The answer is solar flare. Solar flares are commonly accompanied by coronal mass ejection. Solar flares are periods when the sun is suddenly brighter at a spot at its surface. This is due to the ejection of electrons, ions, and atoms (plasma clouds) accompanied by electromagnetic waves.
Answer:
A-the energy of the wave decreases gradually
Explanation:
when a wave is acted upon by an external damping force the energy of the wave decreases gradually.
The energy degrades into the form of heat which is considered to be of less value and use. The reason is because it disperses and spreads more widely.
So therefore it end up as heat with a little sound but that is close to none because that too disperses into heat i.e. decreased form of energy.
Answer:
22050 J
Explanation:
Given Mass of the ball, m = 4.5 Kg
Height, h =500 m
Acceleration due to gravity, 
To calculate the potential energy we use formula,
Substituting the given values, we get
PE = 4.5× 9.8×500
=22050 J
I am not 100% sure on this, but I would have to say A or D. I am sorry I could not give you a definitive answer but there you go!
Answer:
The electron affinity of an atom or molecule is defined as the amount of energy released when an electron is attached to a neutral atom or molecule in the gaseous state to form a negative ion.
