A glass full of water placed on a standard kitchen scale weighs 0.7 Kg. If the scale is placed on the bottom of a swimming pool with the same glass on it, will the scale measure more or less than 0.7 Kg. Explain your answer.
Homework Answers
Scale will measure lesser than 0.7 kg when glass placed on the bottom of swimming pool.
Reason Glass of water will experience an upward buoyancy force which causes loss in weight measured by sacle.

1) The Bernoulli equation is valid for inviscid flow. What term(s) in the energy balance are assumed to be zero? 2) A glass full of water placed on a standard kitchen scale weighs 0.7 Kg. If the scale is placed on the bottom of a swimming pool with the same glass on it, will the scale measure more or less than 0.7 kg. Explain your answer.

Example 3: Consider a glass that is half full of water that has a card placed over the top and is inverted. Assuming the air gap has a pressure that is less than atmospheric pressure, the water should stay in the glass. If that pressure is 99% of Ptrn, what is the max height of water that could be in the glass? (Hint: Start by using force balance

A 32.5-g glass thermometer reads 24.1 ∘C before it is placed in 115 mL of water. When the water and thermometer come to equilibrium, the thermometer reads 41.8 ∘C. Ignore the mass of fluid inside the glass thermometer. The value of specific heat for water is 4186 J/kg⋅C∘, and for glass is 840 J/kg⋅C∘. Part A What was the original temperature of the water? Express your answer using three significant figures. T T = nothing ∘C SubmitRequest Answer Provide Feedback...
