A U-tube is filled with water, and the two arms are capped. The tube is cylindrical, and the right arm has twice the radius of the left arm. The caps have negligible mass, are watertight, and can freely slide up and down the tube. If a 1 kg mass block is on the left cap, how much total mass must be placed on the right cap so that the caps equilibrate at equal height?

Density of Solids

The density of a substance refers to how much matter is present in a given amount of space. It is expressed as the ratio of the mass of the substance to its volume.

Inside the wall of a house, an L-shaped section of hot-water pipe consists of three parts: a straight, horizontal piece h = 28.0 cm long, an elbow, and a straight vertical piece l = 152 cm long (figure below). A stud and a second-story floorboard hold the ends of this section of copper pipe stationary. Find the magnitude and direction of the displacement of the pipe elbow when the coordinate system with it's origin at the elbow, the +x-axis to the right in line with the horizontal water flow is turned on, raising the temperature of the pipe from 18.0°C to 43.6°C. (Assume pipe and the +y-axis going upward.) 0.6568 Your response is within 10% of the correct value. This may be due to roundoff error, or you could have a mistake in your calculation.
