What is the force that acts over a certain area?
A pressure, its units are Force/Unit area
O calculate pressure it is necessary to know the force and what?
the area over which the force acts
When a force Of 1N acts perpenticularly on an area of 1m the pressure is?
1 m is not an area.
Is pressure the amount of force that acts on a given area of an object?
YES
What do you do to increase the amount of pressure by whwere the force is applied?
Since Pressure is Force per Unit Area (P = F/A), there are intuitively two ways to increase pressure. You can either keep the area constant and increase the force being applied, or keep the force constant and decrease the area on which the force acts.
How is pressure related to the area over which force acts?
The area over which a force acts, is proportional to the pressure. When the area is large then, the pressure acted on it is also large, so the force is greater.
What is the force that acts over a certain area?
A pressure, its units are Force/Unit area
Pressure is a force defined as?
Pressure is a force defined as a push that acts over a certain area.
O calculate pressure it is necessary to know the force and what?
the area over which the force acts
When a force Of 1N acts perpenticularly on an area of 1m the pressure is?
1 m is not an area.
Is pressure the amount of force that acts on a given area of an object?
YES
A force of 1000n is exerted on piston 1 what will be exerted on piston 2?
If this is about a hydraulic system, same pressure acts through out the fluid. Take, A = cross sectional area (area normal to force) of piston 1 B = "" "" "" of piston 2 F2 = Force on 2nd piston So, pressure = 1000/A = F/B Therefore, F = (1000 X B/A ) N (The force depends on the area ratio)
Describe cell volume cell surface area ratio of surface area to volume?
Look in the book broseff.
Is less pressure produced by decreasing the area a force acts on?
No. The opposite is true.
How does surface area describe a cell?
Surface area of cell is divided volume of cell to get surface to volume ratio . If surface area is 8 cm2 and volume is 2 cm2 . The ratio would be 4:1 .
What is the relationship between area and pressure of a constant force?
The area over which a force acts, is proportional to the pressure. When the area is large then, the pressure acted on it is also large, so the force is greater.
What word expression describe how to calculate pressure?
Force Divided by area
