What else can I help you with?
Why a nail has a pointed tip?
the tip of a nail is kept pointed by keeping in mind the principle that pressure is inversely proportionate to the area in contact. The pointed tip covers a less area, further creating a situation of more pressure, so that we could easily pierce it through the wall.
Does air exert any pressure?
There is about 2 ton of air on every square foot of the Earth (less at high altitudes)
A faster-moving fluid exerts less pressure than a slower-moving fluid true or false?
False. According to Bernoulli's principle, faster-moving fluids exert less pressure compared to slower-moving fluids. This is because faster-moving fluids have lower internal energy and therefore exert less pressure.
Is the pressure exerted by different gases different?
Yes, the pressure exerted by different gases can be different, as it depends on factors such as the number of gas molecules, temperature, and volume. However, if the gases are in the same container at the same temperature, they will exert the same pressure.
Why would a denser fluid exert stronger pressure on an object in the fluid than a less dense fluid would?
A denser fluid would exert stronger pressure on an object in the fluid than a less dense fluid would because of the pressure differences. A denser fluid would have a greater pressure difference, therefore greater buoyancy, and exerting stronger pressure on the object.
Air pressure decreases the higher you go?
Definitely. P = Density * gravity * Height The more ascend, the less air will remain on top of you. In other words there are less air to exert pressure on you. Therefore, pressure will go down. Check this out: http://www.engineeringtoolbox.com/air-altitude-pressure-d_462.html
What is the difference between altitude and air pressure?
Air pressure is the amount of pressure exerted by Earth's atmosphere in a specific place, while altitude is the vertical distance of an object or place from sea level. Air pressure decreases as altitude increases, since there is less atmosphere to exert pressure.
Why does Bernoulli's principle explain the relationship between the speed of a fluid and its pressure?
Bernoulli's principle explains that as the speed of a fluid increases, its pressure decreases. This is because the faster-moving fluid particles have less time to exert pressure on the surrounding surfaces, resulting in lower pressure.
Do you exert more force when you are closer to the fulcrum?
do you exert more force when you are further from the fulcrum
Is the vapor pressure of water lower at higher altitude?
Yes, the vapor pressure of water is lower at higher altitudes due to the reduced atmospheric pressure. As altitude increases, the fewer molecules in the air exert less pressure on the water's surface, causing it to evaporate more slowly.
Why are airplanes shaped with a pointed nose?
A pointed nose is less wind resistant.
Why does a nail has pointed tip?
the tip of a nail is kept pointed by keeping in mind the principle that pressure is inversely proportionate to the area in contact. The pointed tip covers a less area, further creating a situation of more pressure, so that we could easily pierce it through the wall.
