Q. A bat emits a sound whose frequency is 91.20 kHz. The speed of sound in air at 20 degrees Celcius is 343m/s. However the air temperature is 38.8 degrees Celcius, so the speed of sound is not 343m/s. imagine that air behaves like an ideal gas, and finds wavelength of the sound.
Q. Coherent light with wavelength 593 passes through two very narrow slits, and the interference pattern is observed on a screen a distance of 3 from the slits. The first-order bright fringe is a distance of 4.84 from the center of the central bright fringe. For what wavelength of light will first-order dark fringe be observed at this same point on the screen?
A 0.150 kg ball is going around in a vertical circle of radius R = 0.300 m at constant speed v. The ball is attached to a mass less ideal string which is attached to a fixed pivot point. If the tension F in the string is greater than 125 N, the st..
You found the distance that you will cover at the same time as braking. You can utilize the expected amount of time for braking to check your answer for distance.

Two speakers, 6.00 m apart, are driven by the same audio oscillator so that each one produces a sound consisting of two distinct frequencies, 1000 Hz and 1360 Hz. The speed of sound in the room is 350 m/s.
A car moving at 10 m/s crashes into a barrier and stops in 0.50s. There is a 20kg child in the car. Suppose that the child's velocity is changed by the same amount as the cars in the same time period.
A concave mirror is of hemisphjerical shape with radius 40cm. A thin layer of unknown transparent liquid is poured into mirror. The mirror liquid forms a real image and another real image is formed by the mirror alone.
Both teenagers pull with a force of 55 at an angle of 35 relative to the forward direction, that is the direction of motion. In addition, the snow exerts a retarding force on the sled that points opposite to the direction of motion, and has a magn..
