## What is radius of moon Class 9?

“The mass of the moon is 7.35×1022kg. The radius of the moon is 1.74×106 m.”

## How is the radius of the Moon calculated?

**“”The radius of the moon is 1738 km, whereas the radius of Earth is 6371 km; thus the moon is relatively large in relation to its parent planet.” Moore, Patrick….Diameter of the Moon.”**

## What is the radius of the moons orbit?

“The Moon’s orbit (its circular path around the Earth) is indeed getting larger, at a rate of about 3.8 centimeters per year. (The Moon’s orbit has a radius of 384,000 km.)”

## What is moon radius in km?

“Size and Distance With a radius of about 1,080 miles (1,740 kilometers), the Moon is less than a third of the width of Earth. If Earth were the size of a nickel, the Moon would be about as big as a coffee bean. The Moon is an average of 238,855 miles (384,400 kilometers) away.”

## What is the radius of Earth Class 9 physics?

“The radius of the earth is about 6370 km.”

## What is a radius Class 9?

“The radius of a circle is the length of the line from the centre to any point on its edge. It can also be defined as, the distance from the centre of the circle to any point on the circle is called the radius.”

## What is the formula for moon?

“The Moon has a smaller mass than the Earth and so the pull of gravity by the moon on an object is smaller than on the earth. The moon has a smaller gravitational field strength. On the Moon, g = 1.6 N/kg. In other words, a 1 kg mass has a weight on the Moon of 1.6 N.”

## What is round circle of moon?

“The ring, or a lunar halo, is caused by the refraction and reflection of light from ice crystals that are suspended in thin, wispy, cirrus or cirrostratus clouds that are at high altitudes. As light passes through the ice crystals, it is bent at a 22-degree angle, creating a halo of 22 degrees.”

## How many radians is the Moon?

“For instance, the Moon is located r = 384,000 km from Earth and it has a radius of d = 1,738 km, so its angular radius is 1,738/384,000 = 0.0045 radians.”

## What is the main radius of the Moon?

“The moon’s mean radius is 1,079.6 miles (1,737.5 kilometers) and the mean diameter is 2,159.2 miles (3,475 km). Compared to Earth, the moon is less than a third the width of our home planet, according to NASA (opens in new tab).”

## What is the radius of an orbit?

“The orbital radius, 𝑟 , is the distance from the center of mass of the larger object to the orbital path. If we know the value of 𝑟 , we can also work out the total length of the orbital path, or the circumference of the orbit.”

## What is the radius of the smallest moon?

“With a mean radius of 6.2 miles (10 kilometers), assuming an albedo of 0.04, Leda is the smallest moon in the Himalia group, a family of Jovian satellites which have similar orbits and appearance, and are therefore thought to have a common origin.”

## What is the diameter of moon?

““

## What is a mass of moon?

“The mass of the Moon is 7.347 x 1022 kg. That sounds like a large number, and I suppose it is compared to the mass of a single person, a car or even a building. But you’ve got to keep it in context. The mass of the Moon is only 1.2% the mass of the Earth.”

## What is radius of curvature Class 11?

“In other words, the distance between the pole and centre of curvature of the spherical mirror is called its radius of curvature.”

## What is the radius of sun?

““

## What is radius of a circle Class 7?

“A straight line from the centre to the circumference of a circle or sphere is called as Radius of circle.”

## How do you find the radius of a class 9 circle?

“Radius = Diameter/2 Diameter is the longest chord of the circle.”

## What is the weight of moon Class 9?

“The mass of the moon is 1100 times and its radius 14 times that of the earth. As a result, the gravitational attraction on the moon is about one sixth when compared to that on the earth. Hence, the weight of an object on the moon is 16 th of the weight on the earth. Q.”

## What is the radius answer?

“Radius = r = √A/π”

## What is the mass and radius of Earth Class 9?

“[Mass of the earth is 6 x 1024 kg and radius of the earth is 6.4 x 106 m].”
