A particle with charge 7.80 mC is moving with velocity v S = 13.80 * 103 m>s2ne. The magnetic force on the particle is measured to be F S = +17.60 * 10-3 N2nd 15.20 * 10-3 N2k n. (a) Calculate all the components of the magnetic field you can from this information. (b) Are there components of the magnetic field that are not determined by the measurement of the force? Explain. (c) Calculate the scalar product B S ~ F S . What is the angle between B S and F S ?

Astronomy 101 TextBook Notes Chapter 1 Universe - the totality of all space, time matter, and energy Astronomy - the study of the universe Light Year - the distance traveled by light in a year, at a speed of 300,000 kilometers per second = 6 trillion miles Theory - the framework of ideas and assumptions used to explain some set of observations and make predictions about the real world Theoretical Model - constructed to figure out a theory. Makes further predictions about a particular object’s properties or how it will behave or change under new circumstances Scientific Method - investigation, combining thinking and doing, theory, and experiment - must be testable - must continuously be tested - should be elegant - should be simple - Occam’s Razor
