1. A 45.0-kg sample of ice is at 0.00* C. How much heat is needed to melt it? For water Lf = 334,000 J/ kg and Lv = 2.256 x 106 J/kg. . Consider an object undergoing SHM, as described by the equations x=(2.0)cos(5.0t), where tis in seconds. what is the period of this SHM? . A Jaguar X8 convertible has an eight-cylinder engine. At the beginning of its compression stroke, one of the cylinders contains 500 cm\" 3 of air at atmospheric pressure (1.01x10"5 Pa) and a temperature of 27.0C. At the end of the stroke, the air has been compressed to a volume of 50.0 cm\"3 and the gauge pressure has increased to 2.0x10"6 Pa Compute the final temperature
