Where the value of g is maximum?

Note: The acceleration due to gravity is maximum at poles because the poles are near to the centre of mass of the earth. And the equator is somewhere far away from the centre of mass of the earth.

In this regard, What happens to pressure as altitude increases?

As altitude rises, air pressure drops. In other words, if the indicated altitude is high, the air pressure is low. … As altitude increases, the amount of gas molecules in the air decreases—the air becomes less dense than air nearer to sea level.

Regarding this, What is value of g?

Its value is 9.8 m/s2 on Earth. That is to say, the acceleration of gravity on the surface of the earth at sea level is 9.8 m/s2. When discussing the acceleration of gravity, it was mentioned that the value of g is dependent upon location.

Beside above, Where the value of g is maximum and minimum?

The value of acceleration due to gravity is maximum at poles and minimum at the equator. The acceleration of gravity of an object is a measurable quantity. From Newton’s universal law of gravitation, its value depends on the mass of the Earth and the distance the object is from the Earth’s centre.

Where is the value of g equal to zero on Earth? Since, mass m of an object can never be 0. Therefore, when F=0, then g has to be 0. Thus, the value of g is zero at the centre of Earth.

Can high elevation make you sick?

If you travel to a high elevation without letting your body adjust to the new altitude, you may experience altitude sickness. Symptoms include headache and nausea. If you return to a lower elevation, your symptoms will likely go away without needing treatment. In severe cases, altitude sickness can be life-threatening.

Does water pressure increase with height?

Water pressure decreases with height.

Why the temperature decreases with altitude?

How does elevation affect temperature? … As you increase in elevation, there is less air above you thus the pressure decreases. As the pressure decreases, air molecules spread out further (i.e. air expands) and the temperature decreases.

What is value of capital G?

What is the value of capital G? In physics, the value of capital G (gravitational constant) was initially proposed by Newton. G = 6.67408 × 10–11 N m2 Kg–2.

What is value of G’on moon?

The acceleration due to gravity on the surface of the Moon is approximately 1.625 m/s2, about 16.6% that on Earth’s surface or 0.166 ɡ.

Does zero gravity exist?

The sensation of weightlessness, or zero gravity, happens when the effects of gravity are not felt. Technically speaking, gravity does exist everywhere in the universe because it is defined as the force that attracts two bodies to each other. But astronauts in space usually do not feel its effects.

Is value of g same everywhere?

Answer: Gravity is assumed to be same everywhere, on earth, but it varies because the planet is not perfectly spherical or uniformly dense. The value of G is 6.67 × 10^11 Nm^2/ kg^2. It is constant everywhere because is it is standard value termed as ( universal gravitational constant).

What is the minimum value of g?

The value of ‘g’ is minimum at the equator because Earth is not a perfect sphere. Its radius is maximum at the equator. Hence according to equation g = GM/R2 , the equator is the place where g will be minimum.

At what height the value of g is zero?

Near the surface of the Earth (sea level), gravity decreases with height such that linear extrapolation would give zero gravity at a height of one half of the Earth’s radius – (9.8 m. s−2 per 3,200 km.)

Why is g 0 at the center of Earth?

At the centre of Earth, the force due to upper half of the Earth will cancel the force due to lower half. In the similar manner, force due to any portion of the Earth at the centre will be cancelled due to the portion opposite to it. … Thus, the value of g is zero at the centre of Earth.

Where is gravity strongest on earth?

Earth’s Gravity is strongest on the ground, usually at sea level, and weaker as you move away from the core, eg the peak of Mt. Everest. The gravity at the poles is stronger than the equator, partly because the obloid earth is slightly wider, but only by a small ratio.

What does high elevation do to your body?

Altitude can also increase your metabolism while suppressing your appetite, meaning you’ll have to eat more than you feel like to maintain a neutral energy balance. When people are exposed to altitude for several days or weeks, their bodies begin to adjust (called “acclimation”) to the low-oxygen environment.

What should your oxygen level be at altitude?

Visitors coming to Summit from sea level might see their oxygen saturation drop to around 88% or lower before reaching levels typical at this elevation. Any oxygen saturation level below 100% is considered low, while measurements in the mid-80s could be a real health concern. Below 80%, organ function is disrupted.

What happens when you go from high to low altitude?

Altitude sickness occurs when you cannot get enough oxygen from the air at high altitudes. This causes symptoms such as a headache, loss of appetite, and trouble sleeping. It happens most often when people who are not used to high altitudes go quickly from lower altitudes to 8000 ft (2500 m) or higher.

Does changing pipe size affect pressure?

The pipe size and water pressure:

The variations in pipe diameter will not affect the static pressure. When the connection is open, the water pressure moderately decreases. The larger pipe offers minimum resistance to flow, and hence the water pressure decreases.

What height of water is 1 bar?

Water pressure is measured in bars, with 1 bar being the force needed to raise water to a height of 10 metres.

Will increasing pipe size increase flow?

Definition of Water Flow

The amount of water passing through a pipe at any given time is described as water flow. … Through any pipe size, higher water pressure will cause greater water flow. The pressure will decrease downstream, however, because of loss of friction and water velocity increase.

What is the relationship between temperature and altitude?

Temperature varies with altitude, as follows: In the troposphere, temperature decreases as altitude increases. In the stratosphere, temperature generally increases as altitude increases due to the increasing absorption of ultraviolet radiation by the ozone layer.

What happens to temperature as altitude increases?

How does elevation affect temperature? … As you increase in elevation, there is less air above you thus the pressure decreases. As the pressure decreases, air molecules spread out further (i.e. air expands) and the temperature decreases.

What is the hottest atmospheric layer?

The thermosphere is often considered the “hot layer” because it contains the warmest temperatures in the atmosphere. Temperature increases with height until the estimated top of the thermosphere at 500 km. Temperatures can reach as high as 2000 K or 1727 ºC in this layer (Wallace and Hobbs 24).
