1. The piston in the figure has a mass of 0.5 kg. The infinitely long cylinder is pushed upward at a constant velocity. The diameters of the cylinder and piston are 10 cm and 9 cm, respectively, and there is oil between them with v = 10⁻⁴ m^2/s and γ = 8,000 N/m³. At what speed must the cylinder ascend for the piston to remain at rest?

In addition, assume your house is the only one using electric power. At a substation the primary of a step-down transformer (turns ratio = 1:23) receives the voltage from the high-voltage transmission line. Because of your usage, a current of 51.1 mA exists in the primary of the transformer. The secondary is connected to the primary of another step-down transformer (turns ratio = 1:36) somewhere near your house, perhaps up on a telephone pole. The secondary of this transformer delivers a 240-V emf to your house. How much power is your house using? Remember that the current and voltage given in this problem are rms values.arrow_forward
