A 0.14 meter string clamped at both ends under a tension of 16 N has a fundamental frequency of 135 Hz.
What is the wavelength of the fundamental mode of oscillation?
What is the frequency of the 3rd harmonic?
What is the mass density of the string?
How far from the end would you have to hold the string down to create the frequency of 400 Hz?
how high does it rise above the point of free.
Three resistors, R1 = 30? , R2 = 71? , and R3=R, are connected in parallel with a 12Vbattery, Find the value of resistance R and currenrt through each resistor
The system is released from rest, and the string moves without slipping over pulley. If the larger mass is traveling at a velocity of 2.25 m/s when it has dropped 1m, how much mechanical energy was lost due to friction in the pulley's axle.
In the bohr model of the hydrogen atom, an electron is the 6th excited state moves at a speed of 60km/s in a circular path having a radius of 2mm.
The power supply for a pulsed nitrogen laser has a 0.0050-mF capacitor with a maximum voltage rating of 30 kV, calculate the power of the laser pulse
An ideal gas at 20 C consists of 2.2 X 10^{22} atoms. 4.3 J of thermal energy are removed from the gas. What the new temperature in C.
