A4500-kg spaceship is in a circular orbit 190 km above the surface of earth. it needs to be moved into a higher circular orbit of 380 km to link up with the space station at that altitude. in this problem you can take the mass of the earth to be 5.97 × 1024 kg.

i am confused how to solve this problem, show how this answer is obtained.

Explanation:

Total energy of a satellite in an orbit , h height away

= -  GMm /2 ( R + h )

When h = 380 km

Total energy of a satellite =

=  - 13.25 x 10¹⁰ J

When h = 190 km

Total energy of a satellite =

=   - 13.63 x 10¹⁰ J

Diff

= 38 x 10⁸ J Energy will be required.

they are non-matter

explanation:

they are non-matter. basically, any type of energy or any abstract concept is an example of something that does not matter. other examples include dreams, magnetism, radio, and hate

distance = 150m

displ = root (50 ^2 + 100^2)

root(2500+10000)

root 125000
