- Please help. This problem involves finding the radius and volume of a platinum atom using its density. Thank you.The hydraulic diameter of a rectangular duct is calculated using the equation D = 4, where Dr is the hydraulic diameter, A is the cross-sectional area of the duct and p is the perimeter of the duct. If the dimensions of the rectangular duct are a = 26 cm+0.4 mm, and b = 33 cm +1.3 mm, what is the uncertainty of D, in percentage format? Enter the answer as a numerical value without any sign. Retain 3 significant figures. aAn Olympic-size swimming pool is 50 m long, 25 m wide, and 2 m deep. In terms of volume, this pool, when full, holds how many kilogallons of water? Use the following equivalences: 1 gallon = 3.8 L 1 kilogallon = 103 gallon 1 L = 103 mL for water: 1 mL = 1 cm3 1 m = 100 cm [Numerical Problem: Just write the numerical answer without units. Express your answer to 2 significant figures in standard notation]
- Assume it takes 9.00 min to fill a 35.0-gal gasoline tank. (1 U.S. gal = 231 in.³) (a) Calculate the rate at which the tank is filled in gallons per second. gal/s (b) Calculate the rate at which the tank is filled in cubic meters per second. m³/s (c) Determine the time interval, in hours, required to fill a 1.00-m³ volume at the same rate. (1 U.S. gal = 231 in.³)the average density of an atom is approximately 103 kg/m3. The nucleus of an atom has a radius about 10-5 times that of the entire atom, and contains nearly all the mass of the atom. What is the approximate density, in kilograms per cubic meter, of a nucleus?The density of pure solid copper is 8.93 grams per milliliter. What volume does 7 kilograms of copper occupy?
