A gas at 23°C and atmospheric pressure fills a cylinder. The gas is transferred to a new cylinder by four times the volume, after which the pressure is a quarter the original pressure. What is the new temperature of the gas?
A block of mass 0.540 kg is pushed against the horizontal spring of negligible mass until the spring is compressed a distance x. The force constant of the spring is 450 N/m.
A pressure measure at the top of an oil well 18,000 ft deep registers 2,000 psig. The bottom 4,000-ft portion of the well is filled with oil (\rho = 43.68 lbm/ft3). The remainder of the well is filled with natural gas (T= 60 °F, compressibility facto..
Consider the circuit shown in the figure below. (Assume R1 = 12.0Ω, R2 = 2.20Ω, andV = 6.00 V.) Calculate the equivalent resistance of the R1 and 5.00Ω resistors connected in parallel.
A double-slit experiment is set up using red light (l = 714 nm). A first order bright fringe is seen at a given location on a screen. What wavelength of visible light (between 380 nm and 750 nm) would generate a dark fringe at the identical locati..
