Assume it takes 7.00 minutes to fill a 30.0 gal gas tank. (a) calculate the rate at which the tank is filled in gallons per second. (b) determine the rate at which the tank is filled in cubic meters per second. (c) determine the time interval, in hours, required to fill a 1.00 m^3 volume at the same rate. ( 1 us gal = 231 in.^3)

Astring that is fixed at both ends has a length of 1.05 m. when the string vibrates at a frequency of 91.0 hz, a standing wave with five loops is formed. (a) what is the wavelength of the waves that travel on the string? (b) what is the speed of the waves? (c) what is the fundamental frequency of the string?

Agas contained within a piston-cylinder assembly undergoes three processes in series: process 12: compression with pv= constant from 1 bar and 1 liter to 4 bar. process 23: constant pressure expansion to 1 liter. process 31: constant volume calculate the pressure and volume at each state, and sketch the processes on a p-vdiagram labeled with pressure and volume values at each numbered stat

10 newton object is placed 3 meters from the fulcrum. at what distance on the other side would you need to place a 15 newton object to balance the lever? show your work!
