Answer:
0.368 cm
Explanation:
x = distance by which the mercury rise
d = depth of the water = 10 cm = 0.10 m
ρ = density of water = 1000 kgm⁻³
ρ' = density of mercury = 13600 kgm⁻³
P₀ = atmospheric pressure
Using equilibrium of pressure on both side
P₀ + ρ g d = P₀ + ρ' g (2x)
(1000) (0.10) = (13600) (2x)
x = 0.00368 m
x = 0.368 cm

Hello There
Answer: The Doppler effect
Reason: The Doppler effect is an increase or decrease in the frequency of sound, light, or waves as the source and observer move to each other. An example would be a firetruck with its siren on driving away from you.
I hope this helps

The force between two poles is given by the formula:
F=mi*q1*q2/4*pi*r
where
F is force in newtons
q1 and q2 are magnitudes of the two poles
mi is <span>the </span>permeability<span> of the</span> medium
r is the distance between the poles
According to this formula the following statement is true:
The force between two poles is proportional to <span>the inverse square of the distance between the poles.</span>
