Force between a hydrogen nucleus and an unknown nucleus.
A H nucleus & a nucleus of yet an unknown atom are stationary at 5.0x10^-10 m apart, Hydrogen atoms mass is mH = 1.7x10^-27kg with an electric charge of e = 1.6x10^-19 C. The Coulomb constant is Ke = 9.0x10^9 Nm^2 C^-2 and that the gravitational constant is G = 6.7x10^-11 N m^2 kg^-2. Is the force between the hydrogen and the ...continues

Cosmology- How far away is the galaxy in mega parsecs?
If a galaxy has a luminosity of 6.6x10^39 W and a brightness measured as 1.25x10^-11 W m^-2, How far away is the galaxy in mega parsecs? An absorption line of the element beryllium is observed in the spectrum of the galaxy above as lying 509.4 nm. What is the speed of the recession of the galaxy in km s^1 assuming that the sp ...continues
Astronomy - I know the value of one parsec in metres but how is it calculated?
(1) I know the value of one parsec in metres but how is it calculated? (2) Can you give a brief note on Hubble's Constant?
