Water at a gauge pressure of P = 4.8 atm at street level flows into an office building at a speed of 0.98m/sthrough a pipe 5.6 cm in diameter. The pipe tapers down to 2.0 cm in diameter by the top floor, 16 m above, where the faucet has been left open. Assume no branch pipes and ignore viscosity.
A) Calculate the flow velocity.
B) Calculate the gauge pressure in the pipe on the top floor.
A uniform electric field of magnitude 380 N/C pointing in the positive x-direction acts on an electron, which is initially at rest. The electron has moved 2.60 cm. (a) What is the work done by the field on the electron? J (b) What is the change in..
