Steel Brass 0.010 m 0.030 m 5.0 um An electronic device has been poorly designed so that two bolts attached to different parts of the device almost touch each other in its interior, as in the Figure below. The steel and brass bolts are at different electric potentials and if they touch, a short circuit will develop, damaging the device. If the initial gap between the ends of the bolts is 5 umat 25° C, at what temperature will the bolts touch? The coefficients of linear thermal expansion for brass and iron are 19 x 10 (°C)' and 11 x 10 (C) respectively. Select one: A. 32 C B. 26° C C. 48°C O D. 12 C

Review 8-64 (algorithmic) Question Help ▼ When boiling water, a hot plate takes an average of 8 minutes [min] and 35 seconds [s] to boil 110 milliliters [mL] of water. Assume the temperature in the lab is 71 degrees Fahrenheit ["F]. The hot plate is rated to provide 385 watts [W]. If we wish to boil 110 milliliters [mL] of acetone using this same hot plate, how long do we expect the process to take? Acetone has a boiling point of 56 degrees Celsius [c].
