Question

1. Andy's backyard pool (above ground) has a small hole of area 10 mm² located 0.8m below the surface of the water. What is the volumetric flow rate through the hole?

2. Mr. Potato Head (m = 1.5 kg) is left under the back window of the car. He is heated by the sun so that he absorbs 90 kJ of energy, and his temperature rises by 15 ^oC. What is the specific heat of Mr. Potato Head? Use `K' in your units, not `^oC'.

3. In the hot attic (34 ^oC), Emporer Zurg is 27 cm tall. But when he goes into an air conditioned room (24 ^oC), he is only 26.6 cm tall. What is his coefficient of thermal expansion? Again, use `K' in your units.

Thank you for your help
