- Question 16 2.9 Three Pulleys 2.9a A thin, light rope is draped over three frictionless pulleys arranged around the origin as shown. Each pulley is a solid disk of radius r=2cm and is equidistant from the origin. 5kg mass is attached to one side and a 7kg mass to the other. Before the masses are released and in motion, what is the total angular momentum in kgm2/s around the origin? Question 17 2.9b What fraction of the angular momentum is in the pulleys?arrow_forwardAt what temperature would water boil if the outside pressure was only 19,900 Pa in degrees Celsius?arrow_forwardWhich of these properties of a sound wave is associated with the pitch of the sound that we hear? amplitudefrequency intensity levelintensityarrow_forward
- A wave travels upward in a medium (vertical wave velocity). What is the direction of particle oscillation for the following? (a) a longitudinal wave parallel to the direction of propagationperpendicular to the direction of propagationarrow_forwardThe faster a molecule is moving in the upper atmosphere, the more likely it is to escape Earth's gravity. Given this fact, and your knowledge of rms speed, which of the following molecules can escape most easily from Earth's atmosphere if they are all at the same temperature?arrow_forwardThe temperature in one part of a flame is 2,100 K. What is the rms velocity of the carbon dioxide molecules at this temperature? Give your answer as the number of meters per second. mass of 1 mole of CO2 = 44.0 grams 1 mole contains 6.02 x 1023 molecules the Boltzmann constant k = 1.38 x 10-23 J/Karrow_forward
