If a neutron star has a radius of 10 km and rotates 642 times a second what is the speed of the surface at the neutron star's equator in terms of the speed of light?
The Radius of the Star is 10 KM. Now we need to find the diameter. Circumference equals pi times the Diameter. That is twice the Radius, which is 20. Now we need to get the Diameter. We multiply the diameter by pi. 20 times 3.1416. 20 * 3.1416 = 62.838. Now we multiply the circumference in kilometers by the speed. 62.832 * 642 = 40,338. Now we take the speed of light, 299,997 per second and divide it into the speed of a point on the equator of our star going 40,338 kilometers per second. 40338 / 299997 = 0.1345

Which has a linear size or radius closest to the radius of a neutron star?
Br is the atom with the smallest. K+ is the ion with the smallest radius. In general, the shape with the smallest radius has the smallest diameter

What is a terrestrial radii?
Terrestrial radii refer to the measurements of the Earth's radius, which is approximately 6,371 kilometers (3,959 miles) when averaged. This value can vary slightly based on whether it's measured from the equator, where the Earth bulges due to its rotation, or from the poles, where it is slightly flattened. The equatorial radius is about 6,378 kilometers (3,963 miles), while the polar radius is about 6,357 kilometers (3,950 miles). These variations are important for understanding Earth's shape and its gravitational field.
What is the relationship between raidus and area?
The relationship between the radius and area of a circle is as follows: Area of circle = 3.14 x Radius x Radius or 22/7 x Radius x Radius
What is the radius at the equator?
The Equatorial radius is 6378.1Km
What is the distance from the surface to the center of the earth?
That's the Earth's radius. It's about 6378 kilometers at the equator. That's 3963 miles.
What is a Segment of the equator?
A segment of the equator is a portion of the Earth's surface that lies along the imaginary line that divides the Earth into the Northern and Southern Hemispheres. This segment is a circle with a radius equal to the Earth's radius and measures 1/360th of the Earth's circumference.
What is the distance from earths surface to the center of earth?
That's the Earth's radius. It's about 6378 kilometers at the equator. That's 3963 miles.
What is the distance from the earth's surface to earth's center?
That's the Earth's radius. It's about 6378 kilometers at the equator. That's 3963 miles.
What is equatriol raduis?
If you assume thatequatriol = equatorial raduis = radius then the equatorial radius is the radius of the spheroid measured at its equator. It would be = length of the equator/(2*pi)
Which star has a radius of 10 km?
That's the approximate radius of a neutron star, a.k.a. a pulsar.
What is the distance from the of Earth surface of the to the center?
This is the Earths radius. The Earth has a radius of 6371km on average. It is a slightly 'squashed sphere' though, due to its spin pushing out at the equator. Its polar radius is 6357km, while its radius at the equator is 6378km
What is Equatorial Radius?
Half the distance in a straight line from one side of a planet to the other through the centre of the planet with the distance measured from the equaor on both sides. In other words, the radius of the sphere of the planet measured, not at the pole, but at the equator. It is important to distinguish between polar radius and equatorial radius because no planet is an exact sphere, but 'bulges out' at the equator because of 'centrifugal force' as the planet rotates. This is most marked in the gas giants of the solar system especially Jupiter and Saturn, which look distinctly flattened at the poles when viewed through a telescope, so that the polar radii are very much smaller that the equatorial radii.
When body rotates the angle through which an arbitrary radius turns is called angular?
When the body rotates, the angle through which an arbitrary radius turns is called angular displacement. It is measured in radians and represents the change in direction of the radius vector as the body rotates.
Why the motion of simple pendulum is slow at equator?
A pendulum will swing slowest when closest to the equator. Why is this? The time period, T, of the swing of a pendulum is given by: T=2π√(l/g) where l is the length of the pendulum and g is acceleration due to gravity. Because the Earth is spinning, there is a bulge at the equator and the poles are slightly flattened. Hence on the equator the radius to the centre of the earth is greater than the radius at the poles. The equatorial radius is 6378.1km while the polar radius is 6356.8 km The value of g at the Earth's surface relates to the values of the Earth's radius, r, at that point using an inverse square law ie g is proportional to 1/r2 At the North Pole, g is about 9.83m/s2, while at the equator, g is smaller, at only 9.79m/s2 . So the period of a pendulum will be longer (i.e. slowest) at the equator than at the pole
What is Enceladus's radius at the equator?
It is roughly 252 km.
