The headlights on a certain car are gauged to be 1 m apart. The diameter of the pupil in a human eye is 2.5 mm. What is the furthest distance at which a human eye could obviously see the headlights as two separate lights? Use a wavelength of 644 nm/wave.

Think only the bernoulli effect : An airplane with a mass of 2.0*10 6 kg. Has the air flow past the lower surface of the wings at 75 m/s. If the wings have a surface area of 1200m 2, how fast should the air flow over the upper surface of the wing if the plane is to stay in the air? T..

What is the ratio of the radii : A proton and an electron have the same kinetic energy and travel in parallel paths as they enter a region of constant magnetic field. They each begin to move in circular paths. What is the ratio of the radii?

White light is incident from air onto a triangular prism : White light is incident from air onto a triangular prism at a 45 degree angle by respect to the normal. It refracts at the prism then again at the air as it exits the prism. If the prism has an index of refraction of 1.49 for red light and 1.52 for v..
