Answer:
Explanation:
Spring has a tendency to store energy in them and deform its shape when force is applied on it. Once the applied force is removed it regains its original shape and size.
It is in helical shape and is used in mattress to give structure and support. Spring have elastic nature and follows spring forces, F = k * x
where is the applied force, k is the spring constant and x is the amount of extension.
When a heavier person sits on a mattress, more weight is applied on springs and they form coils, as weight is removed they regains its shape again.

Answer:
The Class E airspace extending upward from 700 ft or more above the surface and terminating at the base of the overlying controlled airspace.
Explanation:
The Class E airspace extending upward from 700 ft or more above the surface and terminating at the base of the overlying controlled airspace is defined as transition area.
In Class E, Instrument Flight Rules aircraft are controlled by Air Traffic Controller.
In the vast majority of areas, there are enough airports and victor airways to have Class E begin at 1,200 feet above ground level (AGL). This is known as enroute Class E airspace.
When all the lights are in series, and any one of them burns out
