# Neptune has a mass 17.2 times larger than that of Earth and a radius 3.88 times larger A person weighing 154 lb on the Earth would weigh how much on Neptune?

The calculation for weight is universal gravity times the mass ofthe person times the mass of the planet divided by the radius ofthe planet squared. This means that 154 lbs. o

# Assume a person weighs 980 N on the surface of earth. What is the weight of the person whose is three times the distance from the centre of Earth?

\nThe person three times the distance will weigh 1/3^2 the weight or 1/9 the weight.\n. \n980=mGM/R^2 the first person on the earth's surface. The second person, p2 weighs\

# Neptune has a mass 17.2 times larger than that of Earth and a radius 3.88 times larger A person weighing 137 lb on the Earth would weigh how much on Neptune?

The formula for calculating this is F equals Gmm divided by rsquared. You should get F is equal to 739. The conversion is 4.44Nis equal to one pound.

# What is the travelling time from planet earth to planet Eris?

Thr Traveling Time To Eris From Earth Takes About 3 Years 7 Months.

# If you travel into space is the time taken to get to say another planet the same as the time on earth?

For all practical purposes the answer is yes. Einstein's time dilation does not happen in any meaningful way at the speeds today's manned spacecraft archive.

# What is the length of traveling time from earth to earth?

You need to be a bit more specific, from where to where?

# The amount of time it takes to travel to the planet of Jupiter from the earth?

what is the speed in amount of time and plant is Jupiter in it must include light, 500 km/hr,etc.)

# What planet is 4 times the size of earth?

The radius of Uranus is roughly 4 times the radius of Earth.\n. \nHowever, in volume, it would be around 4 3 = 64 times larger than Earth. \n. \nHence, There is no planet

# If on Earth Sara weighs 100 lbs and she moves to a planet that is 5 times larger in radius but has the same mass as Earth how much would she weigh?

Sara would weigh exactly the same as on Earth. The radius of the planet does not make any difference on ones weight. The mass of the planet is the crucial factor.

# If on Earth Sara weighs 100 lbs and she moves to a planet that is 5 times larger in radius how much would she weigh?

This is not really a question that can be answered given the wording as it stands. A planet's radius has little or nothing to do with its MASS, which is what 'causes' gravity.

C. =

# If a planet existed whose mass was twice that of earth and whose radius is 3 times that of earth.how much will a body of 1kg mass weight on this planet?

The mass is twice as much, so multiply by 2. The radius is 3 times as much--the gravitational force is inversely proportional to the square of the radius, so multiply by 1/9.

# A person weighing 800 newtons on earth travels to another planet with twice the mass and twice the radius of earth the person's weight on this other planet is most nearly?

The force of gravity is proportional to the mass, and inversely proportional to the SQUARE of the distance between them. If we double the mass at the same distance, we double

# What is the Travel time from earth to another galaxy?

That naturally depends on how fast you plan to travel. We don't have to talk about too many different modes of travel, to show that it's a trip that's not even worth thin

# If you weigh 155 on earth and have a mass of 63 if you travel to the moon will your weight or mass change and why?

"Mass" is the amount of 'stuff' of which you're made. It's you, like the color of your eyes. It isn't affected by things around you, it doesn't depend on where you are, and

# If an object weighs 80 kilogram on earth what will the mass weigh on another planet?

Mass measured in kilograms is always the same. True weight however is a force measured in Newtons not kg and this is the effect gravity has on a mass.

# How long does it take for the moon to travel around the earth 4 times?

To travel or orbit around the earth 4 times the moon will take 4 lunar cycles each lasting approx one month ususally a bit less e.g. 28 days.
