At the center, for every particle of mass in the earth toward which you're gravitationally
attracted, there's an equal particle with the same mass, located at the same distance
from you in exactly the opposite direction, balancing out the force toward the first one.
That statement assumes that the earth is a perfect sphere with the same distribution
of mass in every direction from the center. The real earth is oddly shaped, lumpy and
bumpy, so the acceleration of gravity wouldn't be exactly zero at the center.
At the center, for every particle of mass in the earth to attract you gravitationally, there's an equal particle with the same mass, located at the same distance from you in exactly the opposite direction, balancing out the force toward the first one. All of this is a theoretically ideal case. It assumes that the earth is a perfect sphere, with the same distribution of mass in every direction from the center. The real earth is lumpy, oddly shaped, and bumpy, so the acceleration of gravity wouldn't be exactly zero at the center.
In a zero-gravity environment, you would not experience the normal effects of G-force caused by ambient gravity. In a zero-g environment, you are essentially in free-fall, so you are weightless and there is no force acting on you to create a sensation of gravity.
No.
The Earth's gravitational pull is never zero, but it decreases with distance from the Earth's surface. At the point where gravity is negligible, it is often considered to be zero, but this can vary depending on the specific context.
Any time a person falls, they experience reduced gravity for a short time. If they fall a greater distance, the more likely they will experience something close to zero G. Sky diving, riding a roller coaster/ amusement park ride with a free fall component can get close to zero g. If you've been in a plane that hit turbulence and dropped quite a ways, you may have experienced zero gravity. Point is, zero is experienced during free fall, which is exactly what the astronauts are doing when they are in orbit.
Zero.
The value of acceleration due to gravity 'g' at the center of the Earth is theoretically zero because the mass of the Earth surrounds an object equally in all directions, resulting in a net gravitational force of zero at the center.
There will be no gravity. Objects will start floating.
No, at the center of the Earth, it would be zero. That's because the gravitation of different parts of the Earth, in different directions, would cancel.
If the Earth were to stop rotating, the value of 'g' (acceleration due to gravity) would remain approximately the same at the Earth's surface. The rotation of the Earth does not significantly affect the gravitational pull experienced on the surface.

well he is somewhere in the manga of the zero g. Look on fanpop for the picture
The most meaningful answer is zero G. You, the space-station and everything in it are in free-fall towards Earth. All are 'weightless' (but not massless).
Zero-g surgery probably isn't economically feasible at present. Sustained zero-g means in orbit. That costs a ton. Simulated zero-g like is effected in a plane that descends at a rate equal to the gravimetric constant (g), but it doesn't last long. Plus, is zero-g surgery safe? That is an open question.
Yes, at equilibrium, the standard Gibbs free energy change (G) is equal to zero.
The time period of a simple pendulum at the center of the Earth would theoretically be zero because there is no gravitational force acting on it. A simple pendulum's period is determined by the acceleration due to gravity, which would be zero at the center of the Earth.
The value of acceleration due to gravity (g) at the center of Earth is theoretically zero. This is because the mass surrounding the center exerts equal gravitational force in all directions, effectively canceling each other out at the center point.
