If an object is moving with a constant velocity, then by definition it has zero acceleration. So there is no net force acting on the object. The total work done on the object is thus 0 (that's not to say that there isn't work done by individual forces on the object, but the sum is 0 ).
Below are the benefits <span>of using nuclear power plants to generate electricity:
</span><span>Nuclear power plants use simple power plant designs not vulnerable to human error or natural disasters.
</span>
<span>Nuclear power plants use renewable fuel.
</span>
<span>Nuclear power plants produce a large amount of energy for a small mass of fuel. Nuclear power plants produce no toxic waste products.

- The outflows of nursery gasses and in this manner the commitment of atomic power plants to an Earth-wide temperature boost is accordingly moderately little. The era of power through atomic vitality lessens the measure of vitality produced from non-renewable energy sources (coal and oil). Less utilization of petroleum products implies bringing down ozone-depleting substance outflows (CO2 and others).

If he dropped them both at the same time, then as close as anyone could tell, they both hit the ground at the same time.
Answer:
13.5 ms
Explanation:
The sound wave travels with uniform motion in both cases, so the time taken to cover a distance d is given by:
where
d is the distance to cover
v = 340 m/s is the speed of sound in air
So for the people across the newsroom,
d = 4.7 m
So the time taken is
The radio waves instead travels with uniform motion at the speed of light:
So the time taken for them is
where
d = 82 km = 82,000 m
is the distance of the people who are 82 km away. Substituting,
Therefore, the difference in time is
Faraday's law is
<span>∈ </span><span>= −N [(<span><span>d<span>ϕB)/(</span></span><span>dt)]
</span></span></span>where N is the number of turns, <span>ϕB</span> is the magnetic flux, and t<span> is time.</span>
