Marine debris is any trash or litter that ends up in a marine environment. This harms wildlife through entanglement, ingestion, and disturbs the habitat of many species of animals. This becomes a global problem when it is a danger to human health. Nails, syringes, and glass can cause harm to people on the beach. On top of that, trash in the waterway increases the amount of chemicals destroying our water quality.

Answer:
Maximum speed of the car is 26.56 m/s.
Explanation:
Given that,
Mass of the car, m = 1200 kg
Radius of the curve, r = 90 m
The coefficient of friction between tires and the road is 0.8.
We need to find the maximum speed of the car. On the circular curve, the centripetal force is balanced by the force of friction. So,
So, the maximum speed of the car is 26.56 m/s.
Catastrophic events are sudden, natural or man-made, situations where change & destruction occur. All catastrophic events are the Earth's way of maintaining equilibrium during change.
Answer:
It is neither false nor true. When they collide some of one of the objects goes to the other object.
Explanation:
1) Time to get the highest point of it pathway>
Vf = Vo - g*t
Vf = 0 (condition of maximum height)
Vo = 5.33 m/s
g = 9.81 m/s
=> t = Vo / g = 5.33 m/s / 9.81 m/s = 0.543 s
2) Time to return from the highest point = time to get to the highest point = 0.543 s
Total time = 0.543s + 0.543 s = 1.086 s ≈ 1.09 s
Answer: 1.09 s
