List the steps SI units that would be used to measure the following quantities:the weight of the planet jupite

Answer 1

You don't get the weight, but the mass... how to do it? "Once you know how far away a planet is, you can use the orbital periods (P) of moons circling a planet and how far the moons are from the planet (d) to measure the planet's mass" ...
Planet mass = (4p2/G) × [distance3/(moon's orbital period)2] - moon's mass. The moon's mass can usually be ignored.

Planet diameter = 2p × (distance to the planet) × (planet's angular size in degrees)/360°.
Planet volume = (p/6) × (planet diameter)3.
Density = mass/volume.

Answer 2

Tell your teacher the planet Jupiter doesn't have a weight, it has a MASS. Weight is a force. The SI unit for force is Newtons.

However, describing the weight of Jupiter is meaningless. Its mass, however would use the SI unit of kg, kilograms.
