Adiver bounces straight up from a diving board, avoiding the diving board on the way down, and falls feet first into a pool. she starts with a velocity of 4.00 m/s and her takeoff point is 1.80 m above the pool. what is her highest point, in meters, above the board?

0.81549 m

Explanation:

t = Time taken by the diver

u = Initial velocity of the diver = 4 m/s

v = Final velocity of the diver

s = Displacement of the diver

a = Acceleration due to gravity = 9.81 m/s²

Equation of motion

a) Her highest height above the board is 0.81549 m

answer: i'm not sure which is which for i get confused on it all the time but i can tell you that the answer lies with the convex and concave devices. i hope this you. have a good day and best of luck to you!

explanation:

scattering of light by tiny particles in air to produce the colors we see on sky, is dependent on the following factors:

(i) wavelength of light

(ii) size of the scattering particle  

(iii) distance traveled by light through the atmosphere.

according to rayleigh's law of scattering, the amount of scattering is inversely proportional to the fourth power of its wavelength. shorter the wavelength, greater is its scattering. hence violet/blue light is scattered more than red.

sun's light is a composite light ( visible light) with wavelengths in the range 400 nm (violet) to 700 nm (red). as sunlight passes through our atmosphere, the molecules of air scatter light according to their wavelengths. during sunrise and sunset, the sun's position is below the horizon. hence light from the sun travels a greater distance in the atmosphere when compared to its position a noon.

as sunlight enters the earth's atmosphere, blue light is scattered away and at the end of its journey in the sky, only red and orange wavelengths remain in the beam.

hence at sunrise and sunset, the sky appears reddish orange.
