Describe two different forces air can exert on an object. Which has more momentum, a 9,000 kg semi truck that is stationary, or a 300 kg motorcycle traveling 20 meters per second? Which has a greater inertia? Explain.
Suppose you are paddling in a canoe on a lake. Use one of Newton’s laws of motion to explain how your paddling moves the canoe. Describe that law, and explain how it applies.
Which of Newton’s laws of motion explains why it takes more force to push a cart loaded with books than the same cart when it is empty? Describe that law, and explain how it applies.
Suppose you run a mile around an oval-shaped track. Describe how you would experience acceleration at the start of your run and also at the end of your run. Could you experience acceleration in the middle of the run without changing your speed? Explain.
You are sitting in a moving train watching the scenery pass by. At some point, you pass a boy sitting on his porch watching your train go by. You are sitting still in the train, and so is the boy on his porch, even as you watch each other recede into the distance. Describe how your frame of reference and the boy’s affect how you perceive each other’s apparent motion.

d concave shape of wave rock

explanation:

the concave shape of wave rock is a very good evidence that supports the evolution of earth due to chemical weathering. if we talk about structure of   wave rock, studies have estimated that it is around 2.7 billion years old. it also serves as the foundation of evidence that it was the place where australian continent began to form.

how the structure of wave rock was created?

studies suggest that structure of wave rock was created when the surrounded area was started to weather due to which deposition of material started on the part of land which now contains wave rock.

the structure of wave rock is considered to be one of the best-known landforms in australia. at the height of around 15 cm, there can be found flared slopes which formulate the margins of hyden rock. it is now assumed by geologists that wave rock was created by subsurface water-induced weathering and not by glaciers, waves or wind.

due to deposition of material over the period of long time, the wave rock became tougher and tougher due to weathering from surrounding terrain. this makes it a physical evidence that supports   the evolution of earth due to chemical weathering.

hope it !

x would be the most and the least would be y because there are more fruit   and seeds than flock z has insects
