3) This is not a web query, but an actual activity involving measurement. Measure the flow rate and time to fill a bathtub. How much energy is used for a bath? Hint: To do this calculation, use the same temperatures and water tank efficiency parameters used by the author in his shower example. This way, we control the variables for a more meaningful comparison. Describe your procedure and state clearly all assumptions made for your bath calculations. a) Compare the energy used for a bath and a shower. b) What factors would change this comparison, from person to person, and how
