Studying fossils allowed researchers to learn about organisms that lived long ago. The fossils provide as evolutionary evidence that shows how organisms in our present time have evolved over time and which common ancestors they are tied to. Fossils also provide information about climate change depending on the region and location they are found in. Fossils also date back to millenias ago, so fossils dated very far back in the past can help researchers infer that life had existed even farther than what they might have discovered. And finally, by studying fossils, you can determine how the organism may have died.

A man pushes a lawn mower with a force of 200N across 50N meters of his lawn. How much work did the man perform?

krok68 [10]

Work is equal to force times distance or W = Fn x d

In this situation, you would use the following equation:
W= 200N x 50N

W= 10,000N

The man performed 10,000N of work.
