8. [-/4 Points] DETAILS A 1901 kg car skids to a stop across a horizontal road surface that has a coefficient of friction of #x = 0.851 . Determine the acceleration of the car. The magnitude of the acceleration of the car is12. [-/12 Points] DETAILS A pulsar has an estimated average density of 5.5e+17 kg/m . A pulsar is a type of neutron star. That density is much higher than anything on Earth. If you had 1 cm cube of this material what would its mass be? The mass would be kg. If you could apply a net force of 250000 N to the cube, what would be the acceleration of the cube? The acceleration would be mm/s2 For comparison, a 1 cm cube is about the size of a sugar cube. 250000 N is approximately the pulling force from a railroad locomotive which has a typical mass of 1 x105 kg. If we could apply the same 250000 N force to a 4.00 g sugar cube, the sugar cube's acceleration would be km/s21. [-/28 Points] DETAILS Figure A In Out Figure B Out 1. Consider the two pictures with the three pipes connected in different ways. Which of the two pictures has the pipes connected so the fluid flow is in series through the pipes? O Figure B O None of the figures have series fluid flow. O Figure A 2. Which of the pictures has the pipes connected so that the fluid flow is in parallel through the pipes? O Figure A O Figure B O None of the figures have parallel fluid flow. 3. Each pipe has a fluid resistance of 21100 Pa.s/ms. Consider the case where the three pipes are connected in series. What is the total fluid resistance of the three pipes in series? Series resistance is 4.Each pipe has a fluid resistance of 21100 Pa.s/m3. Consider the case where the three pipes are connected in parallel. What is the total fluid resistance of the three pipes in parallel? Parallel resistance is Note: The connecting blocks at the ends of the pipes have negligible fluid resistance so they can be ignored.8.
