Consider a single magnetic monopole with unit magnetic "charge" traveling in a straight line down the x axis. an observer stationed at coordinate (0,0,1) on the z axis will observe a pulse of electric field as the monopole goes by. (a) plot the magnitude of the y component of this field as a function of time for each of the following choices of monopole velocity: b-0.6, b 0.8, β 09, β 0.99. (b) plot the x and z components of the electric field for the same set of velocities.

Aflask with vinegar in it has a mass of 160 grams. a balloon with baking soda in it has a mass of 40 grams. the balloon is attached to the flask to seal the opening and the vinegar and baking soda mixes. the balloon inflates to a large volume. what will the total mass of the balloon and flask be after the balloon inflates? explain. a) less than 200 grams because the solid baking soda disappears. b) 200 grams, because all the atoms remain in the balloon or flask. c) more than 200 grams because the size of the balloon is so much larger. d) less than 200 grams because gases such as the one in the balloon are lighter than solids and liquids.

On mars a rock falls an unknown vertical distance from a resting position and lands in a crater. if it takes the rock 2.5 seconds to fall, how high is the cliff the rock fell from? mars' surface gravity is 3.8 m/s2.
