Solution :
Given data is :
Density of the milk in the tank, 
Length of the tank, x = 9 m
Height of the tank, z = 3 m
Acceleration of the tank, 
Therefore, the pressure difference between the two points is given by :
Since the tank is completely filled with milk, the vertical acceleration is 
Therefore substituting, we get
Therefore the maximum pressure difference in the tank is Δp = 47.87 kPa and is located at the bottom of the tank.
Answer:
1.414
Explanation:
Snell's law states:
n₁ sin θ₁ = n₂ sin θ₂
where n is the index of refraction and θ is the angle of incidence (relative to the normal).
The index of refraction of air is approximately 1. So:
1 sin 45° = n sin 30°
n = sin 45° / sin 30°
n = 1.414
Round as needed.

27.5 because of you divide the 55miles with the time you get your velocity which is the speed.
Answer:
Explanation:
The energy of a single photon is given by:
where
h is the Planck constant
c is the speed of light
is the wavelength
For the photon in this problem,
So, its energy is
One mole of photons contains a number of photons equal to Avogadro number:
So, the total energy of one mole of photons is
