Q. A flute is designed to play middle C (262 Hz) as the fundamental frequency when all the holes are covered. The length of the flute is 0.655 m. Assume the air temperature is 20°C. How far from the end of the flute should the hole be that must be uncovered to play B above middle C (494 Hz)?
Q. Two freight cars, each with a mass of 2.4 multiplied by 105 kg, collide and stick together. One was initially moving at 3.4 m/s and the other was at rest. What is their final speed?
Sunlight is used in a double-slit interference experiment. The fourth-order maximum for the wavelength of 470 nm occurs at an angle of θ = 90°. Thus, it is on the verge of being eliminated from the pattern since θ cannot exceed 90°.
What is the advantage of the new crumple zone design in new car's today when they are in a car crash, explain answer from a physics standpoint?
A toy cork gun contains a spring whose spring constant is 10.02 N/m. The spring is compressed 5.0 cm and then used to propel a 6.00 g cork. The cork, however, sticks to the spring for 1 cm beyond its unstretched length before separation occurs. The m..

Two automobiles, each of mass 900 kg, are moving at the same speed, 15 m/s, when they have an inelastic collision.(a) In what direction and at what velocity does the wreckage move if one car was driving north and one south? (b) In what direction a..
Blocks with masses of 4.0, 8.0, and 9.0 are lined up in a row on a frictionless table. All three are pushed forward by a 16 force applied to the 4.0 block. How much force does the 8.0 block exert on the 8.0 block.
What is magnitude of the greatest force
W hat is balls initial speed
Heather and Jerry are standing on a bridge 56 above a river. Heather throws a rock straight down with a speed of 15. Jerry, at accurately the same instant of time, throws a rock straight up with the equal speed. Overlook air resistance.
