A laser shines on a pair of vertical slits. The horizontal distance 1 between the laser and the ruler is 12.3 m. The distance 2 between the laser and the slits is 0.511 m. The distance is 0.410 mm.

To a of 4 x hz is 1. 0. mm nm nm

What does the law of conservation of mass state?

Engines for propeller-driven aircraft are limited in their maximum rotational speed by the fact that the tip speed of the propeller must not approach the speed of sound in air (mach i). taking 6 ft as a typical diameter for a propeller of a light airplane and 1100 fils as the speed of sound, find the upper limit on the rpm (revolutions per minute) of the propeller shaft.
