A standing wave in a pipe with both ends open has a frequency of 680 Hz. The next higher harmonic has a frequency of 1020 Hz.
a) Determine the fundamental frequency.
b) How long is the pipe?
Find out the moment of inertia of the wheel. Initially the wheel rotates with an angular speed , causing the block to rise with a linear speed = 0.33 .
An 9.00 {rm kg} point mass and a 15{rm kg} point mass are held in place 50{rm cm} apart. A particle of mass m is released from a point between the two masses 19{rm cm} from the 9{rm kg} mass along line connecting the two fixed masses.
A 120g ball moving at 0.50 m/s in the + x direction is subject to a 0.25 N force in the - y direction for 2.5 s, Find the balls final speed
what is the translational rms speed of carbon dioxide molecules.
The solar wind is a thin, hot gas given off by the sun. Charged particles in this gas enter the magnetic field of the earth and can experience a magnetic force, calculate the radius of the circular path on which the particle would move if it were a..
A bullet of mass 0.0022 kg initially moving at 503 m/s embeds itself in a large fixed piece of wood and travels 0.71 m before coming to rest. Assume that the acceleration of the bullet is constant.
Purchase new automated equipment that will change the proportion between variable and fixed costs to 40% variable and 60% fixed. Determine the selling price per unit. Calculate the break-even point in dollars for 2011.
A jetliner can fly 5.32 hours on a full load of fuel. Without any wind it flies at the speed of 220 m/s. The plane is to make a round-trip by heading due west for a certain distance, turning around, and then heading due east for the return trip.
An aircraft performs a maneuver called an aileron roll. During this maneuver, the plane turns like a screw as it maintains a straight flight path, which is the acceleration of the wing tip
Points A, B, and C are at the corners of an equilateral triangle of side 5 m. Equal positive charges of 5 µC are at A and B, What is the potential at point C
