The diagram below represents a series of rock layers from a single location. Each different type of shape shown in the layers represents a fossil of a different species. Suppose each symbol is related to a particular species in the following ways: A green square represents a species of carnivorous dinosaur. A yellow triangle represents a species of fern tree. A blue star represents a species of conifer tree. A purple circle represents a species of early amphibian. A red starburst represents a species of beetle. Judging from the diagram, which statement is true? A. The carnivorous dinosaur species lived at the same time as the conifer tree species. B. The fern tree species lived at the same time as the beetle species. C. The carnivorous dinosaur species lived after the early amphibian species. D. The fern tree species lived before the early amphibian species.

The picture shows a fishing technique called trawling. how might trawling affect marine biodiversity

Consider the motion of the balloon and its air contents in terms of momentum. in step 1 above, the total momentum of the balloon and its contents was zero. recall that momentum = mv. both the balloon and the air inside it had a velocity of zero and therefore the total momentum was zero. now think about what happened when the air escaped from the balloon. a certain mass of air accelerated in one direction. in order to keep the total momentum of the system zero, the balloon itself (which has mass) had to accelerate in the opposite direction. use this scenario to you explain why the soda can rotates when the water squirts out of the escape holes. what was your hypothesis concerning the water-filled can? according to your data, do you think your hypothesis was correct? (be sure to refer to your data when answering this question.) summarize any difficulties or problems you had in performing the experiment that might have affected the results. describe how you might change the procedure to avoid these problems. give at least one more example of newton's third law in everyday life.
