Ultraviolet Ray and red light sun sets on the horizon
Answer:
P₀ = 5.76 x 10⁻² MW
Explanation:
given,
efficiency of the power plant = 32%
Power produced by the nuclear fission = 0.18 MW
the power plant output = ?
using formula of efficiency

where P is the power produced in the power plant
P₀ is the power output of the power plant


P₀ = 0.18 x 0.32
P₀ = 0.0576 MW
P₀ = 5.76 x 10⁻² MW
Power plant output is equal to P₀ = 5.76 x 10⁻² MW
Answer:
Explanation:you must first make a free body diagram of the block to place all the forces that act on the block there. You will have four forces. The normal force, the weight, the horizontal force in x (which is what they ask to calculate) and the friction force. Then you raise the equations and you clear the values. I attach the solution.

The second mass is 
Now to obtain
we take moment about the edge of the platform

Substituting value


Answer:
Spot B & Spot C
Explanation:
They're closer to the equator and get more direct solar radiation, making them more likely to be where a warm air mass would form.
