Question

A weight of 100 N is suspended by two wires made
of steel and copper as shown in the figure. Length
of steel wire is 1 m and copper wire is V3 m Find
the ratio of change in length of copper wire (Alc) to
change in length of steel wire (Als). Given Young's
modulus: Ysteel
Ysteel = 2 x 1011 N/m?
Ycopper = 1 x 1011 N/m².​

Answer 1

Explanation:

Strong acid is an acid that ionizes completely in aqueous solution. It always loses a proton (H+) when dissolved in water. Weak acid is an acid that ionizes partially in a solution. It gives off only a few of its (H+) atoms when dissolved in water.

A weight of 100 N is suspended by two wires made

of steel and copper as shown in the figure. Length

of steel wire is 1 m and copper wire is V3 m Find

the ratio of change in length of copper wire (Alc) to

change in length of steel wire (Als). Given Young's

modulus: Ysteel

Ysteel = 2 x 1011 N/m?

Ycopper = 1 x 1011 N/m²..
