According to a rule-of-thumb, every 5 seconds, between a lightning flash and the following thunder gives the distance to the flash in miles. assuming that the flash of light arrives in essentially no time at all, estimate the speed of sound in m/s from this rule.

If the ama of the inclined plane below is 2, calculate the ima and efficiency. ima = efficiency =

Question 1 (5 pts): what is the maximum distance for which you can you resolve the two individual headlights of an on-coming truck as two separate lights rather than one if the headlights are separated by 2.00 m and your eye has a diameter of 1.00 centimeter? assume a wavelength of 500 nm.
