1. Determine the minimum throat diameter required for a nozzle to pass 0.250 lbm/s of air from a stagnation state of 100. psia at 70.0°F.
2. Atmospheric air (14.7 psia, 70.0°F) leaks into an initially evacuated 2.00 ft3 tank through a tiny hole whose area is 1.00 × 10-6 ft2 . Determine the time required for the pressure in the tank to rise to 0.528 times the atmospheric pressure, if the air inside the tank is maintained at 70.0°F.
You are at the controls of a particle accelerator, sending a beam of 2.70×107 protons (mass ) at a gas target of an unknown element. Your detector tells you that some protons bounce straight back after a collision with one of the nuclei of the unk..
The second-order dark fringe in a single-slit diffraction pattern is 1.40 mm from the center of the central maximum. calculate the wavelength of the incident light
2012 Nissan Maxima (1607 kg) can go from rest to 60.0 mph in 5.7 s. What is the percentage of its raw power
Suppose that a comet that was seen in 627 A.D. by Chinese astronomers was spotted again in year 1988. determine the semimajor axis of the comet's orbit
The average coefficient of volume expansion for carbon tetrachloride is 5.81 10^-4 (°C)?1. how much will spill over when the temperature rises
You need to decide the density of a ceramic statue. If you suspend it from a spring scale, the scale reads 28.4 N. If you then lower the statue into a tub of water, so that it is totally submerged, the scale reads 17.0 N. What is the density?
A hammer strikes one end of a thick steel rail of a length 8.50 m. A microphone located at the opposite end of the tail detects two pulses of sound, Find the separation in time between the arrivals of the two pulses
Two small, positively charged spheres have a combined charge of 5.43×10-5 C. If each sphere is repelled from the other with an electrostatic force of 1.00 N when the spheres are 2.07 m apart, what is the charge on the sphere with the smaller charge?
A cyclotron operates with a given magnetic field and at agiven frequency. If R denotes the radius of the final orbit, the final particle energy is proportional to 1/R. A cyclotron operates with a given magnetic field and at agiven frequency. If R ..
A 47.0g golf ball is driven from the tee with an initial speed of 52.0 m/s and rises to a height of 24.6 m. neglect air resistance and determine the kinetic energy of the ball at its highest point.
The equation of a transverse wave traveling in a rope is given by y=10sinx(0.01x-2.000. where y and x are expressed in centimeters and t in seconds. Find the amplitude, frequency, velocity and wavelength of the wave. Find the maximum transverse speed..
Imagine a sphere of radius R filled with negative charge of uniform charge density. The total charge is equivalent to the charge of two electrons. Now insert two protons into the sphere and assume that in spite of their presence, the negative charge ..
