Air that occupies 0.19 cubic meters at 1.03e+05 Pa gauge pressure is expanded isothermally to atmospheric pressure and then cooled at constant pressure until it reaches its initial volume. Compute the work done by the air.
In order to manufacture these coffee tables, the company would need to incur $525,000 in fixed costs for new equipment. Calculate the break-even point of the coffee tables in units sold.
Two loudspeakers placed 6.00 m apart are driven in phase by an audio oscillator having a frequency range from 1908 Hz to 2471 Hz, At what frequency of the oscillator does the sound reaching point P interfere constructively
A pump, submerged at the bottom of a well that is 34 m deep, is used to pump water uphill to the house that is 50 m above the top of the well, as shown above. All pressures are gauge pressures. Avoid the effects of friction, turbulence, and viscosity..
A 5g lead bullet travelling at 370-m/s is stopped by a large tree. If half the kinetic energy of the bullet is transformed into internal energy and remains with the bullet whilst the other half is transmitted to the tree, what is the increase in t..
Using and Atwood machine with masses m1 and m2, at first with m1 a distance 2h above m2, what is the speed of either mass they pass each other? Make use of energy to solve (hint they cross halfway between the starting positions of the two masses).
Draft Hypothesis and Design
The minimum stopping distance for a car traveling at a speed of 30 {m/s} is 60 {m}, including the distance traveled during the driver's reaction time of 0.50 {s}.What is the least stopping distance for the same car traveling at a speed of 41 {m/s}..
The radius of curvature of the curved side of a plano-convex lens made of glass (n=1.64) is 33cm
A 78-kg person in a moving car stops during a car collision in a distance of 0.78m, Determine the speed of the person before the air bag opens up
The magnetic field over a certain range is given by B= Bxi + Byj where Bx= 6T and By= 4T. What is the j component of the force
Throughout a hard sneeze, your eyes may shut for 0.41 s. If you are driving a car at 98 km/h during such a sneeze, how far does the car move during that time.
A stream of water strikes a stationary turbine blade horizontally. The incident stream has a velocity of +16m/s whilst the exit has a velocity of -16m/s. mass of water per second that strikes the blade is 30kg/s.find the magnitude of average force ex..
