The longest and shortests wavelengths of the Lyman series of singly ionized Helium

The atoms in a gas can be treated as classical particles if their De Broglie wavelength is much smaller than the aveage separation between the particles d. consider monatomic helium gas (mHec^2 = 3727. molar mass = 4g/mol) at 1 atmosphere of pressure and...

Part 1 Fg = m1m2g/d^2 force of gravity = (mass 1)(mass 2)(gravitational constant)/distance^2 Fg =(1170kg)(5.98 x 10^24kg)(g)/(220km + 6.38 x10^6) I don't remember what the exact value for g (gravitational constant) is, but you can probably get that from y...

DIVIDE 34 3/8 BY 3 1/8 MULTIPLY 34 * 8 TO GET 272, ADD 3 TO GET 275/8 THEN MULTIPLY 3*8 TO GET 24 AND ADD 1 TO GET 25 NOW DIVIDE 275/8 BY 25/8 YOU GET 11 DRESSES

Use trigonometry to figure out the displacement in the y direction (1.2 m) * (cos 37) = displacement in the y direction Displacement in x direction is not a concern here since we are talking about the gravitational force the gives you delta y then use you...

put the center (the small hole) of the straight edge on the end of the base (so that the end of the base lines up with the hole. The other side of the angle you're measuring should line up with the curved part of the device the number that correspond to t...

Work = (F)(displacement) 11.3 * 5.7 m = work in x direction there is no acceleration, so we use to 11.3 N value * displacement 5.7m in the x direction no displacement in the y direction, so no work in that direction
