What else can I help you with?
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?
There are several methods:From geometry and the formula for the volume of a sphere:Assuming the marble is a perfect sphere, the radius of the marble is one-half of the diameter, or width of the marble. Use the formula for volume,V = (4/3) pi r3where pi is approximately 3.1416 and can usually be found on a scientific calculator. R is the radius as mentioned before. The formula in text is "four-thirds times pi times the radius cubed." Make sure to do the cubing first.From the displacement the marble causes in water or other liquidyou can measure the volume of a marble by filling up a glass beaker to whatever amount you'd like,then you would see how much the water went up.and that would be you answerFrom the density of the marbleWeigh the marble and determine typical density of glass from available tables. As the density of the marble is found by the formulaDensity=mass/volume,divide the mass in grams by the density in gm/cm3 to determine the volume in cm3.
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.
What is the moment of inertia of a solid sphere?
The moment of inertia of a solid sphere is given by the formula (2/5) m r2, where m is the mass of the sphere and r is the radius of the sphere.
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?
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).
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.
How do you find that mass of a sphere?
To find the mass of a sphere, you can use the formula ( m = \rho V ), where ( m ) is mass, ( \rho ) is the density of the sphere's material, and ( V ) is the volume. The volume of a sphere is calculated using the formula ( V = \frac{4}{3} \pi r^3 ), where ( r ) is the radius of the sphere. Once you have the volume, multiply it by the density to obtain the mass.
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.
What is the mass of a sphere of radius 4cm?
To find the mass of a sphere, you need to know its density in addition to its volume. The volume ( V ) of a sphere can be calculated using the formula ( V = \frac{4}{3} \pi r^3 ). For a sphere with a radius of 4 cm, the volume would be approximately 268.08 cm³. If you provide the density of the material the sphere is made of, the mass can be calculated using the formula ( \text{mass} = \text{density} \times \text{volume} ).
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
