A piece of copper is 1 meter long and has a density of 8.8g. If you cut the wire exactly in half, what is the density of one of the pieces

4.4g for 1/2 of a meter long piece of copper

The density of something doesn't change if you cut it in half or do things like that to it.

For example, a litre of water has the same density as a glass of water (as long as they are at the same temperature). It's a property of the material.

Also, the unit of density should be g/cm^3 not g.

To find the density of one of the pieces, we'll need to use the formula for density:

Density = Mass / Volume

Since we are given the length of the wire and the density, we can find the mass by multiplying the density by the length:

Mass = Density * Length

In this case, the length of the wire is 1 meter, so the total mass of the wire is:

Mass = 8.8 g/cm^3 * 1 m = 8.8 g

Now, when you cut the wire exactly in half, each piece will have half the length of the original wire. So, the length of each piece will be:

Length of each piece = 1 m / 2 = 0.5 m

Now, to find the density of one of the pieces, we'll divide the mass of the wire by the volume of one of the pieces. The volume of a straight piece of wire can be calculated using the formula:

Volume = Area * Length

Since we are working with a cylindrical wire, the cross-sectional area is constant. The cross-sectional area of a cylinder is given by:

Area = π * r^2

However, we haven't been given the radius of the wire. So, we can't determine the actual cross-sectional area. Without this information, we can't calculate the volume and therefore, the density of one of the pieces.

In conclusion, without knowing the radius of the wire, we cannot determine the density of one of the pieces after it is cut in half.
