What is the mass of a cylinder of lead with a radius of 1 centimeter and a height of 3 centimeters, given that the density of lead is 11.4 (g)/(cm^(3))?
Which of the followings is the volume of a metal cylinder with 40 mm for diameter, 3.0 cm for height?
The radius of a copper (Cu) atom is roughly 1.3 ×10−10 m. How many times can you divide evenly a 446.7−cm long piece of copper wire until it is reduced to two separate copper atoms? (Assume there are appropriate tools for this procedure and that copper atoms are lined up in a straight line, in contact with each other. Round off your answer to an integer.)
