Calculate the ratio rtube/rcap for the setup in investigation 1, where rtube is the resistance of the tube connection the reservoir and the capillary and rcap is the resistance of the capillary. what conclusion can you draw from this? length of the tube = 79.0 cmdiameter of the tube = 0.727 cmlength of the capillary = 10.0 cm

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)
