**Moment of Inertia Sphere Georgia State University**

For mass M = kg and radius R = cm the moment of inertia of a solid sphere is I(solid sphere) = kg m 2 and the moment of inertia of a thin spherical shell is... Alternatively, place the sphere in a graduated cylinder half filled with water; the displacement of the water is equal to the volume of the sphere. Weigh the sphere, and calculate the density: Have students drop the ball into the fluid, timing the ball as it falls a measured distance.

**Electrostatic energy Home Page for Richard Fitzpatrick**

Answer #1: Mass is the product of volume and density. You can find the volume of a sphere with a radius of four (regardless of the unit of measure) usingv=4/3pi(r 3 ).... Ball Weight and Density How much will a ball of a given diameter in a certain material weigh? The answer is calculated by multiplying the volume of the ball by the density of the material.

**How to work out the mass of a sphere? Yahoo Answers**

Alternatively, if the density of a substance is known, and is uniform, the volume can be calculated using its weight. This calculator computes volumes for some of the most common simple shapes. Sphere. A sphere is the three-dimensional counterpart of the two-dimensional circle. It is a perfectly round geometrical object that mathematically, is the set of points that are equidistant from a canesten pessary how to use 17/03/2010 · Well, using that sentence you can't. Area is a two-dimensional value, and density deals with a three-dimensional value (volume). However, if you've been given the surface area of an object, then you can calculate the volume of that object, at which point you can calculate mass.

**Density Chemistry Socratic**

The electric field of a point charge Q can be obtained by a straightforward application of Gauss' law. Considering a Gaussian surface in the form of a sphere at radius r, the electric field has the same magnitude at every point of the sphere and is directed outward. how to work out triceps brachii Divide the mass of the sphere by the volume of the sphere. For example, if the mass were 10 lbs. and the volume was 2 cubic inches, the density would be 5 lbs. per cubic inch. For example, if the mass were 10 lbs. and the volume was 2 cubic inches, the density would be 5 lbs. per cubic inch.

## How To Work Out Density Of A Sphere

Find the density of the sand. Give your answer in kilograms per cubic metre. [3 marks] Question 7. (AQA June 2005 Intermediate Paper 1 NO Calculator) The diagram shows a cylinder. The diameter of the cylinder is 10 cm. The height of the cylinder is 10 cm. (a) Calculate the volume of the cylinder. Give your answer in terms of π. [3 marks] Twenty of the cylinders are packed in a box of height

- The greek symbol pho typically denotes electric charge, and the subscript V indicates it is the volume charge density. Since charge is measured in Coulombs [C], and volume is in meters^3 [m^3], the units of the electric charge density of Equation [1] are [C/m^3].
- Some of this might be fiction, but Archimedes' idea to calculate the volume of an object and its density if you know the object's weight was fact. For a small object, in the lab, the easiest way to do this is to partly fill a graduated cylinder large enough to contain the object with water (or some liquid in which the object won't dissolve). Record the volume of water. Add the object, being
