if g=9.8m/s, G=6.7*10-11Nm2kg-2,calculate the mass of earth, if the radius of the earth is approximately 64m
On Earth, 75 kilograms of mass weighs 165.35 pounds. That's quite a hound!
(all figures approximate)Mass of earth = 5.97 * 1024 kilogramsRadius of earth = 6.371 * 106 metresVolume of earth = 4/3 * pi * radius3 = 1.0832 * 1021 cu metresSo:(average) density = mass / volume = 5,510 kgs / cu metre
You multiply the mass by the gravity. Normal Earth gravity is about 9.8 (in meters/second2, or the equivalent newton/kilogram).
Density = mass / volume since earth is nearly spherical, Volume = (4/3)pi x r3 find volume, then divide this into the mass.
The mass of Earth can be calculated using the formula: mass = (density) x (volume). The average mass of Earth is about 5.97 x 10^24 kilograms.
Find what the mass here on earth is then multiply it by three
if g=9.8m/s, G=6.7*10-11Nm2kg-2,calculate the mass of earth, if the radius of the earth is approximately 64m
Weight = Mass X (acceleration due to gravity), which on Earth is 9.8m/s^2.
10 kilograms is the mass. To calculate the weight (in newtons), multiply the mass by 9.8.
On Earth, 75 kilograms of mass weighs 165.35 pounds. That's quite a hound!
To find the mass of the package on the moon, you can use the equation: weight = mass * acceleration due to gravity. The acceleration due to gravity on the moon is about 1/6th that of Earth's. So, if the package weighs 108N on Earth, its mass on the moon would be about 18 kg.

You can calculate the mass of an object by multiplying its density by its volume. The formula to calculate mass is: mass = density x volume.
In order to calculate that quantity, you would need a number to use for the Earth's mass.
