To solve this problem it is necessary to apply the concepts related to pressure as a unit that measures the force applied in a specific area as well as pressure as a measurement of the density of the liquid to which it is subjected, its depth and the respective gravity.
The two definitions of pressure can be enclosed under the following equations
Where
F= Force
A = Area
Where,
Density
g = Gravity
h = Height
Our values are given as,
If we make a comparison between the lid and the tube, the diameter of the tube becomes negligible.
Matching the two previous expressions we have to
Re-arrange to find h
Therefore the height of water in the tube is 7.9cm
Evan could also grow some plants in the light? I don't have a clue but that would be my guess :) No points needed
Answer:
a) transferring energy
Explanation:
A linkage is an assembly of parts connected together to control forces and movement. The connections between links are called joints and are used for ensuring movement, pure rotation or sliding.
Linkages provides a means in which kinetic energy is being transferred in different directions within a system. This Linkages can be used to Change force direction, size of force applied or the motion created by the force.
You have the correct formula. Work = F d .
You use it by gathering up 'F' and 'd' and throwing away everything else.
F = 599.79 N
d = 153 cm
That's all you need to calculate 'W' with your formula. Just because they
also gave you the mass and the time doesn't mean you MUST use them.
My guess is that there are more parts to this problem where you may need
the mass and the time. For example, if they ask you for the power, then
you'll need to divide the work by the time.
