What else can I help you with?
How does weight of a body vary inside the earth?
People are (so far) not able to get very deep inside the Earth, so there is not that much variation, however, the closer you get to the center of the Earth, the less you would weigh. At the exact center you would be weightless.
What would happen if you drilled a hole in the Earth?
After about 20 miles, you would reach the mantle.
Hottest part of earth?
on the surface i would say the area hovering near the equater. the inner core the center of the earth is the definite hottest why I don't know. I guess because when volcanoes erupt the lava is boiling hot. but nobody I ever heard of drilled to the center of the earth to prove that point.
What would happen if you drilled a hole through the earth?
If you were to drill a hole through the Earth, you would create a tunnel that goes from one side of the planet to the other. Gravity would pull you towards the center of the Earth, and you would experience weightlessness at the midpoint. The journey would be extremely hot and the pressure would increase as you got closer to the center. It is not physically possible to drill a hole through the Earth due to the extreme conditions and technological limitations.
What is the value of Earth's gravitational field at the center of the Earth?
In the cavity at the center of the Earth, your weight would be zero, because you would be pulled equally by gravity in all directions. - The gravitational field of Earth at its center is zero.
Why can't we go to the centre of the earth?
We cannot go to the center of the Earth because of the intense heat and pressure at that depth, which would be extremely dangerous for human survival. Additionally, the technology needed to drill to such depths is not currently available or practical.
Why value of 'g' decreases when you go inside the earth?
Because the value of "g" varies directly with the sum of the masses of the two bodies acted upon by the force of gravity. If you go inside the earth, only part of the mass of the earth will be attracting you toward its center; the mass of the part of the earth that is farther from the center than you are will be attracting you away from the center. If it were possible to reach the center of the earth, the value of "g" would reach zero because the mass of the earth would be acting upon equally you in all directions.
Do objects become lighter as they get closer to the center of the earth?
Objects masses would not change, but the pull of gravity on an object from another object when the first is inside the other is effectively zero when the inside is at the center of mass of the outer. If the Earth were a thick walled but hollow sphere, objects would stick (weakly) to the inside surface as well as the outer.
What is the weight of the body at the center of the earth?
In theory, at the center of the Earth you would have no weight.
How fast does it take to get to the center of the earth?
It would take one hour to get to the center of the earth
If you drilled a hole straight through the earth and dropped a bowling ball down the hole would the ball come to rest at the center?
The ball will NOT come to rest. It will oscillate around the center of the earth in simple harmonic motion. Incorrect. the ball will rapidly reach a terminal velocity ( maximum speed given the resistance of the air). as the ball gets closer to the center of the earth it will slow down as the force pulling the ball towards the earth it has already passed through becomes closer to the force of the earth the ball has not yet passed. Upon reaching the center of the earth. the bal will minimal , and for a short time, oscillate until rapidly coming to rest at the center of gravity.
Is the center of mass between Earth and the sun exactly half way between the two?
No, the center of mass between Earth and the sun is not exactly halfway between the two because the sun is much more massive than Earth. The center of mass is closer to the center of the sun, but it is not exactly at the halfway point.
