A student rolls a 3 kilogram ball down the same ramp used in Setup 2. The speed of the ball after 2 seconds was 4 meters per second. The student concludes that the kinetic energy of the 3 kilogram ball is identical to the 1 kilogram ball after it has rolled down the ramp for 2 seconds.

Explain whether the student's conclusion is correct or incorrect. Use evidence from the investigation to support your answer.

Which statement best compares the two waves?

• Wave 1 has a higher frequency because it has a longer wavelength than wave 2.

• Wave 1 has a higher frequency because it has a higher amplitude than wave 2.

• Wave 2 has more energy because it has a higher amplitude than wave 1.

• Wave 2 has more energy because it has a higher frequency than wave 1.

A scientist hiking in a desert observes a cliff. The scientist makes a drawing of the layers of rock in the cliff and the types of fossils observed in the layers. Based on observations, the scientist determines layers 3 and 5 were formed from cooled lava. The scientist's drawing is shown above.

Identify the oldest layer in the rock cliff and explain your reasoning for the layer chosen.
