To Explain:Two things about a magnetic field that a field lines represent.
Explanation of Solution
Introduction:
A magnet is a material in which domains are aligned in one direction and so, it is able to attract other magnetic materials. A moving charged particle also generates magnetic field around it.
Magnetic field around a magnet is a region where magnet has an influence. The field lines are imaginary lines which represent the force field around the magnet. When a positive test charge is placed in the force field, the direction of motion the test charge indicates the direction of the magnetic field. Magnetic field lines emerge from north pole and enter into south pole.

- 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? (c) To reach Mars from the…arrow_forwardNo chatgpt pls will upvotearrow_forwarda cubic foot of argon at 20 degrees celsius is isentropically compressed from 1 atm to 425 KPa.
