Astudent is given 2 small, identical ice cubes and places the ice cubes on blocks of two unknown materials. the ice cube on block #1 melts in 37 seconds. the ice cube on block #2 melts in 24 seconds. based on this information, what should the student deduce about the unknown material of the blocks? question 2 options: block #1 is a better conductor because it caused the ice to melt more slowly than the ice on block #2 block #1 is a better insulator because it caused the ice to melt more rapidly than the ice on block #2 block #2 is a better conductor because it caused the ice to melt more rapidly than the ice on block #1 block #2 is a better insulator because it caused the ice to melt more rapidly than the ice on block #1

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)
