Calculate the terminal velocity for a pollen grain falling through the air using the drag force equation. Assume the pollen grain has a diameter of 7 µm and a density of 0.3 g/cm3. If this grain is released from the top of a tree (height 11 m), estimate the time it will take to fall to the ground. Hint: The pollen grain will reach its terminal velocity very quickly and will have this velocity for essentially the entire motion. Your...
The absolute pressure at the bottom of a liquid store tank that is vented to the atmosphere is given by: Pabs,bottom = ρgh + Poutside Where: Pabs,bottom = the absolute pressure at the bottom of the storage tank (Pa)ρ = liquid density (kg/m3)g = acceleration due to gravity (m/s2)h = height of the liquid (m)Poutside = outside atmospheric pressure (Pa) Find Pabs,bottom in SI units if ρ = 1000 kg/m3, g = 32.2 ft/s2, h = 7 yd, and Poutside = 1 atm• Here are some tips to help you get started:o Remember your comment section and variable definitions o Use...
Can someone please help me with this with step by step clarification. I keep getting the wrong answers! Thank you!! 3. 0/1 points | Previous Answers SerCP11 1.5.P.028.MI. My Notes A house is 58.0 ft long and 32 ft wide, and has 8.0-ft-high ceilings. What is the volume of the interior of the house in cubic meters and cubic centimeters? Use the given length, width, and height to calculate the volume and then convert to the units asked for. m3...
Part C Iron has a density of 7.86 g/cm (1 cm = 1 mL). Calculate the volume (in dL) of a piece of iron having a mass of 4.25 kg . Note that the density is provided in different units of volume and mass than the desired units of volume (dL) and the given units of mass (kg). You will need to express the density in kg/dL (1 cm = 1 mL) before calculating the volume for the piece of...
a) Suppose that 1 g of dry soil is mixed vigorously with 100 mL of 0.5 M ammonium acetate solution. The soil and water mixture is filtered to remove the soil. The concentrations of calcium, magnesium, potassium, and hydrogen ions in the filtrate are measured. The concentrations of the cations found in the extraction solution are as follows: Ca2+-25.8 μg/mL, Mg2 3.4 ug/mL, K -2.2 ug/mL. Calculate the CEC of the soil. This is the same problem from Discussion 2....

10 10 10-6 In micro You can use these relationships to create equalities and conversion factors. For example, the prefix dea is denoted with a d and is associated with a factor of 10- If you were to apply this profix to liter, you would obtain the equality 1 dL -10 L. This could be used to create two conversion factors: 1 dL 10-1 L 10-1 The conversion factor used will depend on whether the final unit should be in...
An insulated Thermos contains 170 cm3 of hot coffee at 82.0°C. You put in a 13.0 g ice cube at its melting point to cool the coffee. By how many degrees has your coffee cooled once the ice has melted and equilibrium is reached? Treat the coffee as though it were pure water and neglect energy exchanges with the environment. The specific heat of water is 4186 J/kg·K. The latent heat of fusion is 333 kJ/kg. The density of water...
Air a. What is the volume of air in the room where you are right now? (You can measure the length, width, and height of the room with a measuring tape, or you can estimate these quantities. Just make sure you convert your answer to SI units.) b. What is the temperature in this room? (in SI units) c. Look up the current barometric pressure in your area, and convert it to SI units. d. Use the information from steps...
An ice cube of mass 9.0g is added to a cup of coffee, whose temperature is 90.0 °C and which contains 120.0 g of liquid. Assume the specific heat capacity of the coffee is the same as that of water. The heat of fusion of ice (the heat associated with ice melting) is 6.0kJ/mol. Find the temperature of the coffee after the ice melts. Use the equation given in the lab manual on page 86. Ignore the + (CC) (AT)...
