Predict/Calculate A pendulum consists of a large weight suspended by a steel wire that is 0.9500 m long. (a) If the temperature increases, does the period of the pendulum increase, decrease, or stay the same? Explain. (b) Calculate the change in length of the pendulum if the temperature increase is 150.0C°. (c) Calculate the period of the pendulum before and after the temperature increase. (Assume that the coefficient of linear expansion for the wire is 12.00 × 10−6 K−1, and that g = 9.810 m/s2 at the location of the pendulum.)

- Stars A and B have the same temperature, but star A has twice the radius of star B. (a) What is the ratio of star As power output to star Bs output due to electromagnetic radiation? The emissivity of both stars can be assumed to be 1. (b) Repeat the question if the stars have the same radius, but star A has twice the absolute temperature of star B. (c) Whats the ratio if star A has both twice the radius and twice the absolute temperature of star B?arrow_forwardA grandfather clock is controlled by a swinging brass pendulum that is 1.3 m long at a temperature of 20.0C. (a) What is the length of the pendulum rod when the temperature drops to 0.0C? (b) If a pendulums period is given by T=2L/g, where L is its length, does the change in length of the rod cause the clock to run fast or slow?arrow_forwardA grandfather clock is controlled by a swinging brass pendulum that is 1.3 m long at a temperature of 20.0C.

- Equal 0.400-kg masses of lead and tin at 60.0C are placed in 1.00 kg of water at 20.0C. (a) What is the equilibrium temperature of the system? (b) If an alloy is half lead and half tin by mass, what specific heat would you anticipate for the alloy? (c) How many atoms of tin NSn, are in 0.400 kg of tin, and how many atoms of lead NPb are in 0.400 kg of lead? (d) Divide the number NSn of tin atoms by the number NPb of lead atoms and compare this ratio with the specific heat of tin divided by the specific beat of lead. What conclusion can be drawn?arrow_forwardAt our distance from the Sun, the intensity of solar radiation is 1 370 W/m2. The temperature of the Earth is affected by the greenhouse effect of the atmosphere. This phenomenon describes the effect of absorption of infrared light emitted by the surface so as to make the surface temperature of the Earth higher than if it were airless. For comparison, consider a spherical object of radius r with no atmosphere at the same distance from the Sun as the Earth. Assume its emissivity is the same for all kinds of electromagnetic waves and its temperature is uniform over its surface. (a) Explain why the projected area over which it absorbs sunlight is r2 and the surface area over which it radiates is 4r2. (b) Compute its steady-state temperature. Is it chilly?arrow_forwardUnreasonable Results A meteorite 1.20 cm in diameter is so hot immediately after penetrating the atmosphere that it radiates 20.0 kW of power. (a) What is its temperature, if the surroundings are at 20.0C and it has an emissivity of 0.800? (b) What is unreasonable about this result? (c) Which premise or assumption is responsible?arrow_forward
- The distance between telephone poles is 30.50 m in a neighborhood where the temperature ranges from 35C to 40C. If you hang a copper cable between two adjacent poles on a day when the temperature is 22.30C, what is the minimum length of the copper cable you must use for the cable to remain connected to the poles all year? Assume the cable is straight, and ignore the effect of gravity on the cable. Consider to have four significant figures and report your answer to four significant figures.arrow_forwardA 1.00-km steel railroad rail is fastened securely at both ends when the temperature is 20.0C. As the temperature increases, the rail buckles, taking the shape of an arc of a vertical circle. Find the height h of the center of the rail when the temperature is 25.0C. (You will need to solve a transcendental equation.)arrow_forwardTwo metal bars are made of invar and a third bar is made of aluminum. At 0C, each of the three bars is drilled with two holes 40.0 cm apart. Pins are put through the holes to assemble the bars into an equilateral triangle as in Figure P18.31. (a) First ignore the expansion of the invar. Find the angle between the invar bars as a function of Celsius temperature. (b) Is your answer accurate for negative as well as positive temperatures? (c) Is it accurate for 0C? (d) Solve the problem again, including the expansion of the invar. Aluminum melts at 660C and invar at 1 427C. Assume the tabulated expansion coefficients are constant. What are (e) the greatest and (f) the smallest attainable angles between the invar bars? Figure P18.31arrow_forward
- 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 = 134 cm long (Fig. P10.51). 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 18.0C to 46.5C.
