Answer:
Explanation:
Givens
vi = 0
a = 9.81
d = 4.50 m
vf = ?
Formula
vf^2 = vi^2 + 2 * a * d
Solution
Substitute the knowns into the formula
vf^2 =0 + 2 * 9.81 * 4.50
vf^2 = 88.29 Take the square root of both sides.
sqrt(vf^2) = sqrt(88.29)
vf = 9.40 m/s
Beta Carotene is the reason why a carrot is orange. Carotene is a color pigment that is found in large quantities in carrots and it has health benefits as well. The main health benefit of carotene is that our body converts it into vitamin A which is essential.
Polarization of light is achieved by passing the light through a polarizer which causes the light to vibrate in only one direction.
<h3>What is polarization of light?</h3>
The question is unclear but I will try to explain what is meant by polarization of light. We know that light is an electromagetic wave and vibrates in all directions.
The polarization of light enables light to vibrate in a specified direction. This is achieved by passing the light through a polarizer which causes the light to vibrate in only one direction.

The photon
energy is the energy carried by a single proton.
The equation used for calculating photon energy is:
E = hc / λ
where h = Planck constant
c = speed of light and
λ = wavelength of photon
frequency = f = c / λ
replace c /λ with f in the equation of photon energy
E = hf
frequency = 610 thz = 6.1 x 10¹⁴hz
h = 6.26 x 10⁻³⁴ js
E = 6.26 x 10⁻³⁴ x 6.1 x 10¹⁴
<span>E = 3.8 x
10</span>⁻¹⁹ j
