You purchased 5.2kg of apples from a store. You noticed that they used the smallest division of 4.2 g to weight them. What is the relative error of this weight measurement as a percentage. You want to calculate the area of your dorm which is in a rectangular shape. You measure the length and the width of the room as L= 4.8+(-.01) m, W= 4.4+(-.01) m. What is the absolute error in the area in m^2 units?

What is the approximate mass of air in a living room 4.3 m x 3.4 m x 2.8 m? The density of air is 1.29 kg/m³. Express your answer to two significant figures and include the appropriate units. HẢ ? Value Units т

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.

Please help. This problem involves finding the radius and volume of a platinum atom using its density. Thank you.

Why is the average density not a "good" measure of density in this experiment? Mass (kg) Volume(m^3) Density (kg/m^3) 1.16 0.001 1160 2.46 0.0023 1069.565217 5.16 0.005 1032 10.16 0.01 1016 13.66 0.0135 1011.851852         Its a good measure     The average does not account for the human errors in the measurements.     The average does not account for the random errors in the measurements.     The average does not account for the systematic errors in the measurements.
