Choose the best answer to etch of the following. Explain your reasoning.

What two pieces of information would you need in order to measure the masses of star in an eclipsing Binary System? (a)the time between Atlas and the average distance between the stars (b) the period of The Binary System and its distance from the Sun (c) the velocities of the stars and the Doppler Shifts of their absorption lines.

23. What is the velocity of a beam of electrons that goes undeflected when passing through perpendicular electric and magnetic fields of magnitude 8.8 X 103 V/m and 7.5 X 10-3 T. respectively? What is the radius of the electron orbit if the electric field is turned off?
10. A light bulb emits 25.00 W of power as visible light. What are the average electric and magnetic fields from the light at a distance of 2.0 m?
9. Some 1800 years ago Roman soldiers effectively used slings as deadly weapons. The length of these slings averaged about 81 cm and the lead shot that they used weighed about 30 grams. If in the wind up to a release, the shot rotated around the Roman slinger with a period of .15 seconds. Find the maximum acceleration of the shot before being released in m/s^2 and report it to two significant figures.
