Answer:
Is Mercury an answer on your thing?
Explanation:
Mercury has the least amount of gravity, so therefore you can jump the highest on Mercury.
Answer:
7.3cm above the compressed spring.
Explanation:
We can use the conservation energy theorem to solve this problem:

The block was dropped 7.3cm above the compressed spring.
Answer:
It is the area on opposite side of the earth from an earthquake where no s waves are picked up by seismographs.
Explanation:
Shadow zone of an earthquake is one which is farthest from the epicenter. Hence it is not the area closest to earthquake.
In shadow zone only the S waves are stopped by whereas P waves through refracted, travel through and are measured in seismograph. Hence it is an area where there are few seismographs.
The zone is not constant and each epicenter has its own shadow zone. The shadow zone was caused by the inability of s waves to pass through the liquids. This proved the presence of liquid layer in earth's core. Hence the shadow zone is not the outer molten core of earth but the zone was caused by the molten core.
Hence the shadow zone of an earth quake is the area on opposite side of the earth from an earthquake where no s waves are picked up by seismographs.
Answer:
By teh way is isn't it question of law or science and the picture is of what electric light or not I have read it so I was asking isn't is question of science
Answer:
critical angle is the angle of incidence in optically denser medium, for which the angle of reflection in the less denser medium is 90 degree
Explanation:
total internal reflection occurs at one particular angle of incidence where the reflected ray lies on the boundary.
this angle is called the critical angle
