Ans: 1.0x10^-4
A glass flask whose volume is exactly 1000 cm3 at 0 degree C is filled level full of mercury at this temperature. When flask and mercury are heated to 100 degree C, 15.2 cm3 of mercury overflow. If the cubical coefficient of expansion of mercury is 0.000182 per centigrade degree, compute the linear coefficient of expansion of the glass. A simple pendulum is constructed of a fine steel wire supporting a small brass ball. Its period is measured at a point on the earth's surface where g = 980.00 cm/sec2, and where the temperature is 27 degree C The pendulum is then taken to an elevation of 8 km above the earth's surface. At what temperature will its period equal its original period? (Approximate finite changes by differentials.) A clock whose pendulum makes one vibration in 2 sec is correct at25 degree C. The pendulum shaft is made of steel and its moment of inertia may be neglected compared with that of the bob. What is the fractional change in length of the shaft when it is cooled to 15 degree C? How many seconds per day will the clock gain or lose at 15 degree C? A watch with a balance wheel a balance wheel in the form of an annular brass ring (neglect the effect of the spokes) keeps correct time at a temperature of 30 degree C. By how many seconds per day will it be in error at a temperature of 15 degree C? will it gain or lose? A slender steel rod oscillates as a physical pendulum about a horizontal axis through one end. The change in its period when the temp, is decreased to 0 degreeExplanation / Answer
