Density of a sphere?
you need the mass and radius of the sphere- density = mass divided by volume, so mass/volume. the volume of a sphere is 4 divided by 3 multiplied by pi multiplied by the radius squared. 4/3(π)(r^2).
How does the centre of gravity change as the size of the object changes?
The location of an object's center of gravity depends on the object's shape, and on how its mass is distributed throughout its shape, but not on its size. The center of gravity of a homogeneous sphere is at the center of the sphere, no matter whether the sphere's radius is 1 millimeter or 1 light year.
Suppose two worlds each having mass M and radius R coalesce into a single world Due to gravitational contraction the combined world has a radius of only ¾R What is the average density of the com?
Density is calculated as mass divided by volume.To get the total mass, add the masses of the individual worlds.To get the volume, use the formula for a sphere. Presumably it would coalesce into a sphere.Finally, divide the mass by the volume.
What is the magdeburg hemisphere formula?
Pressure = Force / AreaAssuming you have created a force by hanging a certain mass from one hemisphere thenForce = Mass * GravityWe need to consider the area on which the air pressure is acting upwards and supporting the mass. We could look at all of the vectors acting inwards on the lower half of the sphere, but this can be resolved to the same pressure acting upwards over the area across the centre of the sphere - so we take the area as the Cross Sectional Area across the join.Area = PI * radius^2So to calculate the pressure use:Pressure = (Mass*Gravity) / (PI * radius^2)
Can centre of mass of a body can exist at point where there is no mass of the object?
Yes. For example, the center of mass of a hollow sphere would be at the empty center of that sphere.
A solid aluminum sphere has a mass of 88g Use the density of aluminum to find radius of sphere?
Density = mass / volume. You have the density of aluminum and the mass of the aluminum sphere. The volume of a sphere is 4/3*Pi*r^3. Therefore volume = 4/3*Pi*r^3 = mass / density. Solve for r, which is the radius of the sphere.
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.

How do you derive the moment of inertia of solid sphere?
mass moment of inertia for a solid sphere: I = (2 /5) * mass * radius2 (mass in kg, radius in metres)
What is the mass in grams of a sphere with 3cm radius if the mass of a steel sphere of a radius 2.5cm is 500g?
Vol(3)/Vol(2.5) = 33/2.53 = 1.23 So Mass(3) = 1.23*Mass(2.5) = 1.23*500 = 864 grams
What is the diameter of a copper sphere that has the same mass as a 8.00 8.00 8.00 cube of aluminum?
The diameter of the sphere is 19.6 cm.
How do you find mass of a sphere when only radius is given?
Volume of a sphere = 4/3*pi*radius3 Surface area of a sphere = 4*pi*radius2
How do you find the density of a sphere given its mass and radius?
Density = mass/ volume volume= 4/3(pie)(r^3) ***r= radius in meters** so find volume then divide mass by volume and there you go.
If a tunnel went to the core of Earth would you weigh less half way down to it because of all the mass above you?
Yes. If the sphere is homogeneous ... meaning that every speck of it has the same mass, density, etc. ... then it turns out that at any point inside the sphere, all the mass outside that radius cancels out. The sphere acts as if the outside part doesn't exist, and the gravitational field is what you'd expect from only the part of the sphere that's inside that radius.
What will be the mass of a body at the centre of the earth as compared to other places on the earth?
Mass is conserved which means that a body will have the same mass wherever it goes. But at the centre of a masive sphere the body has no gravity acting on it so its weight is zero. At an intermediated radius the force on it is obviously less than at the surface, and Isac Newton proved that a body at a given distance inside a sphere feels a gravitational force from a sub-sphere of radius equal the distance of the body from the centre. In other words the body feels no gravity from the shell outside its own radius.
How do you find the mass of a sphere with a radius of 4.7 mm and a length of 3.9mm?
First and foremost, you must know the density. Mass is the product of volumeand density (m=vd). Also, a sphere is specified by its radius alone. The "length"of a sphere should represent nothing more than its diameter, which is twice itsradius.==============================Answer #2:First of all, that's no sphere, since spheres don't have 'length'.Next . . . As written, the question has no answer, simply because the mass ofa sphere doesn't depend on its size. A hundred spheres can easily all have thesame size but a hundred different masses.
Two spheres are cut from a certain uniform rock One has radius 4.15 cm The mass of the other is six times greater Find its radius?
Provided they are the same thickness, the larger sphere will have a radius of 10.165cm
