A 460-Hz tuning fork causes resonance in the tube depicted in the figure below when the length L of the air column above the water is 18.3 and 55.8 cm
Find the speed of sound in air.
What is the end correction to adjust for the fact that the antinode does not occur exactly at the open end of the tube?
Find out the magnitude of the force exerted by the right pillar while a 90.0 diver stands at the far end of the board.
The mass then travels vertically and it takes 1.10 s for the mass to reach the top of its trajectory. Determine the spring constant, in N/m. (Use g=9.81 m/s2). Assume that the time required for the spring to reach its full extension is negligible.
As a result of the friction between their surfaces, after a while, both disks spin at the similar angular speed. Determine the work done by the frictional torque.
Find distances between the lens and the film
How long does it take the crate to hit the ground. suppose that the plane continues to fly with the same velocity.
You hold a spherical salad bowl 90 cm in front of your face with the bottom of the bowl facing you. The salad bowl is made of polished metal with a 35 cm radius of curvature. What is the image (your face's image) distance along the central axis fr..
An airplane starting from airport A flies 304 km east, then 364 km at 35.5° west of north, and then 150 km north to arrive at last at airport B.
An 52.0 N box of clothes is pulled 6.7 m up a 30.0° ramp by a force of 107 N that points along the ramp. If the coefficient of kinetic friction between the box and the ramp is 0.22, compute the change in the box's kinetic energy.
On the floor1.5 m in front of the mirror is a small table, 0.75 mhigh. Illustrate what is the minimum height the mirror must have foryou to be able to see the top of the table in themirror?
In 0.181s, through a distance of 8.05 m, a test pilot's speed decreases from 88.9m/s to 0m/s. If the pilot's mass is 70 kg, how much work is done against his body.
