Afan blade is initially at rest. it then undergoes angular acceleration for 10s , at a constant rate of 10rads2 . which of the following equations gives the correct value for the angular velocity after 10s ?

What you see with your eyes is a form of energy. a. light b. heat c. chemical d. electrical

Awave has a wavelength of 7 mm and a frequency of 19 hertz. what is its speed?

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.
