What is the density of rod?
1. Center of mass for a linear density function. A rod has length 4 meters. At a distance meters from its left end, the density of the rod is given by δ ( x ) = 5 + 2 x g/m.
How do you find the density of a metallic rod?
The difference between the original volume and the final volume will give you the volume of the metal rod. By knowing the rod’s volume (V) and mass (m) you can calculate the density.
What is the density of the metal?

What is the density of the metal sample?
Sample problem: A solid has a mass of 128 g. It is a rectangular solid 1.0 cm by 2.0 cm by 3.0 cm. What is the density of the solid and what metal is it? Volume = length x width x height = 1 cm x 2 cm x 3 cm = 6 cm3 or 6 ml….
| element | density (g/cm3) | appearance |
|---|---|---|
| Zinc | 7.14 | bluish white, metallic |
How do you find the average density of a rod?
The linear density of a rod of length m is given by p(x) = 1/√x, in grams per centimeter, where x is measured in centimeters from one end of the rod. Find the mass of the rod. The mass of part of a wire is x(1+√x) kilograms, where x is measured in meters from one end of the wire.
How do you find the density of a metal?
We calculate the density of metal by dividing the mass of the object by its volume. Suppose the mass of the object is 7.952 pounds and its volume is 28 cubic inches then its density would be 0.284 per cubic inch.
How do you find the mass of a rod given density?
Figure 2.48 We can calculate the mass of a thin rod oriented along the x -axis by integrating its density function. If the rod has constant density ρ , given in terms of mass per unit length, then the mass of the rod is just the product of the density and the length of the rod: ( b − a ) ρ .
What is the formula for linear density?
The Dimensional Formula of Linear Mass Density = M1L-1T0. The SI unit of Linear Mass Density is kg m-1.
How to find the density of a metal rod?
A metal rod is 50cm long. Its linear density at the point x cm from the left end is given by the equation p(x)=1/(100-x) gm/cm. Find the mass and center of mass for the rod. 2. Homework Equations.
