The period of a pendulum varies directly as the square root of the length of the pendulum and inversely as the square root of the acceleration due to gravity. find the period when the length is 144 cm and the acceleration due to gravity is 980 cm per second squared, if the period is 7pi seconds when the length is 289 cm and the acceleration due to gravity is 980 cm per second squared.

An insulated thermos contains 148 g of water at 72.7 Ėc. you put in a 11.7 g ice cube at 0.00 Ėc to form a system of ice + original water. the specific heat of liquid water is 4190 j/kgā¢k; and the heat of fusion of water is 333 kj/kg. what is the net entropy change of the system from then until the system reaches the final (equilibrium) temperature?
