Consider neon, a noble gas whose molecules consist of single atoms of atomic mass 0.02 kg/mol. Avogadro's number is 6.02 × 1023 mol-1, and Boltzmann's constant is 1.38×10-23 J/K.
What is the average kinetic energy of a neon atom when the gas is at a temperatureof 400 K?
A parallel-plate air capacitor is made by using two plates 19 cm square, spaced 3.5 mm apart. It is connected to a 3-V battery. What is the electric field between the plates
trumpet creates a sound intensity level of 1.23 x 10^2 dB at a distance of 0.80 m. What is the sound intensity of a trumpet
A girl of m1=60 kg springs from a trampoline with an initial upward velocity of Vi=8.0 m/s. what is the speed of the girl immediately before she grabs the box
A common problem inside orbiting space stations is monitoring astronauts weight, or better said mass. What is the mass of the astronaut
At one point in a pipeline, the water's speed is 3 m/s and the gauge pressure is 4.00×10^4 Pa. Find the gauge pressure at a second point in the line 11 m lower than the first if the pipe diameter at the second point is twice that at the first.
A helicopter is ascending perpendicularly with a speed of 5.42 m/s. At a height of 146 m above the Earth, a package is dropped from a window. How much time does it take for package to reach the ground.
the coyote accidentally runs off the edge of a cliff and plummets to the ground 30.0 m below. Illustrate what force does the ground exert on the coyote as he makes a coyote-shaped dent 0.420 m deep in the ground?
A flywheel comprises a uniform circular disk with a moment of inertia of 5.70×101 Kg m2. What energy (in Joules) must this force dissipate to stop the wheel
o particles with charges +9e and -9e are initially very far apart (effectively an infinite distance apart). which is the change in the electric potential energy
To determine the muzzle velocity of a bullet fired from a rifle, you shoot the 3.71-g bullet into a 2.45-kg wooden block. find the velocity of the bullet on leaving the gun's barrel
A parallel-plate capacitor has square plates that are 6.00cm on each side and 4.20mm apart. If the potential difference between the plates is 78.0V , how much electrical energy is stored in the capacitor
A gymnast with mass m1 = 41 kg is on a balance beam that sits on (but is not attached to) two supports. The beam has a mass m2 = 108 kg and length L = 5 m. Each support is 1/3 of the way from each end. at least the gymnast stands at the left end of..
