Answer:
Explanation:
In space, rockets zoom around with no air to push against. ... When a rocket shoots fuel out one end, this propels the rocket forward — no air is required. NASA says this principle is easy to observe on Earth. If you stand on a skateboard and throw a bowling ball forward, that force will push you and the skateboard back.
Answer:
No they just orbit the sun
Explanation:
<h2><u>
Answer</u>
:</h2>
Distance = 50m
Displacement = 50m to the right
<h2><u>
Explanation</u>
:</h2>
<em>Distance</em> is the total length of a given path. It is a scalar quantity and thus takes no consideration on the direction of the path.
<em>Displacement</em> on the other hand is the change in position of an object. It is a vector quantity and takes consideration on the direction of the object.
From the question:
<em>The swimmer swims half lap by moving from the left end to the right end of a pool that is 50m long.</em>
Distance = total length of the given path = 50m
Displacement = change in position of the swimmer from the left end (0m) to the right end (50m) = 50 - 0 = 50m
Since direction is important in displacement, the complete details of the displacement should be 50m to the right
It's not the electricity. It's how we produce it.
Solar panels, wind turbines, nuclear reactors, and water wheels can be used to produce electricity with no effect on climate.
Coal, oil, wood, gasoline, natural gas, household trash, and tall dry grass can be burned to boil water to make steam to turn a generator and make electricity. When everybody does that, the burning releases enough Carbon Dioxide into the atmosphere to futz up the Earth's climates. That's exactly what we have done for the past 200 years.
