Answer:
Between 590 and 750 nm
Explanation:
When you look at someone's red shirt, for instance, that shirt will be absorbing or scattering wavelengths of light lower than 590 nm, so those waves will not reach your eyes. But a red shirt will be reflecting some wavelength between 590 and 750 nm, which your eyes process as red.
You have a speed and a direction.
That gives you the wind's 'velocity'.
Newton’s Thrid Law, which states that for every reaction there is an opposite reaction.

Explanation:
F = normal force by each board on each side
W = weight of the board in between acting in down direction = 95.5 N
f = frictional force in upward direction by each board
= coefficient of friction = 0.663
Using equilibrium of force in Upward direction
f + f = W
f = W/2
f = 95.5/2 = 47.75 N
frictional force is given as
f = F
47.75 = (0.663) F
F = 72.02 N
