A particular organ pipe can resonate at 213 Hz, 355 Hz, and 497 Hz, but not at any other frequencies in between. What is the fundamental frequency of pipe.
A .228g wires are stretched between two points 77.20 cm apart. The tension in the wire is 618N. Find the frequency of the first harmonic. Reply in units of Hz.
Consider N atoms confined on a surface of area A at temperature T. The atoms form a two-dimensional (2D) gas of classical, non interacting particles.
An object, at the top of a very tall building, is released from rest and falls freely due to gravity. Neglect air resistance and calculate the distance covered by the object between times t1 = 5.57 s and t2 = 7.59 s after it is released.
A person with a mass of 103 kg is standing on a scale that reads weight in newtons inside of an elevator. If the elevator accelerates upward at 3.2 m/s2, what does the scale read.
The position of an object connected to a spring varies with time according to the expression x = (4.4 cm) sin(6.9?t). (a) Find the period of this motion. s (b) Find the frequency of the motion. Hz (c) Find the amplitude of the motion. cm (d) Find ..
In a charming 19th-century hotel, an old-style elevator is connected to a counterweight by a cable that passes over a rotating disk 3.50 m in diameter. The elevator is raised and lowered by turning the disk, and the cable does not slip on the rim ..
An adventurous archaeologist crosses between two rock cliffs. If the angle between the rope and the horizontal is = 11.8, find out the tension in the rope.
What is the resultant displacement when a dog runs 36 m North, and then changes direction to run 13.6 m West? answer sketching diagram and showing all calculation.
An electron moves at a speed of 480m/s perpendicular to the direction of the uniform magnetic field of 1 T. What is the radius of the electron's circular orbit in units of nanometers (1 m = 109 nm)
Determine the tension in each cable if boat has a mass of 490 kg and the angle of each cable is 50 degrees from the horizontal and the boat is being momentarily held at rest. Evaluate this to the tension when the boat is raised and held at rest so th..
Amazingly, at exact distance that you calculated in question 2a (73.5 meters), there was a trampoline! Thinking quickly, I orient myself appropriately and hit the trampoline.
