Suppose that you titrate a 3 g sample of orange juice and it turns out to contain only 95.5mg of vitamin C. Further, it took 32.45mL of DCP solution to reach the end point of the titration.
You want to photograph a circular diffraction pattern whose central maximum has a diameter of 1.2 cm. You have a helium-neon laser (landa= 633 nm) and a 0.13 mm-diameter pinhole. How far behind the pinhole should you place the viewing screen?
A helium-neon laser beam has a wavelength in air of 633 nm . It takes 1.38 ns for the light to travel through 30 cm of an unknown liquid. What is the wavelength of the laser beam in the liquid?
Methane enters a heat exchanger at a volumetric flow rate of 120.0 m3/min, at a pressure of 1.013 bar and temperature of 5.0°C. At these conditions, the specific enthalpy of methane is -45.181 kJ/kg.
If 15.0 m3/min of steam at 450.0°C and 10.0 bar enters a turbine and leaves as saturated steam at 9.25 bar, what is the volumetric flow rate of steam leaving the turbine? If the turbine operates adiabatically, what is the work output?
The lowest tone to resonate in an open pipe of length L is 200 Hz. Which one of the following frequencies will not resonate in the same pipe?
