Answer:

Paleozoic era

Explanation:

The first major extinction in Earth's history occurred two to five million years ago, two deadly climaxes over hundreds of thousands of years. Most creatures lived in the seas at this time, so many of the marine creatures of that time, such as trilobites, brachiopods, and graptolites, were destroyed. During this third deadliest extinction, 5 to 5 percent of all species have been extinct.

This is data from a visible satellite image. What types of weather conditions are associated with the image?
masya89 [10]
Hurricanes (also known as typhoons or cyclones, depending on the location on Earth where they form) are often associated with extremely powerful winds and torrential rains. I am not sure about the pressure, but the only option here that mentions both strong winds and a lot of rain is A. low pressure, high winds, high precipitation, so I'd say that is the correct answer.

irinina [24]

When faced with a complex engineering problem, the best strategy usually involves( A ) Breaking the problem down into smaller problems and solving them individually.

Explanation:

Th first step of solving a complex problem involves problem identification-it means what exactly is the problem then we try to determine the possible sub-groups in which the problem can be further divided  and then numbering the sub groups.

The process of sub-grouping means that we are sub dividing the problems and then working upon the problem that needs the attention first and then according solving the other sub categories of the problem.

This method helps in breaking the complex problem into a series of small task that can be easily solved in a sequential manner .Thus the complexity of the problem gets reduced when it is divided into a number of small problems.

Serga [27]
The work done is 137 joules.

Lifting opposes the acceleration of gravity, which is 9.8 m/sec/sec.

20 x 0.7 x 9.8 = 137 J (kg-m2/sec2)
