Q1. A man pushes the lawn mower on a level lawn with a force of 240 N. If 40 percent of this force is directed downward, how much force is directed horizontally?
Q2. Two conducting wires a and b of circular cross-section have the same length and radii but are made from different metals. The resistivity of wire a is twice that of wire b. When these two wires are connected in equivalent to the same battery, describe the reasoning of the steps that allow you to find out which of these wires will consume the greater amount of power by warming up and dissipating this energy as heat.
