Answer 2

Answer:

FREQUENCY OF RADIO SIGNAL:- 5000MHz

FREQUENCY OF ECHO:- 100kHz

SPEED OF LIGHT :- C ~ 3*10^8

LET RELATIVE VELOCITY :- v

A.T.Q

$\frac{100}{5000000} = 2\frac{v}{c}$

$\frac{3 \times {10}^{8} }{5 \times {10}^{4} \times 2 } = v$

$v = 3 \times {10}^{3} m {s}^{ - 1}$

Hope it Helps
