Chapter 8.2, Problem 2aT
Galvanometer
Obtain a device like the one shown below.It contains a coil made of many loops of wire and a magnet suspended so that it is free to swing. A pointer has been attached to the magnet so that a small swing of the magnet will result in a large deflection of the pointer. When there is no current through the coil, the magnet is horizontal and the pointer is vertical.
Predict the deflection of the pointer (if any) when the switch is closed. Explain the reasoning you used to make your prediction.
Connect the circuit and observe the deflection of the pointer. If your observation is in conflict with your prediction, discuss your reasoning with a tutorial instructor.
The device above is called a galvanometer and can be used to detect current. If the scale on the galvanometer has been calibrated to measure amperes, the device is called an ammeter.

- 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?
