In the calibration of an ammeter, using Faraday's law of electrolysis, the ammeter is kept constant at 1.2A (ampere). If 0.99g of copper is deposited in 40 minutes, find the correction to be applied to the ammeter. (Take Z = 0.00033gc^-1).

The car hoist allows the car to be driven onto the platform, after which the rear wheels are raised. if the loading from both rear wheels is 1380 lb, determine the force in the hydraulic cylinder ab. neglect the weight of the platform itself. member bcd is a right-angle bell crank pinned to the ramp at c. the force is positive if in tension, negative if in compression.
