Let g_e the acceleration of gravity at the surface of the Earth, M_e the mass of the Earth, and R_e the radius of the Earth

For Mars, we have g_m, M_m, and R_m.

g_e=G*M_e/(R_e)^2

g_m=G*M_m/(R_m)2

g_m/g_e=(M_m/M_e)*(R_e/R_m)^2=(0.11)(1/0.53)^2=0.11/(0.53)^2

g_m=0.11*g_e/(0.53)^2

You can view this question as what is the surface area of the 13 inch round pan, and then with it being 2 inches deep, calculate the volume.

Surface area = pi * r ^ 2, where r is the radius of the pan

In this case, the diameter is 13 inches, so the radius will be 6.5 inches.

Putting it into the formula, we get surface area = pi * 6.5 ^ 2.

Because of BEDMAS, we have to do the square before we multiply.

Surface area = pi * (6.5 ^ 2)

= 132.7square inches.

To get the volume, we multiply this surface area by the depth of 2 inches.

Volume = surface area * height

Volume = 132.7 * 2

Volume = 265.4 cubic inches.

Good luck,

Paul

Yeah its possible to take a look at mars as you can see earth through Google Earth.You can also see the mountains and plain on Mars.

To do so follow click on following link:

Have fun navigating through Mars without a space ship! ;)

Gravity is a mutual attractive force between any 2 bodies (masses). It is classified as a weak force (by comparison with molecular forces) but is thought to be unlimited in range.

It increase with the masses of the attracted bodies, but decreases with the square of distance, so that if you go twice as far from Earth, the effect of gravity on you is lessened by a factor of 4.

So this means that a huge fully loaded oil tanker is attracted to the wharf, which is attached to the Earth. Such forces usually can be ignored, but not when launching rockets for instance.

It is thought that a theoretical particle called the Graviton influences gravity by interacting with something in Einstein's Theories called a stress-energy tensor. The trouble is that the Graviton has not been detected, so other theories about what makes gravity are possible.

The same reason for the very small force of gravity between two PCs...why do you ask?

Gravity is a force that causes a mass/object to be attracted to another mass/object similar to magnetism. Gravity is not an object itself located in any particular place like earth or space.

The satellites stay in orbit around the earth because the force propelling the satellites forward away from the earth is balanced by the gravity pulling them back to earth.

The satellites move too slow and they fall back to earth. If they move too fast, they fly out further into space and out of orbit.

I hope this answers your question.

A cubic foot is a unit of volume. A pound can be a unit od mass (weight) or a currency. Either way a volume cannot be converted into a mass nor a currency.

If you are doing homework read carefully the question to figure out what substance they are talking about.

Once you know the substance look up its density or specific gravity and do the calculation

mass (in pouunds) =density (in pounds per cubic foot) * volume (in cubic feet)

As you see, if you know the density (specific gravity) in pounds per cubic foot, you can calculate the mass of any volume of that substance (in cubic feet).

And please, never try to convert a volume into a mass.

Because Gravity pulls equally in all directions. When the Earth was forming, it was entirely molten rock. And, since Gravity pulls equally in all directions, the Gravity of the Earth pulled the molten rock into a sphere.

It is not possible for any metal (or anything for that matter!) to act opposite to gravity.

Everything has a weight (effect of gravitational pull on a mass), and is pulled towards another mass (in this case Earth) but many things are ligher than air, so they will float away from the earth until the air becomes so thin that its boyant effect is no longer stronger than the gravitational effect, and the objet can rise no further.

If a free body could be positioned at decreasing distances from the center of the earth, the mass of the earth would become more distributed around the free body, until at the very center of the earth the net gravity on the body would be zero. At this point the mass of the earth (and the force of gravity) would be uniformly distributed in all directions.

You sort out the formula for the surface you have to calculate then substitute the numerical values for the variables (sides, bases, heights), the constants if any (pi, etc.) an press = to get the result

Ex Square with side= 2m

Surface area=side^2

Area : 2 [X^2][=] result is 4 m^2

Circle of radius r=3 cm

Area: Pi* 3[^2]=28.27 cm^2
