As more and more bulbs are connected in series to a flashlight battery, what happens to the brightness of each bulb? assuming that heating inside the battery is negligible, what happens to the brightness of each bulb when more and more bulbs are connected in parallel? (#100)
a. power dissipated will be inversely proportional to net resistance of series combination of bulbs. net resistance of series combination of bulbs will be equal to the sum of resistance of individual bulbs. thus, net resistance of all the bulbs will be large.
b. brightness of each bulb depends upon power dissipated in each bulb. since, only small amount of power is dissipated in each bulb, brightness of the bulbs will decrease as more bulbs are added.
c. when bulbs are connected across the battery in parallel, voltage across each bulb will be the same.
d. the brightness of each bulb will be the same when bulbs are connected in parallel (provided resistance of each bulb is the same).

Arunner is jogging at a steady 3.6 km/hr. when the runner is 2.9 km from the finish line, a bird begins flying from the runner to the finish line at 14.4 km/hr (4 times as fast as the runner). when the bird reaches the finish line, it turns around and flies back to the runner. even though the bird is a dodo, we will assume that it occupies only one point in space, i.e., a zero-length bird. how far does the bird travel? (b) after this first encounter, the bird then turns around and flies from the runner back to the finish line, turns around again and flies back to the runner. the bird repeats the back and forth trips until the runner reaches the finish line. how far does the bird travel from the beginning? (i.e. include the distance traveled to the first encounter)
