A Foucault pendulum consists of a brass sphere with a diameter of 31.0 cmcm suspended from a steel cable 11.5 mm long (both measurements made at 20.0∘C∘C). Due to a design oversight, the swinging sphere clears the floor by a distance of only 3.00 mmmm when the temperature is 20.0∘C∘C. Part A At what temperature will the sphere begin to brush the floor?

A Foucault pendulum consists of a brass sphere with a diameter of 38.0 cmcm suspended from a steel cable 11.5 mm long (both measurements made at 20.0∘C∘C). Due to a design oversight, the swinging sphere clears the floor by a distance of only 3.00 mmmm when the temperature is 20.0∘C∘C. a). At what temperature will the sphere begin to brush the floor?
In a manufacturing facility, 5-cm-diameter brass balls (r = 8522 kg/m3 and cp = 0.385 kJ/kg · °C) initially at 120°C are quenched in a water bath at 50°C for a period of 2 min at a rate of 100 balls per minute. If the temperature of the balls after quenching is 74°C, determine the rate at which heat needs to be removed from the water in order to keep its temperature constant at 50°C.
Water enters a 2.5-cm-internal-diameter thin copper tube of a heat exchanger at 15°C at a rate of 0.3 kg/s, and is heated by steam condensing outside at 120°C. If the average heat transfer coefficient is 800 W/m2·°C, determine the length of the tube required in order to heat the water to 115°C
Suppose due to a bad break of your femur, you require the insertion of a titanium rod to help the fracture heal. The coefficient of linear expansion for titanium is α = 8.60 × 10−6 K−1, and the length of the rod when it is in equilibrium with the leg bone and muscle at 37.0°C is 6.50 cm. How much shorter was the rod at room temperature (20.0°C)?
Carbon steel balls (r = 7833 kg/m3, k = 54 W/m·K, cp = 0.465 kJ/kg·°C, and a = 1.474 * 1026 m2/s) 8 mm in diameter are annealed by heating them first to 900°C in a furnace and then allowing them to cool slowly to 100°C in ambient air at 35°C. If the average heat transfer coefficient is 75 W/m2·K, determine how long the annealing process will take. If 2500 balls are to be annealed per hour, determine the total rate of heat transfer from the balls to the ambient air.
The north wall of an electrically heated home is 20 ft long, 10 ft high, and 1 ft thick, and is made of brick whose thermal conductivity is k = 0.42 Btu/h·ft·°F. On a certain winter night, the temperatures of the inner and the outer surfaces of the wall are measured to be at about 62°F and 25°F, respectively, for a period of 8 h. Determine (a) the rate of heat loss through the wall that night and (b) the cost of that heat loss to the home owner if the cost of electricity is $0.07/kWh.
A 425 g metallic object at 125.0 oC with a heat capacity of 0.386 J/(g·oC) is added to a calorimeter containing 250.0 mL of water with heat capacity of 4.184 J/(g·oC) at 25.0 oC. Assuming the calorimeter does not absorb heat, calculate the final temperature of the system in oC.
The outer diameter of a glass jar and the inner diameter of its iron lid are both 760 mmmm at room temperature (20.0 ∘C). What will be the size of the mismatch between the lid and the jar if the lid is briefly held under hot water until its temperature rises to 62.5 ∘C, without changing the temperature of the glass? Use the coefficient of linear expansion for iron α= 1.2×10^−5 K^−1. Express answer in millimeters.
A short brass cylinder (r = 8530 kg/m3, cp =0.389 kJ/kg·K, k = 110 W/m·K, and a 5 *.39 3 1025 m2/s) of diameter 8 cm and height 15 cm is initially at a uniform temperature of 150°C. The cylinder is now placed in atmospheric air at 20°C, where heat transfer takes place by convection with a heat transfer coefficient of 40 W/m2·K. Calculate (a) the center temperature of the cylinder; (b) the center temperature of the top surface of the cylinder; and (c) the total heat transfer from the cylinder 15 min after the start of the cooling.

The height of the Washington Monument is measured to be 170 m on a day when the temperature is 39.0°C. What will its height be in meters on a day when the temperature falls to −16.5°C? Although the monument is made of limestone, assume that its thermal coefficient of expansion is the same as marble's. (Assume the temperature of the entire monument changes from 39.0°C to −16.5°C. Enter your answer to at least five significant figures.) ____________________ m
Two 5-cm-diameter, 15-cm-long aluminum bars (k = 176 W/m·K) with ground surfaces are pressed against each other with a pressure of 20 atm. The bars are enclosed in an insulation sleeve and, thus, heat transfer from the lateral surfaces is negligible. If the top and bottom surfaces of the two-bar system are maintained at temperatures of 150°C and 20°C, respectively, determine (a) the rate of heat transfer along the cylinders under steady conditions and (b) the temperature drop at the interface.
