The linear density of a rod of length 4 m is given by p(x) = 8 + 2Vx measured in kilograms per meter, where x is measured in meters from one end of the rod. Find the total mass of the ra kg
The density of ordinary air is 1.19 g/L. What is the mass, in kilograms, of the airin a room that measures 14.5 ft x 16.5 ft x 8.0 ft?(Hint: Density is defined as d= m/v, so you need to find the volume of the roomand solve for the mass in the density equation. Make sure you do the appropriateconversions to carry out your operations. Use the correct number of significantfigures to express your answer).
You want to calculate the volume of air that occupies a standard volleyball. You measure the diameter of the balloon with a ruler graduated to the millimeter. The measurement is rather difficult to take, but you trust that the correct measurement is somewhere between 20.8 cm and 20.9 cm. Calculate the volume of air inside the balloon as well as the uncertainty of this value and give the answer in cm^3.
