Question 16 For this question, as long as you answer it, you will receive a mark; however, we Not yet ask that you answer honestly, as we will be using the results to improve the answered course. Your response will in no way affect your grade in the course. Thank Marked out of you for your cooperation. 1.00 In eClass, there is a section entitled "Learning Objectives, Content Outlines and Flag question Practice Problems," where weekly PDFs are provided, which contain (i) weekly learning objectives, (ii) outlines of content that is taught each week and (iii) additional problems. Please select the answer that best describes how you use these PDFs in learning the course material. Select one: O a. I don't know how to find them. O b. I use them as the course lecture notes. O c. They overlap with the lecture notes provided by my course professor, so I only use the additional problems at the end. O d. I use them as a study guide to supplement the lecture notes provided by my course professor, and I find them helpful. O e. I have seen them on eClass but don't know how to use them. O f. I prefer not to answer. O g. I don't know what these are. O h. I use them as a study guide to supplement the lecture notes provided by my course professor, but they are not that helpful.Question 17 Not yet answered Marked out of 1.00 V" Elag question You wish to check your luggage for a flight. However, the scale at the airport is broken. You found a spring that obeys Hooke's Law hanging off the wall. Assume the spring is weightless. You hang a jug of 2 kilogram of water from the spring and observe that the spring stretches beyond its natural length by 5 centimetre. If you hang a 10 kg luggage from the spring, how far does it stretch beyond its natural length? Assume distance is measured in metres. Use a calculator to find a numerical approximation of your final answer to 2 decimal places. For example, if your final answer is &, then you should enter 3.14 in the box below. In tests and the final exam, you will NOT need to approximate your final answer numerically. Question 18 Not yet answered Marked out of 1.00 V" Elag guestion A cable hangs off the roof of a 20-metre building. The cable weights 10 kilograms and is 3 metres long. You lift the cable by pulling from its top end. How much work does it take to lift the entire cable to the top of the building? Assume work is measured in newton-metres (N - m). Use a calculator to find a numerical approximation of your final answer to 2 decimal places. For example, if your final answer is &, then you should enter 3.14 in the box below. In tests and the final exam, you will NOT need to approximate your final answer numerically. Question 19 Not yet answered Marked out of 1.00 V" Elag question A 5 kg weight is attached to the bottom of a 10-metre long rope, which dangles out a window. Assume the weight does not touch the ground. The rope alone has a mass of 1 kg. How much work does it take to pull the entire rope through the window, together with the weight? Assume work is measured in newton-metres (N - m). Use a calculator to find a numerical approximation of your final answer to 2 decimal places. For example, if your final answer is &, then you should enter 3.14 in the box below. In tests and the final exam, you will NOT need to approximate your final answer numerically. Back Question 20 Not yet answered Marked out of 1.00 V" Elag question A leaky bucket picks up 20 litres of water from a well but drips out 1 litre every second from the bottom. If the bucket was lifted 5 metres from the surface of the water at a constant speed of 2 m/s, how much work is done? Assume the bucket has negligible mass. Assume work is measured in newton-metres (N - m). Use a calculator to find a numerical approximation of your final answer to 2 decimal places. For example, if your final answer is &, then you should enter 3.14 in the box below. In tests and the final exam, you will NOT need to approximate your final answer numerically
