Surface tension is in equilibrium.
The shape of a sphere has the highest volume to surface area to radius ratio. This shape is the lowest energy level a volume of liquid can have.
Deforming it into another shape would involve an increase in surface area and an increase in the average radius.
The surface tension of water is such that it will attempt to create the smallest surface area possible. That will always be a sphere.
No. In fact it is always finite - unless the sphere itself is infinite.
Water Sphere was created in 2005.
The water displacement of a sphere can be calculated using the formula for the volume of a sphere, which is V = (4/3)πr^3, where r is the radius of the sphere. The volume of water displaced by the sphere is equal to the volume of the sphere when it is submerged in water.
always a circle.
No
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.
yes the moon is always a sphere it just looks different as it rotates around the earth and how the sun shines on it
A sphere's height will always be the same as its diameter.
It will be a point if the plane is tangent to the sphere.
always a circle.
A sphere rolls because a sphere is like a ball and a ball would roll. Remember round stuff always roll
