Question
Chapter 1, Problem 42EAP
(a)
To determine
The sketch which shows both the Milky Way Galaxy and Andromeda Galaxy and the distance between them by using a scale such that 1 centimeter is equivalent to 100,000 light years.
(b)
To determine
To explain:
How the separation of the galaxies can be compared with separation of the stars and consequently explain the comparison of the likelihood of galactic collisions with the likelihood of stellar collisions.

- 13.87 ... Interplanetary Navigation. The most efficient way to send a spacecraft from the earth to another planet is by using a Hohmann transfer orbit (Fig. P13.87). If the orbits of the departure and destination planets are circular, the Hohmann transfer orbit is an elliptical orbit whose perihelion and aphelion are tangent to the orbits of the two planets. The rockets are fired briefly at the depar- ture planet to put the spacecraft into the transfer orbit; the spacecraft then coasts until it reaches the destination planet. The rockets are then fired again to put the spacecraft into the same orbit about the sun as the destination planet. (a) For a flight from earth to Mars, in what direction must the rockets be fired at the earth and at Mars: in the direction of motion, or opposite the direction of motion? What about for a flight from Mars to the earth? (b) How long does a one- way trip from the the earth to Mars take, between the firings of the rockets?
