Question

For the following questions, you will need these quantities:

Local acceleration due to gravity, g = 9.80 m/s2

Density of water = 1.00 g/cm3

Density of copper = 8.96 g/cm3

Density of air = 0 (Note, this isn't true, but we'll use this approximation for these questions, and in the lab.)

Answer all questions to the fourth decimal place.

1.What is the volume of a cylinder that is 8.72 cm long and has a diameter of 7 mm?

Answer in cm^3.

2.If the cylinder in Question 1 is made of copper, what is its mass?

Answer in grams.

3.If the copper cylinder in Questions 1 & 2 is held in air by a string, how much tension is in the string?

Answer in newtons.

4.If the cylinder in Questions 1 & 2 is held in water by a string, how much buoyancy acts on the copper cylinder?

Answer in millinewtons (mN).

5.For the cylinder in Question 4, how much tension is in the string?

Answer in newtons.
