any type of engine model. In common terms, it is the energy output, which for simple machines is always less than the energy input, even though the forces may be drastically different.
Answer:
5.42 meters
Explanation:
Sound intensity varies inversely with the square of distance:
I = k / r²
When r = 5, I = 100.
100 = k / 5²
k = 2500
I = 2500 / r²
When I = 85:
85 = 2500 / r²
r = 5.42
