The Really Big Dam is 1000 feet wide, holds back a depth of 60 feet of water, and the lake behind the dam extends back one quarter of a mile. The Very Big Dam is also 1000 feet wide, holds back a depth of 50 feet of water, and the lake behind the dam extends back for 2 miles. If the dams were constructed in the same way, which dam had to be constructed to be strongest? (Assume the water levels do not vary seasonally.)

Standing side by side ,you and a friend step off a bridge at different times and fall for 1.6s to the water below. your friend goes first, and you follow after he has dropped a distance of 2.0m. when your friend hits the water, is the seperation between the two of you 2.0m or more than 2.0m? verify your answer with a calculation.

Acommercial refrigerator with refrigerant-134a as the working fluid is used to keep the refrigerated space at -35°c by rejecting waste heat to cooling water that enters the condenser at 18°c at a rate of 0.25 kg/s and leaves at 26°c. the refrigerant enters the condenser at 1.2 mpa and 50°c. if the compressor consumes 3.3 kw of power, determine (a) the mass flow rate of the refrigerant, (b) the refrigeration load, (c) the cop, and (d) the minimum power input to the compressor for the same refrigeration load.
