A piece of 24.5 m long was cut from a piece of copper wire 35 m long and weighing 840 g

A piece of 24.5 m long was cut from a piece of copper wire 35 m long and weighing 840 g. What is the mass of the remainder?

First, we find the length of the remainder of the wire:

35 – 24.5 = 10.5 m.

Let’s find the mass of one meter of wire. To do this, we divide the total weight of the wire by its length:

840/35 = 24 g.

We can now find the mass of the remainder of the wire. Just multiply its length by the mass of one meter:

10.5 * 24 = 252 g.

Answer: The mass of the remainder of the wire is 252 grams.
