Question 6 V1 V2 = 0 m1 initial -> m1 m2 m2 final If m1 =(0.500±0.005) kg, M2 =(1.000±0.005) kg, Vị =(0.25±0.01) m/s and Vf =(0.07±0.01) m/s. Calculate the impulse during the collision for two carts system: Your Answer: Answer units

A white billiard ball with mass mw = 1.58 kg is moving directly to the right with a speed of v = 2.87 m/s and collides elastically with a black billiard ball with the same mass mb = 1.58 kg that is initially at rest. The two collide elastically and the white ball ends up moving at an angle above the horizontal of θw = 32° and the black ball ends up moving at an angle below the horizontal of θb = 58° What is the final speed of the white ball? What is the final speed of the black ball? What is the magnitude of the final total momentum of the system? What is the final total energy of the system?

A white billiard ball with mass mw = 1.32 kg is moving directly to the right with a speed of v = 2.9 m/s and collides elastically with a black billiard ball with the same mass mb = 1.32 kg that is initially at rest. The two collide elastically and the white ball ends up moving at an angle above the horizontal of θw = 69° and the black ball ends up moving at an angle below the horizontal of θb = 21°. 1. What is the final speed of the white ball? 2. What is the final speed of the black ball? 3. What is the magnitude of the final total momentum of the system? 4. What is the final total energy of the system?

One mole of a monatomic ideal gas ( Cv = 3/2R ) has an initial pressure, volume, and temperature of P0, V0, and 400 K, respectively. It undergoes an isothermal expansion that triples the volume of the gas. Then, the gas undergoes an isobaric compression back to its original volume. Finally, the gas undergoes an isochoric increase in pressure, so that the final pressure, volume, and temperature are P0, V0, and 400 K, respectively. a) calculate delta U, W, and Q ( including the algebraic signs ) for each of the three steps and the whole cycle. Show step by step.b) how much heat enters the gas and how much leaves the gas each cycle? Please show step by step with formulas used. Thank u

Johnson Filtration, Inc., provides maintenance service for water-filtration systems throughout southern Florida. Customers contact Johnson with requests for maintenance service on their water-filtration systems. To estimate the service time and the service cost, Johnson's managers want to predict the repair time necessary for each maintenance request. Hence, repair time in hours is the dependent variable. Repair time is believed to be related to three factors, the number of months since the last maintenance service, the type of repair problem (mechanical or electrical), and the repairperson who performed the service. Data for a sample of 10 service calls are reported in the table below. Repair Time in Hours Months Since Last Service Type of Repair Repairperson 2.9 2 Electrical Dave Newton 3.0 6 Mechanical Dave Newton 4.8 8 Electrical Bob Jones 1.8 3 Mechanical Dave Newton 2.9 2 Electrical Dave Newton 4.9 7 Electrical Bob Jones 4.2 9 Mechanical Bob Jones 4.8 8 Mechanical Bob Jones 4.4 4 Electrical Bob Jones 4.5 6 Electrical Dave Newton (a) Ignore for now the months since the last maintenance service (x1) and the repairperson who performed the service. Develop the estimated simple linear regression equation to predict the repair time (y) given the type of repair (x2). Let x2 = 0 if the type of repair is mechanical and x2 = 1 if the type of repair is electrical. (Round your numerical values to three decimal places.) ŷ = (b) We see that ____% of the variability in the repair time has been explained by the type of repair. (Round your answer to two decimal places.) (c) Ignore for now the months since the last maintenance service and the type of repair associated with the machine. Develop the estimated simple linear regression equation to predict the repair time given the repairperson who performed the service. Let x3 = 0 if Bob Jones performed the service and x3 = 1 if Dave Newton performed the service. (Round your numerical values to three decimal places.) ŷ = (d) We see that ________% of the variability in the repair time has been explained by the repairperson. (Round your answer to two decimal places.)
