An astrounaut lands on a planet that has the same mass as earth and twice the diameterhow does the astrounaut's weight differ from that on earth?
The force between two objects due to gravity is proportional to the product of the two masses. That part doesn't change compared to his weight on earth.The force is also inversely proportional to the square of the distance between their centers. On the planet with a diameter equal to twice the earth's diameter, the distance is changed by a factor of 2, so the force is changed by a factor of (1/22) = 1/4. His weight on the alien planet is 25% of his weight on earth. Naturally we're assuming that the planet's mass is symmetrically distributed. It doesn't have to be homogeneous with constant density throughout, but it has to be evenly spread around the center. The geometric center of the sphere also has to be its center of mass, with no big off-center lumps.
Which planet has twice the earth period of revolution?
Mars has roughly twice the Earth's period of revolution.
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 the force; if we double the distance, the force is cut to one-FOURTH. So twice the mass and twice the distance; the force will be (800*2)/2^2, or 400.
If Earths mass decreased to one half its original mass with no change in radius then what is your weight?
That would depend on what happened to the Earth's radius as well, since gravity depends on the mass of the object and the square of the distance between them. So if the mass were doubled and the radius of the Earth also doubled, the force of gravity would actually go down by half!
Why does your weight decrease the farther away you get from the center of the Earth?
No. Mass is constant. Weight decreases.My answerNo Mass is a measure of how hard a thing is to move (it is measure in pounds or Kilos on the surface of the Earth as @ one Gravity they are equal)Weight reduces as you move away from the Earth as it depends on Gravity
How would your present weight change if earth twice the mass that it doe now?
It would double.
if the earth had twice it’s present radius and twice it’s present mass, what would happen to your weight explain your answer?
i will be twice as heavy
How would you present weight change if earth had twice the mass it does now?
If Earth had twice its current mass, the gravitational force would increase, and objects would weigh twice as much as they do now. This means that a person weighing 150 pounds on Earth would weigh 300 pounds on the hypothetical Earth with double the mass. The weight change would be a direct result of the increase in gravitational pull due to the added mass.
What way dose mass cores pond with weight?
The formula that relates them is: weight = mass x gravity If gravity doesn't change - which is the usual case close to Earth's gravity - you can say that weight is proportional to mass. That means that twice the mass results in twice the weight.
Dan has a mass of 55 kg on Earth. What is his mass on a planet that has twice Earth's gravity?
Dan's mass is the same as it is on Earth. His weight, however, is doubled.
Why is your weight not one quarter as much when you climb to the top of a tall tree twice as tall as you?
Your weight is not one-quarter as much when you climb to the top of a tree twice as tall as you are because your weight does not change when you move around within earth's gravitational field. You would have to move to outer space or to another planet to have your weight change.
What would be the effect on the mass and the weight of an object if the object taken to a planet with twice the gravity on earth?
the mass would stay the same no matter where you are and the weight is the force of gravity on an object, so depending on the gravity your weight would change
What would be the effect on the mass of the weight of an object if the object were taken to a planet with twice the gravity of earth?
the mass would stay the same no matter where you are and the weight is the force of gravity on an object, so depending on the gravity your weight would change
What is the simple present tense of change?
change or changes They change their clothes everyday. He changes his clothes twice a week.
What is the present tense of changed?
change or changes They change their clothes everyday. He changes his clothes twice a week.
What would be the effect on the mass and the weight of an object if the object were taken to a planet with twice the gravity of earth?
The mass of the object would remain the same because mass is an intrinsic property of the object. However, the weight of the object would double on a planet with twice the gravity of Earth since weight is the force exerted on the object due to gravity, which is directly proportional to the acceleration due to gravity.
Which planet more than dubiles your weight?
Everything on Jupiter weighs more than twice as much as on Earth. This means that Jupiter has a gravitational pull that is more than twice that of the gravitational pull on Earth.
