Answer:
Explanation:
As we know that work done by electric force is given as
so here we know that charge is moving from
to another position
so we will have
Which layer of the atmoshere is the top layer of the thermoshere
2 answers:
Answer:
The answer is Exosphere.
Explanation:
Firstly, a brief denition of thermosphere:
The thermosphere is a layer of Earth's atmosphere. The thermosphere is directly above the mesosphere and below the exosphere. It extends from about 80 km to between 600 and 800 km above our planet.
The thermosphere is typically about 200° C (360° F) hotter in the daytime than at night, and roughly 500° C (900° F) hotter when the Sun is very active than at other times.
I have attached an image that shows the atmosphere layers
Finally, the top layer of the thermosphere is Exosphere.

Answer
To understand this concept it is necessary to understand Newton's Second Law
According to Newtons Second law applied force is equal to rate of change of momentum of a body.
Mathematically,
here, is rate of change of momentum with respect to time
It means If two eggs fall from same height,one on softer surface and other on hard surface that time the momentum of both eggs will remain equal at both the surfaces. But, impact time will be different. On hard surface egg will stop almost instantly so impact time will be small and hence the force on egg will be large therefore the egg will breakup.
On the other hand on the soft surface like a cotton, egg will not stop instantly but it will slow down for a few seconds and then stop due to which the time of impact will increase. Therefore the force on egg will be less and it won't break up.
