Explain all answers clearly, with complete sentences and proper essay structure if needed. An asterisk (*) designates a quantitative problem, for which you should show all your work.
Adding Up Asteroids. It’s estimated that there are a million asteroids measuring 1 kilometer across or larger. If a million such asteroids were combined into one object, how big would it be? Compare your answer to the size of Earth. (Hint: Assume that each asteroid is a sphere with a radius of 0.km; the volume of a sphere is.)

- Assume that there are a million asteroids 1 kilometer across or larger in the asteroid belt. For both questions, assume that all the asteroids are perfectly spherical. I a. If a million asteroids 1-kilometer across were all combined into one spherical object, how big would it be across? b. How many 1-kilometer diameter asteroids would it take to make an object as large as the Earth?arrow_forwardRead the following items carefully. State your assumptions if any. Show your COMPLETE solution and BOX your final answers.

What is the gge of the obiect?arrow_forwardWrite a CR for the solved problem. A example of one is attached as well. The problem about the ROCK is the example CR. The problem you ARE writing a CR for is 5x^2-8x=3. Instructions below. For the CR's, claim you should answer the question of , do you get 2 real solutions, 1 real solution, or 2 complex solutions? For your reasoning you should explain how you know. Use the example attached to help you answer. hints: that plus minus sign means there are two answers. If the number under the square root is positive, you have two real solutions. If the number is negative you have two complex solutions. If the number is 0 under the square root you have 1 real number solution.arrow_forwardShow your complete, clear and detailed solution. Please explain also how did you get your answer.
