Physics 2 A standard D cell battery can supply 25 mA at 1.5 V for about 300 hours, and its internal resistance is about 1 Ω. A lift is powered by a battery such that it is 50% efficient and is being used to lift a 60-kg object that is initially on the ground. When the winch is set to a very slow speed, the load resistance is much greater than the internal resistance of the battery. The greatest speed...
Consider the following reaction: 2 Ag+(aq) + Cu(s)->2 Ag(s) + Cu2+(aq) Ecell^o = +0.46V Suppose an external power source is applied with a current of 1.50 A such that the reaction is reversed and electrolysis occurs. (a) If the current is applied for 2.00 hours, how many grams of Cu(s) could be recovered? What is the minimum mass of the silver electrode required to recover this mass of copper? (b) What is the minimum amount of work that must be...
