CONSTRUCTED RESPONSE OPTION #2 Scientists have studied climate change since the last 20 to 30 years. Given the graph of the CO2 concentration amount in Earth's atmosphere, provide an analysis for why Scientists warn about the dire need to switch from nonrenewable resources to renewable resources? You must provide 2 evidence in your analysis as a CER for full credit.

A33.1 g copper object is launched from a 1.5 m 30° steel incline positioned on the floor by being pulled up a string attached to a 50.0 g mass suspended vertically over a pulley. the object is projected towards a glass table where it lands when it is at the point along its trajectory with the lowest speed. it comes to a halt when it clears the opposite edge of the table. it then falls and lands on 9 physics texts each 5 cm thick that are stacked on the floor on the opposite side of the table. assume that the table does not have a ledge and the rectangular object experiences 0.05 n of air resistance as it falls towards the books. how far and how long did the object travel and how fast does it hit the books. assume that at the moment the copper object leaves the incline, the massless string and ideal pulley break off

What is the earliest point in the universe that we can observe? why can’t we see back further than this?

What is the final velocity of the initial velocity of 25 and -50?
