An ideal monatomic gas is contained in a vessel of constant volume 0.340 m3. The initial temperature and pressure of the gas are 300 K and 5.00 atm, respectively. The goal of this problem is to find the temperature and pressure of the gas after 15.0 kJ of thermal energy is supplied to the gas.
(b) Find the specific heat of the gas.
_____ J/K
(c) What is the work done by the gas during this process?
_____ kJ
(d) Use the first law of thermodynamics to find the change in internal energy of the gas.
(e) Find the change in temperature of the gas.
_____ K
(f) Calculate the final temperature of the gas.
(g) Use the ideal gas expression to find the final pressure of the gas.
_____ atm
A computer disk is 8.0 in diameter. A reference dot on the edge of the disk is initially located at the disk accelerates steadily for 0.50, reaching 2000.
Illustrate what diameter has tip of the hour hand with 100 mil/hr tangential speed? If a 10 inch wide top is spinning at 300 RPM, what is the tangential speed at the widest part?
A ball is thrown in the air at an initial angle 35 degrees above the horizontal. It takes 4 seconds for the ball to hit the ground
A dynamite blast at a quarry launches a rock straight upward, and later it is rising at a rate of 15m/s. Assuming air resistance has no effect on the rock, calculate the total time the rock is in the air.
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.
In a certain region of space, the electric field, E, is constant in direction (say horizontally in the +x-direction), but its magnitude decreases.
An electron is released from rest at the negative plate of a parallel plate capacitor. The charge per unit area on each plate is = 2.6 x 10-7 C/m2, the plates are separated by a distance of 1.4 x 10-2 m. How fast is the electron moving just before..
moves through its horizontal position at (B) and up to (C) where it stops with 2 = 109.0o, and then falls back down. Friction at the pivot is negligible. Compute the speed of the CM at (B).
find the work done to move the particle from x = 0 to x = 10.0 m by graphically determining the area under the F versus x graph. (Do this on paper. Your instructor may ask you to turn in this graph.)
Use this technique to find formula for the intensity of a sound, in terms of sound level and the reference intensity. There will be a quantity involved in the calculations. When you enter your answer, leave off the unit.
