A 10.0-m-long copper wire with cross-sectional area 1.25 × 10–4 m2 is bent into a square loop, and then connected to a 0.25-V battery. The loop is then placed in a uniform magnetic field of magnitude 0.19 T. What is the maximum torque that can act on this loop? The resistivity of copper is 1.70 × 10–8 Ω·m.

Aspring is used to stop a 50-kg package which is moving down a 20º incline. the spring has a constant k = 30 kn/m and is held by cables so that it is initially compressed 50 mm. knowing that the velocity of the package is 2 m/s when it is 8 m from the spring and neglecting friction, determine the maximum additional deformation of the spring in bringing the package to rest.
