Ned is emptying the dishwasher. He removes a 0.20 kg glass that has an initial temperature of 30C (c = 840 J/kgC). Into it he pours 0.10 kg of diet soda (c = 4200 J/kgC) which comes out of the fridge at 5C. Assuming no external heat loss, what is the final equilibrium temperature of the glass of diet soda?

Use the ratio form of kepler’s third law, = , and the data provided to determine the time it takes mars to orbit the sun. round your answer to the nearest tenth. earth’s orbital period = 1.0 earth year earth’s distance from the sun = 1.0 au mars’s distance from the sun = 1.5 au it takes mars about ⇒ 1.8 earth years to orbit the sun.
