A machinist wishes to insert a silver rod with a diameter of 9 mm into a hole with a diameter of 8.992 mm. By how much would the machinist have to lower the temperature (in °C) of the rod to make it fit the hole?  °C

At 20 °C, an aluminum ring has an inner diameter of 2.99 cm and an outer diameter of 4.00 cm. The ring needs to fit over a stainless steel rod that has a diameter of 3.00 cm at 20 °C. Assume that the ring and rod are situated such that they both need to be heated by the same flame. To what temperature in °C must the rod and ring be heated so that the ring just barely slips over the rod? Use coefficients of linear expansion: αal = 2.3 × 10-5(°C)-¹ and αst = 1.7 × 10-5(°C)−¹. A. 441 °C B. 527 °C C. 563 °C D. 583 °C E. 627 °C

A brass rod 5 m long and 0.01 m in diameter increases in length by 0.05 m when its temperature is increased by 500 °C. A similar brass rod of length 10 m has a diameter of 0.02 m. By how much will this rod's diameter increase if its temperature is increased by 1000 °C? A) 32 deg C B 42 deg C (C) 52 deg C D) 62 deg C

A steel plug has a diameter of 9.000 cm at 30  °C. At what temperature will it fit exactlyinto a hole of constant diameter of 8.998 cm? ⍺ = 11 x 10^-6/°C

A 0.0500-kg ice cube at −30.0 °C is placed in 0.400 kg of 35.0-°C water in a very well-insulated container. What is the final temperature?

On a roller coaster ride the total mass of a cart - with two passengers included - is 268 kg. Peak K is at 43.2 m above the ground and peak L is at 26.0 m. At location K the speed of the cart is 17.2 m/s, and at location L it is 12.5 m/s. (The wheel mechanism on roller coaster carts always keeps the carts safely on the rail.) K How much mechanical energy is lost due to friction between the two peaks? Submit Answer Tries 0/10

A vertical glass tube of length L = 1.4m is half filled with a liquid at 23.8 °C. How much will the height of the liquid column change when the tube is heated to 32.8 °C? Take aglass = 1.21x 10-5/K and Bliquid=4.02× 10-5/K. Number Units
