A close coiled helical spring of round steel wire 10 mm diameter having 10 complete turns with a mean radius of 60 mm is subjected to an axial load of 200 N. Determine the deflection of the spring. C = 80 kN/mm2.
A speedboat moving at 38.0 m/s approaches a no-wake buoy marker 100 m ahead. What is the velocity of the boat when it reaches the buoy
What assumptions must be made? Explain all of your assumptions, state where you got the additional information you needed, show your calculations, and justify your work (give reasons why we should believe that you are correct).
A parallel plate capacitor is attached to a battery that supplies a constant voltage. What happens to the energy stored in the capacitor
Consider n moles of an ideal monatomic gas placed in a vertical cylinder. The top of the cylinder is closed by a piston of mass M and cross-section A. Initially the piston is fixed, and the gas has temperature T0 and volume V0.
An oscillator vibrating at 1220Hz produces a sound wave that travels through an ideal gas at 325 m/s when the gas temperature is 22.0 ?C. What should the gas temperature be to achieve this wavelength
At which wavelengths (or energies) will you observe lines in infrared absorption (a phonon absorbs a photon) and raman scattering spectra? The temperature is 300 k. raman scattering is excited with a cw Argon laser at 514.5 nm.
A 1.53 kg ball is attached to a ceiling by a 3.06 m longstring. The height of the room is 5.12 m. Theacceleration of gravity is 9.8 m/s2. What is the gravitational potential energy associated with theball relative to the ceiling? What is the gravita..
