Briefly, but informatively, discuss about the sources of groundwater contamination. Compute each of the following: a. ( 7 5 ) b. ( 8 2 ) c. ( 3 3 ) d. ( 4 0 ) e. ( 9 8 ) Michelson-Morley Experiment (a) Why is Michelson Morley experiment important? (b) What were the findings of Michelson-Morley experiment? (c) What is the principle of Michelson interferometer? . What does it mean for automation to substitute for labor? What does it mean for automation to compliment labor? 2. Would you rather a work in an industry where automation and new machines compliment labor, or an industry where automation substitutes for labor? Explain your answer. 3. Suppose that the development of new package sorting robots allows Amazon, Walmart, Fedex, UPS and DHL to completely eliminate all human package sorting jobs. Describe a scenario where the number of jobs available in the entire economy (all industries) would nevertheless increase as a result of the employment of these new robots. In other words, describe a scenario where automation leads to more total jobs in the economy. 4. Suppose the income elasticity of demand for personal fitness trainers and yoga instructors is very large and positive. If automation were to make the energy sector of the economy (oil, natural gas, etc.) more productive and profitable, what would you expect to happen to total employment in the personal fitness and yoga instructor sectors of the economy? 5. Describe how recent automation has changed the qualities of jobs available. For this question, focus on pages 9-14 of the article. 6. Give an example of a job that will likely disappear (for humans) due to automation. What is it about the job you chose which makes new machines a good substitute, for human labor? spherical capacitor is made of a solid conducting sphere of radius 30 cm, and a conducting spherical shell of inner radius 60 cm and outer radius 70 cm, concentric with the sphere. The capacitor is charged by a 50 V battery (not shown). Please answer each of the following questions. a) What is the capacitance in pF ? b) What is the charge on the inner sphere in nC ? c) What is the energy stored in nJ ? he drawing shows four point charges. The value of q is 2.0C, and the distance d is 0.91 m. Find the total potential at the location P. ssume that the potential of a point charge is zero at infinity. Number Units A high jumper leaves the ground with a resultant velocity of 4.0 m/s at an angle of 35 from the right horizontal from an initial vertical center of mass position of 1.37m. Draw a picture of the projectile motion to help define phases. 1.What was her vertical velocity at takeoff? 2.What was the horizontal position of her center of mass at the top of the jump? 3.What was the vertical position of her center of mass at the top of the jump? 1. A beam of light travels from a vacuum (c=3.0010 8m/s) into a substance at an angle of 45,with a frequency of 6.0010 14Hz and a speed of 2.1310 8m/s. The index of refraction of the substance is a) 0.707 c) 1.50 b) 1.41 d) indeterminable, but 1 2. You observe diffraction in a ripple tank (Figure 1). To increase the diffraction of the waves in the region beyond the barrier, you consider the following adjustments: a) 0.707 c) 1.50 b) 1.41 d) indeterminable, but 1 The best adjustments or combinations of adjustments is a) (i) only d) (i) and (iii) only b) (ii) only e) (i), (ii) and (iii) c) (iii) only of the following are accurate statements regarding random assignment except __________. group of answer choices A spherical, concave, shaving mirror has a radius of curvature of 32.1 cm. Part A What is the magnification of a person's face when it is 12.1 cm to the left of the vertex of the mirror? Where is the image? Express your answer in centimeters. 3. Use Convolution theorem, find \[ L^{-1}\left\{\frac{s^{2}}{\left(s^{2}+w^{2}\right)^{2}}\right\} \] when the consumer price index cpi is calculated using the prices of a market basket of prducts what kind of products are includes in the market basket Which of the following statements about law enforcement and the mentally ill is true:Group of answer choicesThis answer is falseThe mentally ill are arrested 20% less than those without a mental illnessMost police go through extensive training on dealing with the mentally illThe mentally ill are more likely to give false confessions Question 23 List two explicit costs for you to go to Whistler for a weekend, and three implicit costs. Consider the labour discipline model applied to two countries, a high-wage country and a low-wage country. Assume that the high-wage country has a higher unemployment benefit. Consider a firm producing the same product in both countries. Which of the following statements is correct? The workers' best response curve in the high-wage country is to the left of that in the lowage country. The efficiency wage offered in the low-wage country is higher than that in the high-wage country. Firms would make lower profits in the low-wage country than in the high-wage country. The threat of outsourcing from the high-wage country to the low-wage country (that leaves workers in the high-wage country unemployed workers' best response curve in the high-wage country. QUESTION 3 [12] Water is pumped through a 60 m long pipe with a diameter of 0,3 m from a lower reservoir to a higher reservoir whose surface is 10 m above the lower one. The sum of the minor loss coefficients for the system is KL = 14,5. When the pump adds 40 kW to the water the flowrate is = 0,20 m/s. Draw a sketch to demonstrate the scenario and determine the pipe roughness. A mass of 6x10-9 kg carries a charge of 40 C and its velocity is 100 m/s which is perpendicular to magnetic field. The radius of the circular motion is 0.03 m. Calculate the magnitude of the magnetic field?
