It is D,Copernicus.when he first proposed the idea everyone thought he was nuts and that it was not plausible.even though his theory wasn't so accurate it still helped further scientific research.HE was born February 19,1473 and he published a book about his theory.
Hello!
Most ocean waves obtain their energy and motion from the wind.
Ocean waves are surface waves that move across the surface of the ocean. When wind touches the surface of the water, there is friction in the contact zone. This friction causes a drag effect, that makes wrinkles on the surface of the water. As the wrinkles get bigger, they transform into full-blown waves, and the taller the wave, the more energy it can extract from the wind, making them even bigger and to move longer distances.
Have a nice day!
Answer:
R= 602 .11 N
Explanation:
The horizontal component of tension T will give reaction of the wall and the vertical component of T will balance the weight of of the climber .
T cos32 = R
710 x .848 = R
R= 602 .11 N .
Answer:
A non-contact force is a force which acts on an object without coming physically in contact with it.
Explanation:
For example:
<em>Gravitational force.</em>
<em>Magnetic force.</em>
<em>Electrostatics.</em>
<em>Nuclear force.</em>
The correct answer is :
<span>D If the radiation were to leak out of the reactors, it could cause significant damage to living organisms.

In fact, the ionizing radiation that leaks out from a nuclear reactor is able to modify the DNA of the cells of living organisms, causing mutations and/or diseases like cancer.</span>
