• ### Two stars 14 light-years away are barely resolved by a 110 cm (mirror diameter) telescope.?

How far apart are the stars? Assume λ=550nm and that the resolution is limited by diffraction. i did 1.22*lamda in m/diameter in m got 6.1*10^-7 then multplied by 14 to get 8.54*10^-6 light year this in meters being 8.1*10^16 m. I still got this wrong. where did i mess up?

Find the magnitude of its momentum p = 4.41×1011 kg⋅m/s Compare your answer to Part A with what you would have found had you used the classical expression for momentum . How do the relativistic and the classical momenta compare? The relativistic momentum is greater than the classical momentum. The relativistic momentum is equal to the classical momentum. The relativistic momentum is less than the classical momentum. What is the total energy E of the meteorite? What would the energy of the meteorite be if it were at rest? What is the relativistic kinetic energy K of the meteorite when it travels at 0.700 c ? Express your answer in joules.
