Question

If an astronaut travels 900,000 km from earth and fires a bullet pointing towards earth by standing opposite to the sun ? (the bullets speed is 300miles per hour)a)find the distance between the man and the earth b)find the distance travelled by the astronaut in space when he fires bullet​

Answer 1

The resolving power of an instrument is given by the formula, R.P=1.22×dλDHere, d is aperture of the instruments, D is distance of satellite from the earth. Here eye is the optical instruments.R.P=5×10−31.22×500×10−9×400×1000          =1.22×10−310−2×4=1.22×40=50m

Hope you got your answer!!♥️✅✌
