Roughly where is the magnet when the light bulb is the brightest? (the brightness of the light bulb correlates with how much the needle of the voltmeter gets deflected away from the middle.) now, let’s look at a situation with changing flux. starting from the far left of the screen, move the magnet to the right so it goes through the middle of the two loops coil at a constant speed and out to the right of the coil. roughly where is the magnet when the light bulb is the brightest? (the brightness of the light bulb correlates with how much the needle of the voltmeter gets deflected away from the middle.) the brightness of the light bulb is the same, regardless of the location of the magnet (as long as it is moving). the light bulb is brightest when the middle of the magnet is in the middle of the coil. the light bulb does not shine since the magnet is moving at a constant speed. the light bulb is brightest when either end of the magnet is in the middle of the coil

Cathy is pedaling down a steep hill on her bicycle and wants to be able to coast up the next hill, which is 25 meters high, without pedaling. cathy and her bicycle have a mass of 75 kg. assuming her bicycle is 100% efficient, what would her speed have to be?

In the future, people will only enjoy one sport: electrodisc. in this sport, you gain points when you cause metallic discs hovering on a field to exchange charge. you are an electrodisc player playing the popular four disc variant. the disks have charges of qa = −8.0 µc, qb = −2.0 µc, qc = +5.0 µc, and qd = +12.0 µc. (1) you bring two disks together and then separate them. you measure the resulting charge of these two disks and find that it is +5.0 µc per disk. which two disks did you bring together? (a) a and b (b) a and c (c)a and d (d)b and c(e) b and d (f) c and d. (2) you bring three disks together and then separate them. you measure the resulting charge of these three disks and find that it is +3.0 µc per disk. which three disks did you bring together? a, b, and c (a) a, b, and d (c) a, c, and d (d) b, c, and d. (3) given the resulting charge of each disk measured in (b) is +3.0 µc, how many electrons would you need to add to a disk of this charge to electrically neutralize it? electrons

Object a has a length of 3 cm, a width of 2 cm, and a height of 4 cm. object b is dropped into a graduated cylinder. it displaces 19 ml of water. the volume of object a is: a: greater than the volume of object b b: less than the volume of object b c: equal to the volume of object b
