1) You want to find the volume of a metal sphere (Note: the formula for the volume of a sphere is V = 4㎡ , where r is the radius of the sphere). You measure the radius of the sphere to be r-2.18 cm, with a measurement uncertainty of + 0.02 cm. What is the volume of the sphere as well as the corresponding uncertainty of the calculated volume?

1. An experiment is performed in the lab, where the mass and the volume of an object are measured to determine its density. Two completely different valid methods are used. Each experimental method to measure the density is performed, two considerable sets of data are taken on each and the results are compared. The results of the density measurement by each method should be ... a. dependent on the mass and the volume of the object b. completely different, because...

To measure the density of a rectangular object, an experimenter measures the object's volume and mass. The volume is given by the formula V = LWH, where L is the length, W is the width, and H is the height. The density is given by p = m/V, where m is the object's mass. If the measurement of the mass is uncertain by 2%, and each of L, W and H is uncertain by 4%, what is the uncertainty, in...

Find the densities with error:
Calculate the volumes, V, and V2, and densities, ρ, and f, required in the tables below. You need to determine the correct uncertainty, e.g. AL, for each instrument. Check with your instructor. Also, read the Introduction in this experimental procedure.

To determine the volume of a sphere, you measure its diameter using a ruler an obtain a value of 15.2 mm for the diameter. Using this diameter, you convert the diameter to units of centimeters by dividing the radius by 10 mm/cm and then you divide the diameter by 2 to obtain the radius (r). You then use the equation V = 4/3rr to obtain the volume of the sphere. To determine the mass, you measure the mass on a...

PRE-LAB Questions: 1) You use a force sensor to measure the weight of an object 10 times, and get the following values: 2.8, 2.6, 2.9, 3.1, 2.4, 2.9, 3.2, 2.5, 2.7, 3.0, where all ten values are in units of N. What is the mean weight of the object, as well as the measurement uncertainty of the weight? 2) You measure the mass of the object from question 1 to be m = 300.8 g with an uncertainty of ±...

You have two objects made of the same substance. Object 1 is a cube with a mass of 465.5 g. You measure the side of the cube using a ruler and find it to be 3.17 cm. Object 2 is a sphere with a mass of 232.8 g. You find the volume of the sphere using water displacement. The volume of the water in a graduated cylinder initially is 120.0 mL, and when the sphere is added the new volume...
