Answer:
When heat gets transferred through electromagnetic waves that move through space
.
Explanation:
Radiation is the propagation of energy in the form of electromagnetic waves or subatomic particles through a vacuum or a material medium.
The answer is Neon as the electron arrangement is 2,8. But for further learning, I just want to add that there are only 8 groups. The transition metals inbetween do not count as groups. If you look at a full periodic table the first two columns and the last six columns are the eight groups :)
Hope this helps :) ~
Answer:
The correct answer is - The net force is zero.
Explanation:
When an object moves on the surface with the same or constant acceleration which means there is no gain or loss of the speed it shows that all the forces of the object are at a point of zero.
If there would be any force applied on the object there must be some change in the velocity or acceleration but in this case there is no loss or gain of speed which means there is the object's net force is zero.
Therefore, option B is correct.
Explanation:
The heat generated when chemical, transport, or mechanical work is done by the organism is lost to the environment.
The the matter from one organism to the other is transferred via energy. The producer's produce and consumer's consume this energy according to 10% law. Most of the energy is lost (90% ) to the environment in form of heat.
