What would happen to the atmospheric pressure at the ground if the earth's gravitational force were to increase?
If the Earth's gravitational force were to increase, the atmospheric pressure at the ground would also increase. This is because the increased gravitational force would cause more air molecules to be pulled towards the Earth's surface, resulting in higher atmospheric pressure.
What else can I help you with?
Ignoring air resistance what is the minimum initial speed a projectile must have at the Earths surface if the projectile is to escape the Earths gravitational pull?
The minimum initial speed for a projectile to escape Earth's gravitational pull (escape velocity) is about 11.2 km/s. This speed is independent of the mass of the projectile and is based on the balance between the projectile's kinetic energy and gravitational potential energy. Any speed greater than the escape velocity will allow the projectile to escape Earth's gravitational pull.
What is stronger than earths gravity?
The gravity of a black hole is stronger than Earth's gravity. Black holes have such a strong gravitational pull that not even light can escape from them.
What is earth gravity in decimals?
There is no fixed figure for earths gravity.The effect of earths mass (or gravity) depends on its mass and how close you are to it.the gravitational force (f) on an object (by the earths gravity) can be calculated by:.f (newtons) = (G * m1 * m2) / d^2.key:m1 = earths mass (5.974 * 10^24 kg)m2 = objects mass (kg)d = distance between their centres of gravity (metres)G = newtons gravitational constant (6.672 * 10^-11).notes:the force on the object is equal to the reaction force on the earth.
What effect does Earths gravitational force on objects of different masses?
The gravitational force of Earth affects different masses in the same way by pulling them towards the center of the Earth with a force proportional to their mass. This means that objects of different masses will accelerate at the same rate towards the Earth due to gravity.
What is the potential energy dependant upon an objects weight and distance from earths surface?
The potential energy of an object is dependent on its weight and its distance from Earth's surface due to the gravitational force acting on it. The formula for gravitational potential energy is given by PE = mgh, where m is the mass of the object, g is the acceleration due to gravity, and h is the height of the object from the reference point.
Which two inner planets have atmospheres that consist of mostly carbon dioxide?
Venus and Mars. The difference is that Venus atmospheric pressure is around 93 times that of Earths, while Mars' atmospheric pressure is only 0.7% of Earths.
The atmospheric pressure near the earths surface does what?
It decreases as you move away from the earth surface
Dose air in the atmosphere exert pressure on earths surface?
Yes. Atmospheric pressure is the pressure caused by air when it exerts pressure on the surface of earth.
Does pressure increase from earths surface toward the center of earth?
Yes.
What causes the pressure of the atmosphere?
Atmospheric pressure is caused by the force of the air above the earths surface. It is measured by the point in which the air meets the atmosphere.
How is pressure measured with a barometer?
by the earths gravitational pull the barometer can measure the amount of air pressure in the air, also because of carbons gases
What is barometric pressure measured by?
A barometer measures atmospheric pressure to determine weather or altitude changes.
Does pressure and temperature increase or decrease with depth below earths surface?
it increases
What planets air pressure is the same as it is 30 km above earths surface?
The planet with an atmospheric pressure similar to that 30 km above Earth's surface is Venus. At an altitude of about 50 km above Venus, the atmospheric pressure is comparable to Earth's surface pressure.
What is the average psi on the earths crust?
Standard atmospheric pressure at sea level is about 14.7 PSI. So, then what is the pressure at about 5,645 feet below the surface of the earth?
If iron melts at 1538 degrees and the earths core is at 5500 degrees why is it still a solid?
the 2 main variables which decide whether an element or compound is a solid, liquid, or gas, are temperature and pressure.Iron melts at 1538 degrees only when it is pure (which the core is not) and under atmospheric pressure. The iron in the earths inner core is under pressure equivalent to many thousands (if not millions) times that of atmospheric pressure, so it exists as a solid.
what main factors cause the air in earths atmosphere to move?
uneven heating by the sun causes changes of atmospheric pressure, and winds blow from regions with high pressure to those with low pressure.
