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
How do you find the volume of a marble?
To find the volume of a marble, you would use the formula for the volume of a sphere, which is V = (4/3)πr^3, where V is the volume and r is the radius of the marble. Measure the diameter of the marble and divide it by 2 to get the radius. Then, plug the radius into the formula to calculate the volume of the marble in cubic units.
What is the relationship between Moment of inertia and radius of gyration?
I believe it is I = mk^2 where k is radius of gyration and m is mass.
If the moment of inertia of a ring of mass M and radius R .what is its diameter?
Its diameter is 2R, whatever the mass.
How do you find area when given width and mass and density?
Density = Mass/Volume so Volume = Mass/Density. Therefore the Volume can be calculated. Volume = Area [of cross section] * Width So Width = Volume/Area.
The sphere is made of aluminum and its mass is 26 kg. 1) What is the radius of the sphere?
To find the radius of the aluminum sphere, you need to know its density. Without density information, it's not possible to calculate the radius just from the mass given.
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.
How do you find mass and volume if given radio and density?
Not sure how a radio can help. If you are given the radius (including units) of a sphere, the volume is 4/3*pi*r3 cubic units. Then mass = density*volume, in the appropriate units.
Density of a sphere?
The density of a sphere can be calculated by dividing the mass of the sphere by its volume. The formula for the volume of a sphere is (4/3)πr^3, where r is the radius of the sphere. By knowing the mass of the sphere and its volume, you can determine its density as mass divided by volume.
A solid aluminum sphere has a mass of 88g Use the density of aluminum to find radius of sphere?
The density of aluminum is about 2.7 g/cm³. To find the radius of the sphere, you first need to calculate the volume of the sphere using the mass and density formula (volume = mass/density). Next, use the formula for the volume of a sphere (4/3 * π * radius^3) to solve for the radius.
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.
Find the density of the nucleus of an iron atom with a radius of 3.555Fm and an atomic mass of 56?
To find the density of the nucleus, we first need to calculate the volume of the nucleus. The volume of a sphere is given by V = 4/3 * π * r^3, where r is the radius of the nucleus. Once we have the volume, we can divide the mass of the nucleus (which is equal to the atomic mass) by the volume to find the density. Density = mass / volume. Substituting the given values, we can calculate the density accordingly.
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
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
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 radius of a sphere based on the weight in pounds?
You need to know if the sphere is solid or hollow. You also need the "density" in terms of pounds weight per unit volume. Then Volume = Mass/Density And Radius = cuberoot[3*Vol/(4*pi)]
