Answer:
Radiation
Explanation:
The heat transfer take place by three modes
1. Conduction
This type of heat transfer take place in the solid materials like metals .This heat transfer take place due to vibration of electron.
2.Convection
This type of heat transfer take place in the moving fluid like water ,air etc.
3.Radiation
Every materials which having temperature above 0 K are emitting radiation.This type of heat transfer dominate at the high temperature.
We know that temperature of sun is so high so the heat transfer from sun to the earth is take place by radiation mainly.
Answer:
Explanation:
The sound moves in the form of waves. The amplitude is the distance between the highest and the lowest point of a wave. In this way the amplitude indicates the amount of energy that a sound signal contains.
Intensity is the amount of acoustic energy that a sound contains. Intensity is measured in decibels. Volume is a measure of the energy that a signal carries, being a magnitude of intensity.
In this way it is possible to say that the energy of a signal is closely related to its amplitude, but its development over time is also important.
The tone or height is the quality that distinguishes between a high or low sound and a low or high sound.
The correct answer is - c. escape.
The word ''escape'' means to get away from something. This word can be used for multiple different situations, and it can refer to both physical and psychological matters.
In a physical sense it can be used to escape from certain unpleasant, or dangerous situation. Example: I have to escape from this prison.
In a psychological sense it can be used to escape, move away, from a certain state of mind. Example: I have to find an escape from my depressive thoughts.
I believe it’s self-referent encoding
The second stone hits the ground exactly one second after the first.
The distance traveled by each stone down the cliff is calculated using second kinematic equation;
where;
- <em>t is the time of motion </em>
- <em />
<em> is the initial vertical velocity of the stone = 0</em>
The time taken by the first stone to hit the ground is calculated as;
When compared to the first stone, the time taken by the second stone to hit the ground after 1 second it was released is calculated as
Thus, we can conclude that the second stone hits the ground exactly one second after the first.
"<em>Your question is not complete, it seems be missing the following information;"</em>
A. The second stone hits the ground exactly one second after the first.
B. The second stone hits the ground less than one second after the first
C. The second stone hits the ground more than one second after the first.
D. The second stone hits the ground at the same time as the first.
