9-36 Repeat Prob. 9-34 using constant specific heats at room temperature. 9-34 An ideal Otto cycle has a compression ratio of 8. At the beginning of the compression process, air is at 95 kPa and 27C, and 750 kJ/kg of heat is transferred to air during the constant-volume heat-addition process. Taking into account the variation of specific heats with temperature, determine (a) pressure and temperature at the end of the heat-addition process, (b) the net work output, (c) the thermal efficiency, and (d) the mean effective pressure for the cycle. Answers: (a) the 3898 kPa, 1539 K, (b) 392 kJ/kg, (c) 52.3 percent, (d) 495 kPa a mass m = 3.95 kg is at the end of a horizontal spring on a frictionless horizontal surface. the mass is oscillating with an amplitude a = 7.5 cm and a frequency f = 0.45 hz.a. Write an equation for the spring constant k. b. Calculate the spring constant A. in Newtons per meter. c. Write an equation for the total mechanical energy. E, of the motion. Your expression should be in terms of the variables in the original problem statement. d. Calculate the total mechanical energy E, in joules discuss the significance of competitive intelligence gathering for organizations to succeed in a competitive field. Animals had begun to inhabit the land long before plant species evolved.TrueFalse Office Automation, Inc. must choose between two copiers the XX40 or the RH45.The XX40 costs $1,500 and will last for 3 years. The copier will require a real aftertax cost of $120 per year after all relevant expenses.The RH45 costs $2,300 and will lasts 5 years. The real aftertax cost for the RH45 will be $150 per year.All cash flows occur at the end of the year.The inflation rate is expected to be 5 % per year , and the nominal discount rate is 14%. Which copier should the company choose?What is the real discount rate? NPV? EAC? for each copierReal discount rateXX40:NPVEAC ?RH45:NPVEACThe two copiers have unequal lives, so they can only be compared byexpressing both on an equivalent annual basis which is what the EAC method does.We also must be sure to use the real interest rate since the cash flows are statedin real terms. Thus, you prefer thebecause it has the lower (less negative) annual cost. a spring has a spring constant k 14 8.75 n/m. if the spring is displaced 0.150 m from its equilibrium position, what is the force that the spring exerts? show your work. the value of net exports equals the value of a. national saving net capital outflow. b. national saving domestic investment. c. national saving. d. public saving. Some regulatory proteins interact with other proteins or DNA sequences to increase or decrease the rate of ____ 9.7/0.0268need help please Each of the following atoms is stripped of all orbital electrons and they are all placed in the same electric field. which ionized atom in the field is acted on by the strongest electrostatic force?a. 12 C6b. 12 N7c. 16 O8d. 19 O8e. 17 F9 why is geopolitics important to international economic transactions involving oil an interst sensitive life insurance policy owner may be ble to withdraw the poliicys cash value interest free the provision that allows this is called low tide inc. adopts a new technology purely out of social pressure. in this case, low tide inc. would be classified as part of the ________ group of adopters of new technology. a 2-kg rock is thrown upward with a force of 200 n at a location where the local gravitational acceleration is 9.79 m/s^2. what is the acceleration of the rock? Which statement below is FALSE? An analysis of how enforcing rent control in San Francisco affects the availability of rented accommodations in that city is principally a topic in microeconomics. If both buyers and sellers expect the price to fall next period, the price would rise in the current period. The opportunity cost of your decision to take this exam is what you would have done if you hadn't taken this exam. O According to Professor Lionel Robbins, an economic problem would arise if there were multiple ends that could be ranked in order of importance and limited means that could be applied to more than one end, Some economic historians assert that inventive genius spurred the Industrial Revolution. This explanation embodies the idea that technological progress is exogenous and economic development is endogenous. a student made a mistake while performing gram staining. what is the best explanation for a gram-negative bacterium appearing purple after performing a gram stain? glycolysis results in a net production of which of the following from each molecule of glucose? (in java )You are given an array of integers numbers and two integers left and right. You task is to calculate a boolean array result, where result[i] = true if there exists an integer x, such that numbers[i] = (i + 1) * x and left x right. Otherwise, result[i] should be set to false.ExampleFor numbers = [8, 5, 6, 16, 5], left = 1, and right = 3, the output should be solution(numbers, left, right) = [false, false, true, false, true].For numbers[0] = 8, we need to find a value of x such that 1 * x = 8, but the only value that would work is x = 8 which doesn't satisfy the boundaries 1 x 3, so result[0] = false.For numbers[1] = 5, we need to find a value of x such that 2 * x = 5, but there is no integer value that would satisfy this equation, so result[1] = false.For numbers[2] = 6, we can choose x = 2 because 3 * 2 = 6 and 1 2 3, so result[2] = true.For numbers[3] = 16, there is no an integer 1 x 3, such that 4 * x = 16, so result[3] = false.For numbers[4] = 5, we can choose x = 1 because 5 * 1 = 5 and 1 1 3, so result[4] = true.Input/Output[execution time limit] 3 seconds (java)[input] array.integer numbersAn array of integers.Guaranteed constraints:1 numbers.length 100,1 numbers[i] 106.[input] integer leftAn integer representing the lower bound for x.Guaranteed constraints:1 left 104.[input] integer rightAn integer representing the upper bound for x.Guaranteed constraints:1 left right 104.[output] array.booleanA boolean array result described above. You have a lens with a focal length of 9.17 cm. You wish to use the lens to make an image 15.0 cm to the right of the lens. How far to the left of the lens would you place the object?
