A tank of helium gas used to inflate toy balloons is at a pressureof 15.5x108 Pa and a temjperature of 293K. The tank'svolume is 0.020 m3. How large a balloon would it fill at1.00 atmoshpere and 323K?
Tube A, in a 20°C room, is observed to support standingwaves at frequencies of 48 Hz, 60 Hz and 72 Hz, but not at anyfrequencies in between (but possibly at higher and lower frequencies). Meanwhile tube B, which is the same length, supports standi..
Two identical blocks of mass m are connected by a cord of length l that runs over a massless frictionless pulley, as shown below. One mass sits on a frictionless horizontal table. Now suppose that the string has a total mass M, which is distributed u..
On Apollo Moon missions, the lunar module would blast off from the Moon's surface and dock with the command module in lunar orbit. Find the impact speed of the lunar module
A 357-g object is attached to a spring and executes simple harmonic motion with a period of 0.220 s. If the total energy of the system is 4.79 J, find the following. (a) the maximum speed of the object m/s (b) the force constant of the spring N/m (c)..
A 12.0-g bullet is fired horizontally into a 100-g wooden block that is initially at rest on a frictionless horizontal surface, what was the speed of the bullet at impact with the block
A neutron star has a mass of 1030 kg and a radius of 5 kilometers. A body is droped from a height of 20cm above the surface. Determine the speed of the body when it hits the surface
A 1.65 block is attached to a spring with spring constant 17. While the block is sitting at rest, a student hits it with the hammer and almost instantaneously gives it a speed of 59.
Interactive LearningWare 26.2 offers a review of the concepts that play roles in this problem. What is the height of the final image
What is the electric potential at the surface of a gold atom’s nucleus, which is assumed to be spherical? The radius of a gold nucleus is 6.6*10^-15 meters and the atomic number of gold is 79.
If the maximum kinetic energy given to the electrons in aCompton scattering experiment is 10kev, what is the wavelength of the incident X-rays
A satellite with a mass of 750 kg is in orbit around the earth. It is initially located at the altitude (measured from the earth's surface) of 2.12 x 106 m. It is then moved into a new orbit, with an altitude of 4.25 x 10^6 m (again, measured from..
Two blocks are resting on a horizontal surface. The blocks are in contact with each other and a horizontal force of300 N is pushing on the left block which is m1 ontom2 which is on the right. What is the acceleration of the masses
