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 water flow is turned on, raising the temperature of the pipe from 18.0°C to 43.6°C. (Assume a coordinate system with it's origin at the elbow, the +x-axis to the right in line with the horizontal 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. Carry out all intermediate results to at least four-digit accuracy to minimize roundoff error. mm 79.57 magnitude direction v • (clockwise from the +x-axis)

Light bulb 1 operates with a filament temperature of 2700 K, whereas light bulb 2 has a filament temperature of 1700 K. Both filaments have the same emissivity, and both bulbs radiate the same power. Find the ratio A1/A2 of the filament areas of the bulbs.

Many hot water heating systems have a reservoir tank connected directly to the pipeline, to allow for expansion when the water becomes hot. The heating system of a house has 76 m of a copper pipe whose inside radius is 9.5 x 10^ -3 m. When the water and pipe are heated from 24 Celcius to 78 Celcius, what must be the minimum volume of the reservoir tank to hold the overflow of water?

By how many degrees Celsius do you need to raise the temperature of a copper rod in order to increase its length by 5%? The linear expansion factor for copper is 17×10-6 /°C.

A student walking to class on a cold day (To = -1 °C) find a silver ring with an inner diameter of D = 1.7 cm. The silver has a coefficient of linear expansion of α = 19.5 × 10-6 1/C. What is the change in diameter in mm if Tb=37 C ?

At room temperature(25°C), a 5.000-mm-diameter tungsten pin is too large for a 4.999-mm-diameter hole in a nickel bar. To what temperature must these two parts be heated in order for the pinto just fit? (coefficient of thermal expansion for nickel = 12.7 × 10^-6 mm/mm°C, coefficient of thermal expansion for nickel = 4.5 × 10^-6 mm/mm°C)

The ends of a cylindrical copper rod are maintained at two different temperatures. The rod conducts heat from one end to the other at a rate of 41 J/s. At what rate would a copper rod three times as long and one-third the diameter conduct heat between the same two temperatures? O 4.6 J/s O 1.5 J/s O Same rate O 13.7 J/s O 123 J/s

Water is boiling in an aluminum pan placed on an electrical element on a stovetop. The sauce pan has a bottom that is 0.800 cm thick and 14.0 cm in diameter. The boiling water is evaporating at the rate of 1.00 g/s. What is the temperature difference across (through) the bottom of the pan?

The primary and secondary mirrors of a space telescope are assembled using zerodur spacers in an engineering laboratory in which the room temperature is 20 degrees C. In space the telescope will drop to -30 degrees C. If the distance between the mirrors is exactly 80 cm in the lab, how much would the length of the zerodur spacer change in space? The properties of the material zerodur can be found in the table. Coefficient of thermal expansion is 2x10^-8 K^-1 and specific heat is 3347.20 J/kg/K
