Answer:
The answer is a wedge.
Explanation:
The wedge is a combination of two inclined planes. It is used to separate bodies which are held together by large forces, e.g, splitting timber
M.A.= slant height of wedge/thickness of wedge.
Hence a long thin wedge has a higher mechanical advantage than a short thick one; or the smaller the angle theta between the slant heights, the greater the mechanical advantage.
The pressure is the ratio between the force and the area the force is excerted on.
Assuming that the two cubes are identical, they have the same surface area S, and the same weight force F.
So, at the beginning, you have a force of 2F over an area of 2S.
After you remove one cube, you have a force of F over an area of S.
The pressure doesn't change:
Potential energy (Ep) is equal to the mass (m) of the subject multiplied by the height (h) from sea level that its positioned multiplied by the earth acceleration (g).
Ep = mgh
In your case m = 70 kg, g = 9.8m/s^2 , h = 3m , all the units are in SI, so simple multiplication gives Ep = 2060 J or Nm^2
Answer:
The rotation rate of the mercury are determined by the radar used by the scientists. The reflected beam of the radar are showed by the doppler broadening. The rotational period of the mercury on its axis are rotates slow as compared to orbital period.
Basically, the rotational period of the mercury takes 59 earth days to rotate about its axis.
