- 11. Explain how hot air balloons are lifted and ships float.need fast pleaseEstimate the average question estimate the average blood pressure in a person’s foot if the foot is 1.03 m below the aorta, where the average blood pressure is 101 mmHg. For the purposes of this estimate assume the blood isn’t flowing. The density of blood is 1060 kg/m cubed. Give answer is units of mmHg.
- 14. Liquids have a definite shape but indefinite volume. (True/False)You shopping at the local grocery store and notice that tide laundry detergent costs $5.88 for 46 fl 0z and $12.10 for 90 fl 0z calculate and identify which is a better buy5. A cube of ice Lo on each side is dropped into a beaker of water. Initially when the ice is first put into the water the water level is Vo. The water level is the volume of water read on the side of the beaker, it includes the volume of water plus the submerged volume of the ice (Draw a picture of this). The ice floats in the water and it is NOT completely submerged. "water" is liquid water "ice" is water ice Pwater> Pice What is the initial Water level? Your answer should be in terms of the density of water, the density of ice, Lo, and the initial amount of water in the beaker Vwater (initial). b. A little while later the ice has melted. It is now L₁ =Lo/4 on each side. What is the water level in the beaker? Later still the ice has completely melted. What is the water level in the beaker? a. C.
