A: The mass would not change: 30kg.
A: The Earth would be about 5.9742 × 1024 kg
The mass is physical quantity measured in kilograms, and the weight is a force measured in Newtons.The weight depends on the mass of the planet you are standing on, and altitude. At sea level on earth, 1 kg presses on a scale with 9.8 Newtons of force, 30kg with 294 Newtons, but the scale shows 1kg or 30kg respectively for weight because we tend to think of mass and weight as synonymous.A very precise spring scale is going to show lower weight at higher altitudes! In orbit, the weight is zero; even though the mass is the same! Because of this variation with altitude, scales that must measure mass accurately do not depend on springs.
No. The mass of the moon is a fraction of the earth's mass.
Yes. The mass of the sun is about 333,000 times that of Earth.
The mass of the moon is about 1/80 that of Earth.
The mass of planet Earth is 5.9736 × 1024 kg
On Earth, gravitation is approximately 9.8 meters/second square. Therefore, multiply by 9.8.
Work = Force x DistanceForce = Mass X Gravity (Near earth approximation)SoWork = 30kg x 9.8 m/s2 x 20m = 5880 joules
2kg
30kg = 30kg.
6,000 J
That's 3-4 times the mass of our Sun; I would say that such a mass getting that close to Earth would move Earth out of its orbit. Getting so close would also result in dangerous tidal forces.

3 tenths of 30kg = 3/10 * 30kg = 9kg
Your velocity is 1.73 meters per second.
300 kg
60 kg-m/s
20% of 30kg= 20% * 30= 0.2 * 30= 6kg
