What does the radius of a sphere?
The radius of a sphere is equal distance from the center of the sphere to all points within the sphere.
Segment joining the center to a point on a sphere?
It is the radius of the sphere
What do you call the distance from the center of the sphere to a point on the sphere?
The radius
Intersection of sphere and plane that contains center of a sphere?
great circle
A round figure who surface is at all points equidistant from the center?
A rounded figure that has all surface points equidistant from the center is a sphere. A common object that is a sphere is a tennis ball.
Can centre of mass of a body can exist at point where there is no mass of the object?
No, the center of mass of a body is a point where the entire mass of the body can be considered to be concentrated. If there is no mass at a point, the center of mass cannot exist at that point.
Is center of gravity lies where there is no mass?
That all depends on the shape of the object and how its mass is distributed. The center of gravity of a solid sphere is at the center of the solid sphere. The center of gravity of a solid cube is at the center of the solid cube. The Earth's center of gravity is at the center of the Earth, and there's certainly plenty of mass there. But the center of gravity of a ring is at the center of the ring ... an open space where the finger goes.
When the force of gravity is calculated using a large spherically symmetric mass like the Earth the distance is measured to the centre of the sphere why is this so?
Teh force of gravity is measured form the center of gravity, thus the center of gravity of the object is appropriately the center of the force. The center of the sphere is also the center of gravity of the sphere.
What is the center of gravity for a spherical object?
The center of gravity for a spherical object is located at the exact center of the sphere. This point is equidistant from all points on the surface of the sphere, making it the point where the force of gravity can be considered to act on the object.
What is the effect of gravity inside a solid sphere?
The effect of gravity inside a solid sphere is that it pulls objects towards the center of the sphere, with the force of gravity decreasing as you move towards the surface. This is because the mass of the sphere is concentrated at the center, creating a gravitational pull towards that point.
Center of mass of Earth's atmosphere?
The center of mass of Earth's atmosphere is approximately the same as the center of mass of the Earth itself. This is because the atmosphere is a relatively thin layer compared to the size of the Earth, and its mass is distributed around the planet in a way that does not significantly shift the center of mass.
How does the centre of gravity change as the size of the object changes?
The center of gravity of an object does not change with the size of the object because it depends on the distribution of mass within the object, not its overall size. If the distribution of mass within the object remains constant as the size changes, the center of gravity will also remain constant.
Is the mass the same as a diametre?
No. Mass is the weight of an object. Diameter is the distance from one side of a circle or sphere to the other side passing through the center.
What is the electric potential at the center of a sphere?
The electric potential at the center of a sphere is zero.
Is the center of a great circle also the center of a small circle?
No. Every circle on the sphere whose center is also the center of the sphere is a great circle. If the circle's center is not also the center of the sphere, then the circle is a small circle.
What is the formula for the mass of a sphere?
The mass of a sphere is 4/3*pi*r3*d where r is the radius of the sphere and d is the density of the material of the sphere.
What will be centre of gravity of sphere full of water and it is leaking?
The center of gravity of a sphere full of water that is leaking will gradually shift as the water leaks out. Initially, the center of gravity will be at the geometric center of the sphere. However, as water leaks out, the center of gravity will move towards the direction of the leak due to the changing distribution of mass within the sphere. The final position of the center of gravity will depend on the rate of leakage and the amount of water remaining in the sphere.
