A. atoms fuse in the sun, but atoms break up in nuclear power plants.
The process in the Sun is a Fusion Process, atoms are fused, while the process in nuclear power plant is a Fission Process, atoms break up.
Magnetism is <span>a physical phenomenon produced by the motion of electric charge, resulting in attractive and repulsive forces between objects.</span>
Answer:
Explanation:
<u>Gravitational Potential Energy</u>
It's the capacity of an object to do work due to its relative height from a fixed reference point.
It's computed as
GPE=m.g.h
Where m is the mass of the object, h is its height and g is the acceleration of gravity, 
The mass of water is given as
The height above the rocks is h=50 m. Let's compute the GPE
It should be expressed in scientific notation
The GPE at the bottom, where h=0
The change of gravitational potential energy is:
Answer:
is a reflection.
The image is real light rays actually focus at the image location). As the object moves towards the mirror the image location moves further away from the mirror and the image size grows (but the image is still inverted). When the object is that the focal point, the image is at infinity.
Explanation:
The answer is D, or Outer Space.
Explanation:
Sound is implemented through mechanical wave transferral, which requires a medium (solid, liquid, or gas) to travel through. Because sound is a mechanical wave, it cannot travel through vacuums (space).
