Q. An experimenter wishes to generate in air sound wave that has a dislacement amplitude of 5.50*10 m. The pressure amplitude is to be limited to 0,840 N/m. What is the minimum wavelength the sound wave can have?
Q. A sailor strikes the side of his ship just below the surface of the sea. He hears the echo of the wave reflected from the ocean floor directly below 9.0 s later. How deep is the ocean at this point? (Note: Use the bulk modulus method to determine the speed of sound in this fluid, rather than using a tabluated value.)
Find the distance from the mirror to the point where the reflected rays meet.
Create the magnitude of the net gravitational force on moon
An ocean liner leaves New York City and travels 18.0° north of east for 232 km. How far east and how far north has it gone? In other words, what are the magnitudes of components of the ship's displacement vector in the following directions.
What will be its length and height at rest
On an airplane's takeoff, the combined action of the air around the engines and wings of an airplane exerts an 8020-N force on the plane, focussed upward at the angle of 55.0° above the horizontal. The plane rises with constant velocity in the vertic..
An average force of 201 N is exerted to draw the string back 1.3 m. unless otherwise directed, imagine that air resistance is negligible. Illustrate energy bar graphs to solve the difficulty .
Suppose a train engineer is climbing a vertical ladder at a speed of 0.2m/s while the train is slowly coasting east at 0.70 m/s. Find out the vector of the engineer relative to the ground in rectangular notation.
2.0 kg ball moving with a speed of 3.0 m/s hits, elastically, an identical stationary ball as shown. If the first ball moves away with angle 30° to the original path,
A 203 rad dose of radiation is administered to a patient in an effort to combat a cancerous growth. Suppose that all of the energy deposited is absorbed by the growth.
The potential at the center of a uniformly charged ring is 44kV, and 15.0 cm along the ring axis potential is 30kV. Find the ring's radius and its total charge.
What is average kinetic energy of each helium atom
A cat runs along a straight line (the x-axis) from point A to point B to point C. The distance between points A and C is 5.00 m, distance between points B and C is 10.0 m, and the positive direction of x axis points to the right. The time to run f..
