A cell phone battery manufacturer claims that one of their batteries for a particular cell phone will outperform a competitor's equivalent brand. To establish this claim, a researcher selected samples of the two brands of batteries and perform accelerated tests on them in the lab under identical conditions. A random sample of 55 of the manufacturer's battery was selected and placed on test. A corresponding random sample of 55 of the competitor's battery was also put...

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...
