1. ### What is an inverse meter?

Hi, I'm doing some astronomy work and one problem involves using Rydberg's constant. However, it is inverse meters and I'm confused. Does that mean that it is 1/109737361.6 m? Thanks.
2. ### Pv=nrt and PV diagram

Homework Statement One mole of an ideal gas at an inital tempreature of 300K and pressure of 4 atm is carried through the following reversible cycle: a) It expands isothermally until its volume is doubled. b) It is compressed to its original volume at constant temperature. c) It is...
3. ### Mechanical Energy into Thermal

Homework Statement Students are designing an experiment to demonstrate the conversion of mechanical energy into thermal energy. They have designed the apparatus shown in the figure above. (To see the image, visit http://www.cs.utexas.edu/users/mfkb/Halo/CPL/Physics1998APexam.pdf [Broken] and...
4. ### Energy Level Diagram

Homework Statement A monatomic gas is illuminated with visible light of wavelength 400nm. The gas is observed to absorb some of the light and subsequently emit visible light of both 400nm and 600nm. The initial state is -5.0 eV and the ionized atom (continuous energy levels) is 0 eV. a) Draw...
5. ### Underwater Pressure sunken ocean liner

Homework Statement While exploring a sunken ocean liner, the principal research found the absolute pressure on the robot observation submarine at the level of the ship to be 413 atmospheres. The density of the surrounding saltwater was 1025kg/m^3. Calculate the gauge pressure on the sunken...
6. ### Sphere rolling down a ramp linear acceleration

Homework Statement "A solid sphere of radius R and mass M is initially at rest at the top of a ramp. The lowest point of the sphere is a vertical h above the base of the ramp. It is released and rolls without slipping down the ramp. Determine the linear acceleration while the sphere is...
7. ### Conservation of Energy/Angular Momentum

Homework Statement Hi. The problem is "A wooden block of mass m slides with an initial speed of vi up a straight incline that makes an angle of theta with the horizontal. If the incline is rough with a coefficient of kinetic friction uk, determine the maximum height it rises in terms of h...
