Question:

1. Two identical wires are 125 cm and 375 cm long, respectively. The first wire is broken by a force of 489 N. What force is needed to break the other?

2. The cross-sectional area of a wire is 2.50 x 10–3 cm2 and its tensile strength is 1.00 x 10–3 cm2. What force will break the wire?

3. A spring having a force constant of 1.25 N/cm is stretched through a distance of 11.5 cm. How much work is required to stretch the spring?
