A narrow glass tube, open at one end, closed at the other, is 40cm long. The tube resonates at its 2nd allowed resonant frequency due to a sound source moving away from the tube at 40m/s .The air temperature is -4 CO.
1. Find the wavelength of the resonant wave.
2. Determine the frequency of the moving sound source
An unstrained horizontal spring has a length of 0.34 m and a spring constant of 200 N/m. Two small charged objects are attached to this spring, one at each end, determine the possible algebraic signs
A factory worker pushes a 30kg crate a distance of 4.50 meters along a level floor at constant velocity by pushing it downward at an angle of 30degrees below the horizontal. The coefficient of kinetic friction between the crate and the floor is 0...
When a 5.5 cm long pencil is arranged perpendicular to a convex mirror's optical axis at a distance of 29 cm from the mirror, its image is 2.8 cm tall. (a) What is the mirror's focal length? (b) How tall is the pencil's image if the pencil is move..
