A U-tube is made up of two capillaries of bores 1.2 m and 2.4 mm respectively. The Tube is held vertical and partially filled with liquid of surface tension 0.06 N/m and zero contact angle. If the estimated difference level in the two menisci is 1.5 mm, determine the mass density of the liquid

Athermometer is removed from a room where the temperature is 70° f and is taken outside, where the air temperature is 10° f. after one-half minute the thermometer reads 60° f. what is the reading of the thermometer at t = 1 min? (round your answer to two decimal places.) ° f how long will it take for the thermometer to reach 30° f? (round your answer to two decimal places.)

If a simple machine reduces the strength of a force, what must be increased?

Why is rain likely when warm, moisture-laden air meets cold air? a) the lighter warm air will rise and cool down, causing condensation and rain. b) the cold air moves faster and pushes the warm air away, causing condensation and rain. c) the moisture in the warm air condenses on contact with the cold air, causing rain to fall. d) the cold air mixes with the warm air, reducing its temperature causing moisture to condense.
