An incandescent lamp of 60W is connected to a 120V outlet. What is the electrical resistance of the lamp? And what is the electric current passing through the lamp? How can we calculate the energy consumed by the lamp in one hour of operation? Hint: Use the formulas P = V x I and P = R x I² to calculate the electrical resistance and the electric current passing through the lamp, respectively. To calculate the consumed energy, use the formula E = P x t, with t being equal to one hour (3600 seconds).Answer sheet:

João is helping his father fill the home pool, which is rectangular and has the following dimensions: 8 meters in length, 4 meters in width, and 1.5 meters in depth. They are using a hose with a constant flow rate of 20 liters per minute. Considering that the pool was completely empty and there was no water wastage in the process, answer: (a) What is the total volume of the pool in liters? (b) How long, in hours, will it take to completely fill the pool with the hose? (c) If the water in the pool had the mentioned constant flow rate, but drained through an opening of the same size as the hose, how long would it take for the pool to completely empty?
