Rohit bought 2 1/4 metre of iron wire and 3 1/3 m of copper wire. (i) How much wire did he buy altogether? (ii) How much more copper wire is more than iron wire

Asha bought 3(1)/(4) m of cloth and Mrinal bought 2(2)/(5) m of cloth. How much cloth did they buy together?

An iron rod B of length 1 m and mass 1 kg is suspended with help of two wires as shwon in figure. The area of cross-section of iron wire is 0.3 cm^(2) and of copper wire is 0.6cm^(2) . In the above question, if Y_("iron"):Y_(Cu)=2:1 , then the ratio of extension produced in copper wire to iron wire is

IF the length of a copper wire is increased by 0.1%, show that the resistance of the copper wire will increase by 0.2%.

3 m long copper wire is stretched to increase its length by 0.3 cm. The lateral strain produced in the wire is,

The frequency ratio of two wires of copper is 2 : 3 if the diameter of the first wire is 0.6mm, the diameter of the other wire is -

A copper wire of length 1m is stretched by 1cm. Find the strain on the wire
