A stone is suspended in a tub of water with copper wire. Another stone of equal mass is suspended in kerosene with equal length of copper wire then

A wire of radius 5 mm is produced from a lump of copper. Another wire of the same mass but of diameter 1 cm is produced from another lump of copper. Determine the ratio of the resistances of the two wires.

The radius of a copper wire is twice that of a steel wire. One end of the copper wire is joined with one end of the steel wire and the same tensile force is applied on them . If the length of the copper wire increases by 1% , what will be the percentage increase in the length of the steel wire? Given Young's modulus of steel is twice that of copper.

A copper wire and a steel wire of the same length and same cross-section are joined end to end to form a composite wire. The composite wire is hung form a rigid support and a load is suspended form the other end. If the increses in length of the composite wire is 2.4mm . then the increases in lenghts of steel and copper wires are

When a certain weight is suspended to a long uniform wire its length increases by one cm. If the same weight is suspended to another wire of the same material and length but having a diameter half of the first one, the increase in its length will be

A suspended nano wire is a wire that is produced in………...

A mass m is suspended from a wire . Change in length of the wire is Deltal . Now the same wire is stretched to double its length and the same mass is suspended from the wire. The change in length in this case will become (it is suspended that elongation in the wire is within the proportional limit)
