1) Mercury (Hg) can be used in a barometer to measure air pressure, based on how tall a column of mercury can be supported by the pressure of the atmosphere or another gas sample. The barometric reading taken at Skyline College on a specific day was 743.8 mm Hg. If the interior circumference of the tube holding the mercury is 9.82 mm, what is the mass of mercury in the tube (above the pool of mercury)? The column may be treated as a cylinder. Mercury has a density of 13.55 g/mL.

2) What is the length (in cm) of the side of an iron ingot (rectangular box) that has a mass of 4.578 kg and has width = height = 5.00 cm

3) What will be the final volume when a 98.356-g sample of lead (Pb) shot is added to a graduated cylinder holding 24.7 mL of water?

Calculate the partial pressure of O2 (P02, mm Hg) in dry air in Arcata (sea level- assume atmospheric pressure of 760 mm Hg). Arcata air never gets fully dry. Assume 90% humidity at 15°C (saturated water vapor pressure at 15°C=12.8 mm Hg) and calculated the actual partial pressure of O2 in Arcata air.

assume the radar signals of 10 GHz are used to measure the rotation rates of Mercury and Venus. Using the Dopper effect, determine the relative shifts in frequency for signals returning from the approaching and receding limbs of each plant. Answers are 101 Hz and 60.4 Hz - need to show the work though.

1. Air pressure refers to how the weight of air above a given place is distributed over the area taken up by the place. The weight of air deals with the way gravity pulls the air toward the ground and how much air is above the place. Is the amount of air above a square foot of ground in Edmond more or less than the amount of air above a square foot on top of the Devon Tower in Oklahoma...

Can a low barometer reading be used to predict maximum wind speed of an approaching tropical cyclone? For a random sample of tropical cyclones, let x be the lowest pressure (in millibars) as a cyclone approaches, and let y be the maximum wind speed (in miles per hour) of the cyclone. x 1004 975 992 935 979 926 y 40 100 65 145 82 153 (a) Make a scatter diagram of the data and visualize the line you think best...
