Answer:
a. 20.01 km
b. 55.584 m/s
Explanation:
Assume there's no air resistance there. We can use the following equation of motion to calculate the distance traveled over t = 12 minutes (12 * 60 = 720 seconds):
And the speed with it hits the bottom
Answer:
P =
Explanation:
For this exercise we use that the pressure at a given level is the same, so we set a level on both sides of the pressure gauge, just the point where the liquid is on the system side, with a pressure (P)
P =
where is the atmospheric pressure in pascals, ρ the density of the liquid, g is related to gravity and h the height of the liquid from the marked reference.
It means the speed is constant with a value of 4 units.
Answer:
a monochromatic
Explanation:
because now you no need to worry about it and you can just answer in your paper
Answer:
=99.07nm
Explanation:
minimum thickness
2nd = (m - 1/2)λ
d = (m - 1/2)(λ/2n)
refractive index of the thin film, n = 1.34
minimum thickness m = 1
light wavelength λ = 531nm
d = (1 - 1/2) (531 / (2)(1.34)
d = 531/5.36
= 99.07nm
