Who exerts more pressure on the ground- a 50-kg woman standing in high heels, or a 50-kg woman standing in work boots? The 50-kg woman standing in high heels. How do fluids exert pressure? All of the fluids exerted by the individual particles in a fluid combine to make up the pressure exerted by the fluid.
Who exerts more pressure on the ground?
Solution: Pressure is inversely proportional to area . While walking, one foot is in contact with the floor and while standing both feet are on the floor. Therefore pressure exerted while standing is less than the pressure exerted while walking.
When you stand on one foot instead of two the pressure you exert on the ground is *?
When we stand on one foot because on both feet the area increases and pressure is inversely proportional to area. So, pressure decreases on both feet .
Which two factors affect the amount of pressure acting on an object?
As such, pressure depends on the amount of gas (in number of molecules), its temperature, and the volume of the container .
Does the buoyant force on a submerged object depend on the weight of the object?
Buoyant force has NO dependency on the weight of the object itself. It does depend on the volume of the object , but that is because the volume of the object will be the same as the volume of liquid displaced. If either weight density or volume is increased, the buoyant force will increase by that same factor.
How do you calculate the pressure you exert on the ground?
Average ground pressure can be calculated using the standard formula for average pressure: P = F/A . In an idealized case, i.e. a static, uniform net force normal to level ground, this is simply the object’s weight divided by contact area.
What is the ground pressure of a human?
As we have demonstrated, adult humans have a foot pressure between 2.5 lbs/in2 and 3.5 lbs/in2 . A 6 year-old boy has a weight of 75 pounds while each foot has a surface area of 16 in2.
Where is fluid pressure greatest?
Where is fluid pressure greatest? 2 meters below the surface of a swimming pool .
How do u calculate pressure?
- To calculate pressure, you need to know two things:
- Pressure is calculated using this equation:
- pressure = force ÷ area.
Who will exert more pressure a boy standing on one leg and another boy standing on two legs?
Pressure is inversely proportional to area . So when we stand on two legs, the area becomes larger and the pressure decreases.
What is the relation between pressure force and area?
Answer: Pressure is directly proportional to force and inversely proportional to area . Explanation: Pressure is defined as the ratio of force applied to the area of cross section.
What do you mean by 1 pascal of pressure?
A pascal is a pressure of one newton per square metre , or, in SI base units, one kilogram per metre per second squared. ... For example, standard atmospheric pressure (or 1 atm) is defined as 101.325 kPa. The millibar, a unit of air pressure often used in meteorology, is equal to 100 Pa.
What is the relation between pressure and density?
Density and pressure/temperature
Density is directly proportional to pressure and indirectly proportional to temperature . As pressure increases, with temperature constant, density increases. Conversely when temperature increases, with pressure constant, density decreases.
What 2 forces must be balanced for an object to float?
To float, the weight force on an object must be balanced by the upward push by the water on the object . The amount of material and the type of material that makes up the object affects the size of the weight force on the object.
Is buoyant force equal to weight of object?
Archimedes’ principle is the statement that the buoyant force on an object is equal to the weight of the fluid displaced by the object . ... If you want to know the buoyant force on an object, you only need to determine the weight of the fluid displaced by the object.
What happens if the buoyant force is less than the weight of an object?
If the buoyant force is less than the object’s weight, the object will sink . If the buoyant force equals the object’s weight, the object will remain suspended at that depth. The buoyant force is always present in a fluid, whether an object floats, sinks or remains suspended.
