The formula for gravitational potential energy is Ep= mgh. Lets convert 594 km into m: 594 x 1,000 = 594,000 m. So we do: Ep= (1,800kg)(9.8N/kg)(594,000m) = (17,640N)(594,000) = 10,478,160,000 J.

Explanation:
The problem is based on the concept of Doppler's effect of em wave .
Expression for apparent frequency can be given as follows
n = N x (V - v ) / ( V + v )
n is apparent frequency , N is real frequency , V is velocity of light and v is velocity of cloud.
n = 6 x 10⁹ ( 3 x 10⁸ - 8.52 ) / ( 3 x 10⁸ + 8.52 )
= 6 x 10⁹ ( 3 x 10⁸ ) ( 3 x 10⁸ + 8.52 )⁻¹
= 6 x 10⁹ ( 3 x 10⁸ ) ( 3 x 10⁸)⁻¹ ( 1 + 8.52/3 x 10⁸ )⁻¹
= 6 x 10⁹ ( 1 - 8.52/3 x 10⁸ )
= 6 x 10⁹ - 6 x 10⁹x 8.52/ (3 x 10⁸ )
= 6 x 10⁹ 1 - 170 .
So change in frequency = 170 approx.
