# 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 eggs would it take to reach from the earth to the moon?

Good question! A typical chicken egg is about 5 cm in length, thought they may vary in size widely. The distance to the moon is 384,403 kilometres, or about 7,…688,060,000 eggs.

# 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.

# How many electrons would it take to equal the mass of a proton?

1800 electrions

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

Yes, your mass remains the same no matter where you are. It id your weight that changes based on the pull of gravity.

# 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 electrons would it take to the equal the mass of a proton?

# How many peas would it take to reach the moon from earth?

First, you need to find the information you need to solve for the answer. A pea measures approximately 1 cm in diameter (from one point to the point on the opposite end). The …distance from the center of the Earth to the center of the moon is about 384,467 km. If you subtract from this distance the average radius of the Earth (6,378 km) and the average radius of the moon (1,738 km), you find 376,351 km. Convert the diameter of a pea, 1 cm, to kilometers: .00001 km. Now, divide the distance from the surface of the Earth to the surface of the moon by the diameter of a pea. The answer is: 37,635,100,000 peas. That's about 5 times the population of the Earth, and about a third of the estimated number of stars in this galaxy!

# 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 mars would it take to equal the mass of earth?

Mars is 0.107 times the mass of earth. The reciprocal of that is the number of planets the mass of Mars it would take to equal a planet the mass of earth, or a little over 9 …and 1/3.

# 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".

# Why would your mass be the same on Earth and the Moon?

mass is not variable and does not change. It is weight that changes - weight = mass x gravity acceleration so weight is less on the moon.
