Assume your eye has an aperture diameter of 3.00 mm at night when bright headlights are pointed at it. 1) at what distance can you see two headlights separated by 1.80 m as distinct? assume a wavelength of 550 nm, near the middle of the visible spectrum. (express your answer to two significant figures.)

Write short note on the following ; collision theory, rotation angle and angular velocity, centripetal acceleration, coriolis force, and newton's law of gravitation.

Wo audio speakers are placed on a vertical rail. speaker a is placed at head-level while speaker b is place at some variable height, \delta yδy, above speaker a. both speakers receive simultaneous input from a sine-wave generator so the speakers each produce a pure sinusoidal sound wave with a wavelength of 0.531 meters. calculate the lowest height that speaker b can be placed above speaker a to produce a minimum of sound heard by person standing \delta x = 7.86δx=7.86 meters directly in front of speaker a.
