The nearest star to the earth is Proxima Centuri. It is 4x1016 meters from New York City. The distance to Perth on the exact other side of the globe is about 11,000 miles. Given that 1 mi = 1609 m, how many orders of magnitude

further from New York is Proxima Centuri compared to Perth?

Note: An order of magnitude is an estimate of size based on how many multiples of ten something is bigger or smaller compared

to something else. If I have $1 and you have $200 we can say you have 2 orders of magnitude more money than me because it is

two factors of 10 larger. If you had $1,000,000 it would be 6 orders of magnitude more. For this question we don't want you to say

exactly how much farther this star is, but approximate in terms of orders of magnitude.

(04.05 hc) analyze the given diagram of the carbon cycle below. an image of carbon cycle is shown. the sun, a cloud, two trees, one on the left and the other on the right, an animal, lake, and a factory are shown in the image. an arrow is shown from the sun towards the left tree marked a. the sun is marked b. there is an arrow from the air above the clouds, marked c, towards the left tree. an arrow from a location close to the ground marked d points towards dead organisms, which is a label under the animal. an arrow marked e points from the right tree straight up to the clouds. an arrow marked f points from the animal straight up to the clouds. an arrow marked g points from the factory towards the air above the clouds, c. there is an arrow pointing from the air to the lake labeled carbonates in water, an arrow pointing down from dead organisms to fossils and fossil fuels, and an arrow from fossils to the factory. part 1: which compound does c represent? part 2: name a process that could release this compound into the air. part 3: explain how the elements that form it are conserved during the carbon cycle. use complete sentences to explain your answer.
