A grandfather clock is controlled by a swinging brass pendulum that is 1.5 m long at a temperature of 28°C. (a) What is the length of the pendulum rod when the temperature drops to 0.0°C? (Give your answer to at least four significant figures.)

A grandfather clock is controlled by a swinging brass pendulum that is 1.6 m long at a temperature of 26°C. (a) What is the length of the pendulum rod when the temperature drops to 0.0C? (Give your answer to at least four significant figures.) mm (b) If a pendulum's period is given by T = 2nV L/g, where L is its length, does the change in length of the rod cause the clock to run fast or slow? O fast O slow O neither

A long steel I-beam used in bridge construction has a length of 20.0 m. The beam may be exposed to temperatures as low as -17°C in the winter and as high as 37°C in the summer. What is the difference in length of the beam between these two temperature extremes? (Give the absolute value of the difference. Enter your answer in mm.) X

The volume of a bubble that starts at the bottom of a lake at 4.55°C increases by a factor of 8.00 as it rises to the surface where the temperature is 18.15°C and the air pressure is 0.965 atm. Assuming that the density of the lake water is 1.00 g/cm3, determine the depth of the lake. (Please type answer no write by hend).

A grandfather clock is controlled by a swinging brass pendulum that is 1.6 m long at a temperature of 28°C. (a) What is the length of the pendulum rod when the temperature drops to 0.0°C? (Give your answer to at least four significant figures.) 85120 X Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully. mm (b) If a pendulum's period is given by T = 2√/L/g, where L is its length, does the change in length of the rod cause the clock to run fast or slow? O fast O slow O neither ✔

In everyday experience, the measures of temperature most often used are Fahrenheit F and Celsius C. Recall that the relationship between them is given by the following formula. F = 1.8C + 32 Physicists and chemists often use the Kelvin temperature scale. You can get kelvins K from degrees Celsius by using the following formula. K = C + 273.15 (a) Calculate that value.K(25) = (b) Find a formula expressing the temperature C in degrees Celsius as a function of the temperature K in kelvins. C = (c) Find a formula expressing the temperature F in degrees Fahrenheit as a function of the temperature K in kelvins. F =  (d) What is the temperature in degrees Fahrenheit of an object that is 272 kelvins?
