What are the factors on which pressure exerted by liquids depends?
The factors on which pressure exerted by liquids depends are: 1. The density of the liquid 2. Acceleration due to gravity and 3. Depth of the point below the surface of the liquid.
The force exerted on a surface divided by the area over which the force is exerted?
Pressure is the force exerted on an object divided by the area where the pressure was applied.
State what is acceleration due to gravity?
On or near the surface of the earth, the acceleration of gravityis 9.8 meters (32.2 feet) per second2 in a vacuum.On or near the surface of other bodies, it's a different value, because their masses are different.Acceleration due to gravity is completely independent of the mass of the falling body. Whether the falling body has a large, small, or in-between mass, the acceleration due to gravity is the same number, as long as it stays on the same planet. Any difference is the result of air resistance.Ans 2The previous answer is a nice example of a newtonian constant gravity.Acceleration due to gravity is dependent on the mass and the distance between both bodies, bodies of relatively small mass have a negligible effect on the gravity exerted by large bodies. All bodies with mass have gravity. As the two bodies approach each other gravity increases as a square to their change in distance between their centers. The greater the mass of either body the greater the acceleration. dropping a bowling ball and a golf ball from a specific height they will strike the earth at the same time. But the gravity exerted by the sun on Venus is greater than the gravity exerted by the sun on the Earth due to the relative distances between them. The gravity exerted on the Earth by the sun is greater than the gravity exerted by the sun on the moon due to the relative difference in mass of the earth and the moon.Gravity is proportional to the product of the two masses, and inversely proportional to the square of the distance.Read more: Does_the_mass_and_gravity_correlate
Is The pressure exerted on an object by a fluid always parallel to the surface of the object?
No. It is not.
What is the gravity percentage on Mars?
Martian gravity is only 38% of the Earth's gravity.
How much does something weigh 1000 meters above earths surface?
"at an altitude of 400 kilometres (250 miles), equivalent to a typical orbit of the Space Shuttle, gravity is still nearly 90% as strong as at the Earth's surface" -- Wikipedia: Earth's gravity # Altitude
What are examples of force being exerted?
Two examples of force being exerted include gravitational and electromagnetic. A body of mass rested on a surface is being held there by the Earth's force of gravity.
Does earth have stronger or weaker gravity than mars?
The gravitational force exerted at the surface (and above the surface) of Mars is weaker than that here on Earth. The reason: Mars has less mass than earth.
In which direction is pressure exerted in a fluid at rest?
If its in a container, pressure is downward and outward due to gravity and confinement respectively. If its on a flat surface without confinement, the pressure is exerted downwards on the surface and the boundaries are held by a combination of adhesion and cohesion.
Can humans visit neutron stars?
No. The tidal forces exerted by a neutron star's gravity would tear a person apart before they could reach the surface. On the surface gravity is so great that even atoms are crushed into a degenerate state. The surface is also extremely hot.
How does acceleration due to gravity changes with altitude?
The acceleration of gravity ... on or near the Earth, for example ... is inversely proportional to the square of the distance from the center of the Earth. So it diminishes as you rise from the surface. When you have ascended to an altitude of one Earth radius ... about 4,000 miles ... your distance from the center is then two Earth radii, so the acceleration of gravity has shrunk to 1/4 of its value on the surface.
What are the factors on which pressure exerted by liquids depends?
The factors on which pressure exerted by liquids depends are: 1. The density of the liquid 2. Acceleration due to gravity and 3. Depth of the point below the surface of the liquid.
What is the force exerted on a surface divided by the tota larea over which the force is exerted?
That's the average 'pressure' on the surface.
How is air pressure effected by altitude?
With a higher altitude, there is a lower air pressure. This is caused by gravity pulling the gas molecules of our atmosphere closer to its surface. when the molecules are farther away from the Earth's surface the gravitational pull is weaker thus making the atmosphere thinner higher up and thicker closer to the surface.
How is an aeroplane able to stay in the air if it is heavier than air?
Yes, as long as the surface area of the airplane was large enough to make the force of air resistance balance with the force of gravity or if the airplane is moving at a fast enough speed to make the air resistance balance with gravity.
What is a force exerted on a surface divided by the total area over which the force is exerted?

How do you call the force exerted on a surface divided by the area over which the force is exerted?
