# How many moons would it take to equal the mass of earth?

# Why would an equal arm balance read the same mass on earth as well as the moon?

Since the balance depends on gravity being equal on both sides of the arm, the actual value of gravity is not important. Hence the reading of the balance is the same on ea…rth as well as on moon.

# How many earths would it take to equal the diameter of Jupiter?

Jupiter's diameter = 11.21 x Earths (142,984km). That does not sound much, but we are just talking about one dimension here. If the volumes are compared, the size difference i…n the one dimension is cubed, giving Jupiters volume around 1400 times the volume of earth (actually nearer to 1320 time Earths volume due to Jupiter being a `squashed sphere`).

# How many earths would it take to equal the mass of the sun?

It would take about 333,000 earths to match the mass of the sun.

# If a person has a mass of 71kg on earth what would be their mass on the moon be?

11.83 that is the 1/6 of his mass in earth

# An object has mass of 120g on earth on the moon it would a mass of?

If the object's mass is 120g, then it's 120g. On Earth, on the moon, on Mars, or floating weightless in a space ship coasting from one of them to another. Weight depends on …where you are, but mass doesn't.

# How many days it would take earth to moon?

How many days to walk to the moon? This is a difficult one. Anything from 1-0000-00 days to 2-000-000 days that's if anyone could walk to the moon- you probably can a…s the gravity is so low in space

# How many earth's would it take to equal 1 sun using mass?

The Sun is by far the largest object in our solar system. It contains 98% of the solar system's total mass. The Earth's mass is 5.9736×1024 kg. The Suns mass is 1.9891 ×1030… kg. So the Sun is 332946 times the mass of the Earth. The Sun's diameter is about 100 times that of the Earth. So, you'd have to line up 109 Earth's end-to-end to stretch across the face of the Sun and it would take about 1,000,000 Earths to fill the volume of the Sun.

# Would your mass be the same on the moon as on the earth?

Your weight would change because of the Moon's lower gravity, but your mass would remain the same because no matter is added or taken away from you Mass is the same, it is w…eight that is different due to the force of gravity. The mass of a body is a measure of how much matter it contains. Yes, mass is the same everywhere. Weight on the other hand depends on the gravity where the object is located. An object that weighs 100 pounds on Earth would weigh 16.6 pounds on the Moon Yes, mass is the same. Mass is a measurement of how much matter an object contains. Mass is not affected by gravity. Mass will stay the same. the weight will change due to gravity. ! Your mass on the moon would be the same as your mass on earth. Mass is the actual amount of matter present. Your weight would change since the moon has a different gravitational acceleration than earth. We = ( m ) ( ge ) Wm = ( m ) ( gm ) _________________________________________________________________________________________________ The mass is the samethe Moon has about 1/6th the gravity on earth. Accordingly, the weight on the moon is 1/6th the weight on earth.

# How many moons would equal the diameter of the earth?

The Moon is one-fourth the diameter of the Earth, so that means that four Moons would fit into the diameter of the Earth. This does not mean that the Moon is one-fourth the si…ze of the Earth; the Earth is significantly larger.

# How many ping-pong balls would it take to equal the mass of Earth?

Approximately. 22,127,000,000,000,000,000,000,000,000, over 22 octillion!

# How many days on the moon will it take to equal a year on Earth?

Previous answers was: 365 days, it goes around the sun at the same time as the earth. Although this is true, let me add something... If you are counting days as sunrise …to sunset on the Moon, then you need to consider the fact that the Moon has only 13 days in a year. So if you were to live on the Moon you would count 13 lunar days to go around the Sun. I'll explain why.... The Moon revolves around the Earth once every 28 days. It also rotates once in 28 days. This is why the same side always faces the Earth. We call the other side the dark side of the Moon because we never see it. Okay, so if the Moon takes 28 Earth days for one Moon day, then divide 365.25 (adjusting for Leap Year) by 28. That comes to 13.04 days for a Lunar Year. ==== A fly on the wall added: I get 13.369, using the more accurate period of the moon's revolution: 27.32 Earth days.

# How many moons will it take to equal the mass of the earth in grams?

The first thing to say is, it doesn't matter if it's in grams or tons or whatever, the ratio (one divided by the other) will be the same. The second is that this is easy to …do yourself, so you may as well. Go to the Wikipedia article on the moon. It lists the moon's mass. In fact, it even gives the moon's mass in terms of Earth's mass (which saves you the trouble of having to look up the Earth's mass). You want the reciprocal of the moon's mass in Earths - where it says for mass "7.3477 × 1022 kg (XXX Earths)" you want 1 divided by the XXX. The answer should be good to about two significant figures, so if the answer is "73.85341" (it isn't) then just say "74".
