What are Possible strategies for finding the mass of the earth?
One possible strategy for finding the mass of Earth is using Newton's law of universal gravitation, combined with measurements of the gravitational constant, radius of the Earth, and the acceleration due to gravity. Another approach is to analyze the motion of objects in Earth's orbit, such as satellites, to calculate the mass of the Earth. Additionally, geophysical methods, such as measuring the density distribution of Earth's interior, can provide insight into the mass of the Earth.
Who discovered the weight of the Earth?
The weight of the Earth was not discovered but calculated by Sir Isaac Newton using the law of universal gravitation. He estimated the Earth's mass and combined it with the gravitational constant to calculate its weight.
How do scientist calculate the weight of the earth?
First of all let us make a correction. It is not weight of the earth it is only MASS of the earth. By gravitational field concept we arrive at one expression for acceleration due to gravity as g = G M/ R2 G - universal gravitational constant. R-radius of the earth. g-of course measured by the simple pendulum experiment. Knowing g, G, R, we can compute M ie mass of the earth as M = gR2/G Cavendish was the first scientist who found the mass of the earth. But we say so colloquially that he was the first man who weighed the earth.
What is Calculate Average Density Of The Earth?
The average density of the Earth is approximately 5.52 grams per cubic centimeter. This value is determined by considering the total mass of the Earth and its volume. The density varies throughout the different layers of the Earth, with the core being the most dense.
How many grams of oxygen in the Earth's crust?
Oxygen makes up about 46.6% of the Earth's crust by weight. The approximate total mass of the Earth's crust is around 2.7 x 10^22 grams. Therefore, you can calculate the grams of oxygen in the Earth's crust by multiplying these two percentages.
How do you calculate mass of an object on Jupiter?
Find what the mass here on earth is then multiply it by three
How do we know the mass of the Earth?
The mass of the Earth is determined by measuring the gravitational pull it exerts on objects. Scientists use the laws of physics and observations of the Earth's orbit to calculate its mass.
What is the formula for calculating the mass of the Earth?
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
How do you calculate weight from mass?
Weight = Mass X (acceleration due to gravity), which on Earth is 9.8m/s^2.
What is the mass and weight of a 10-kg object on Earth?
10 kilograms is the mass. To calculate the weight (in newtons), multiply the mass by 9.8.
How do you calculate the weight of a dog that has a mass of 75 kilograms?
On Earth, 75 kilograms of mass weighs 165.35 pounds. That's quite a hound!
What is mass of package on the moon in kg if package weighs 108N on earth?
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.
Calculate the average mass and density of the earth?
(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
How do you calculate the weight in newtons of mass 40kg?
You multiply the mass by the gravity. Normal Earth gravity is about 9.8 (in meters/second2, or the equivalent newton/kilogram).
How can you calculate the density and volume of earth give the formula?
Density = mass / volume since earth is nearly spherical, Volume = (4/3)pi x r3 find volume, then divide this into the mass.
Using the known distance earth is from the sun calculate What is the speed that earth is moving through space in relation to the sun?
To calculate this speed, you need some more numbers, not just the distance from Earth to Sun. You need to know:* The gravitational constant * The distance from Earth to Sun * The mass of the Sun You DON'T need the mass of the Earth. Assume any mass; you can just call the mass of the Earth "m". Then calculate an expression for the gravitational attraction between Earth and Sun. Divide by the mass of the Earth, and you get a centripetal acceleration. Assuming a circular orbit for simplicity, the centripetal acceleration must be just this force. Use the formula for the centripetal acceleration along a circle (a = v squared / radius). (Don't forget to convert the distance from Earth to Sun, to meters!) Solve for "v".
What is a way to calculate the mass of an object when you multiply its density by what?
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.
