What is the density of a rubber stopper in G cm3?
1.10 g/cm3
The density of the rubber stopper is 1.10 g/cm3 1.10 g/cm 3 .
What is the volume of the stopper?
The volume of a rubber stopper is 9.35 mL and the reference value for the density of rubber is 1.33 g/mL.
How heavy is a rubber stopper?
21-1/4 Oz.
How much does a rubber stopper weigh in grams?
“A rubber stopper, which as a mass of m=14.5 grams, is tied to the end of a string which is threaded through a glass tube.

How do you find the period in circular motion?
The distance around a circle is equivalent to a circumference and calculated as 2•pi•R where R is the radius. The time for one revolution around the circle is referred to as the period and denoted by the symbol T. Thus the average speed of an object in circular motion is given by the expression 2•pi•R / T.
What is the density of a stopper?
The theoretical density of the rubber stopper was greater than 1.00 g/mL, so the measured mass was bigger than the measured volume. My calculated density for the rubber stopper was 1.29 g/mL, with a 7.5% error.
How to calculate the mass of a rubber stopper?
Obtain the mass by weighing the rubber stopper and a small weight or the mass of small number of washers (be sure the washers are all the same size) Practice whirling the rubber stopper until you can keep the top clip a short distance below the bottom of the tube while the stopper whirls.
How to calculate the force of a hanging mass?
Compute the Force exerted by the hanging mass (weights or washers): weight = Fg = (mhanging mass) (9.8m/sec2) Change the hanging mass. Repeat steps 1-10. Change the hanging mass again. Repeat step 1-10
Is the mass on the bottom of the string linear?
If you keep the mass on the bottom of the string (M 2) constant, then there is a relationship between the length of the string and the period – I am not saying it is a linear relationship. So, here is what you are going to do:
