- 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
