What is the mass of the object . When the weight of the object is 1200 N ?
The weight of an object at the surface of a planet is proportional to planet's mass and inversely proportional to the square of the radius of the planet. Jupiter's radius is 11 times Earth's and its mass is 320 times Earth's. An apple weighs 2.20 N on Earth. How much would it weigh on Jupiter?
A planet has 1/9 the earth's mass and half its radius. It orbits a star with six times the sun's mass with an orbital period of 48 years.
Suppose aliens from this planet crash their spaceship in New Mexico. If the spaceship weighs 1200 Zorgs on their planet, then what is the weight in New Mexico, in Zorgs?
I got 533.3 Zorgs but it was incorrect.
