Through an adiabatic process, the temperature of 3.62 {\rm mol} of a monatomic ideal gas drops from 480{\rm ^\circ C} to 240{\rm ^\circ C}.
A) Discover the work done by gas. B) Discover the heat the gas exchanges with its surroundings. C) Find the change in its internal energy.
Alpha particles (charge = +2e, mass = 6.68* 10^-27 kg) are accelerated in a cyclotron to a final orbit radius of 0.50 m. Determine the kinetic energy of an alpha particle in the final orbit
For my project I constructed a trebuche. A trebuche is an ancient device used for launching projectiles. It acheives this by harnessing potential energy and allowing this potential energy to convert into kenetic energy. This potential energy is st..
Using a grating with a spacing of 0.00046 cm, a line (which looks like red light) appears 27 cm from the central line on a screen. The screen is 1.9 m from the grating. What is the wavelength of the light?
A ball is thrown directly downward, with an initial speed of 6.25 m/s, from a height of 34.4 m. After what interval does the ball strike the ground
A rifle bullet of mass m = 0.03 kg traveling at vb = 240 m/s collides with and embeds itself in a pendulum of mass M = 2.88 kg, How high does the pendulum-bullet combination rise after the collision
A piano tuner stretches a steel piano wire with a tension of 964N . The wire is 0.400m long and has a mass of 3.60g. What is the frequency of its fundamental mode of vibration
a cargo barge is loaded in a saltwater harbor for a trip up a freshwater river. if the rectangular barge is 3.50 m by
A 2.0 kg block starts from rest on the positive x axis 3.0 m from the origin and thereafter has an acceleration given by a = 4.0 i -3.0 j in m/s2. At the end of 2.0 s its angular momentum about the origin is?
A light bulb emits light uniformly in all directions. The averageemitted power is 150.0 W. At a distance of 4 m from the bulb,determine (a) the average intensity of the light,(b) the rms value of the electric field, and(c) the peak value of the elect..
a 1.50-h inductor is connected in series with a 200nbspomega resistor through a 15.0-v dc power supply and a switch. if
Two particles with charges +6e and -2e are initially very far apart (effectively an infinite distance apart). They are then fixed at positions that are 4.92 x 10-10 m apart. What is EPEfinal - EPEinitial, which is the change in the electric potent..
A 1.2 m long steel rod with a diameter of 0.50cm hangs vertically from the ceiling. An auto engine weighing 4.7kN is hung from the rod. By how much does the rod stretch
