This mathematical model describes the changes that occur in a sample of water as its temperature increases. based on this model, how do you expect the motion of the molecules in ice to compare with the motion of molecules in water vapor?

a. i expect the molecules in ice to move more quickly than the molecules in water vapor.
b. this model does not provide enough data to answer the question.
c. i expect the motion to be very similar.
d. i expect the molecules n water vapor to move more quickly than the molecules in ice.

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.)

Your starship, the aimless wanderer, lands on the mysterious planet mongo. as chief scientist-engineer, you make the following measurements: a 2.50-kg stone thrown upward from the ground at 14.0 m/s returns to the ground in 5.70 s ; the circumference of mongo at the equator is 2.20×10^5 km ; and there is no appreciable atmosphere on mongo. (a) the starship commander, captain confusion, asks for the following information: what is the mass of mongo? (b) if the aimless wanderer goes into a circular orbit 2.20×10^4 km above the surface of mongo, how many hours will it take the ship to complete one orbit? (c) an unmanned spacecraft is in a circular orbit around the moon, observing the lunar surface from an altitude of 44.0 km . to the dismay of scientists on earth, an electrical fault causes an on-board thruster to fire, decreasing the speed of the spacecraft by 23.0 m/s . if nothing is done to correct its orbit, with what speed (in km/h) will the spacecraft crash into the lunar surface?

Atoy airplane, flying in a horizontal, circularpath, completes 10. complete circles in 30.seconds. if the radius of the plane’s circular pathis 4.0 meters, the average speed of the airplane is(1) 0.13 m/s (3) 1.3 m/s(2) 0.84 m/s (4) 8.4 m/s
