Assume the car is moving at 72 km/hr when the brake pedal is applied. Assume that the radius of the wheel is 15 cm. What is the maximum power.
X rays diffract from a crystal in which the spacing between atomic planes is 0.188 nm. The second-order diffraction occurs at 59.0 degrees. What is the angle of the first-order diffraction?
If you want to find the latent heat of fusion, you take a cup with 0.755 kg of water at 30.00 C and drop 0.0850 kg of ice initially at 0.000 C and it all reaches an equilibrium temperature of 19.00 C,
Use the surface energy balance equation to calculate the latent heat flux given that the Bowen ratio is 0.6, the net incoming radiation is 50 J m-2 s-1
