4) (From question above) What is the force of buoyancy on the metal block? a) 95N b) 7.5N c) 2.5N d) 1,000N 5) A decrease of 20 degrees in the Celsius scale is equivalent to a decrease of degrees Fahrenheit, and a decrease of Kelvin a) 20,180 b) 36,20 c) 16.7,20 d) 20,36 6) According to the Equation of Continuity, blood speed increases as blood flows from a healthy region of an artery and into a stenosis (i.e. v2?>v1? from the figure). According to Bernoulli's principle, when comparing the blood pressure P?2? of the stenosed region versus the pressure P1? of the healthy region, one should find P1?>P2?. If v1?=0.20m/s,v2?=0.40m/s, and P1?=120mmHg, what is P2? ? (assume blood mass density =1060kg/m3 ) a) 80mmHg b) 180mmHg c) 56mmHg d) 30mmHg A 18.2 ?L tank of carbon monoxide gas ( CO ) is at a pressure of 9.20×105Pa and temperature of 17.2?C. Find the following 4 questions: (Note 1L=10?3m3 ) 7) Use the ideal gas law to calculate the number of moles of gas in the tank. a) 811mol b) 45.9mol c) 4×1013mol d) 6.94mol
