Divide 3500km by 3h (according to the equation v = d/t) and you get 1167km/h.
Answer:
Explanation:
Assume the rod is horizontal
Sum vertical forces to zero
F - 8 - 4 - 2 - 3 = 0
F = 17 N
While this result answers precisely the question asked, it is not sufficient to guarantee equilibrium. We must also locate this force by summing moments to zero. Let's choose to sum about the left end.
8[9/2] + 4[1] + 2[6] + 3[4] - 17[x] = 0
x = 3.76470588...
the force must be supplied upward approximately 3.765 m from the left end
The rod does not actually have to be horizontal. Moment arms will all be proportionately reduced by tilting the bar from horizontal and the results will be identical. Assuming horizontal just reduces the calculation effort.
Emit greenhouse gases
Explanation:
Nuclear power is regarded as a clean energy source because it doesn't produce or emit greenhouse gases.
Greenhouse gases are mostly generated by the use of fossil fuels that pollutes the environment causing surging global temperature.
Nuclear power is produced by the splitting of radioactive minerals in rods. The process releases a large amount of energy. When the fuel elapses, only radioactive wastes remains.
There is no production of any greenhouse gas in the process of harnessing nuclear energy.
This is why it is considered a clean energy source.
