Can you please answer and show work for the following physics questions? Will be happy to leave a great review. Thank you in advance.

7. A block of lead has a weight of 24.500 newions and a volume of 0.221 cubic meter. The density of the lead block is most nearly (a) 5970 kg/m (b) 11.300 kg/m3 (c) 21.500 kg/m (d) 111.000 kg/m3 8. A 25-newion force is applied to a wrench, as shown. The magnitude of the torque that this force produces equals 25 N (a) 1.5 N.m 30 (b) 3.0 N.m (c) 150 N.m -12 cm- (d) 300 N-m 9. The graph is a plot of the velocity versus time for an object moving in a straight line. The a position of the object at 7 = 0 seconds is 0 meters. At what time after 1 = 0 seconds 20 does the object again pass through its initial position? 10 (a) 1 second 2 3 Velocity in meters per second (b) Between 1 and 2 seconds -10 (c) 2 seconds -20 - (d) 3 seconds Time in seconds 10. A pump lifted 50.0 kilograms of water at a constant velocity a vertical distance of 10.0 meters in 75.0 seconds. The average power consumption of the pump is (a) 6.67 W (b) 16.7 W (c) 32.7 W (d) 65.4 W 11. A rope pulls a 5.2-kg block upward with a constant acceleration of 5.0 meters per second squared: The tension in the rope is (a) 26 N (b) 51 N 10) 63 N (d) 77 N 12. The efficiency of the first machine lis 80.0 percent and the efficiency of the second machine is 50.0 percent. The amount of work done by the second machine is (2) 182 J 455 J MZ-IOPS Work # MZ-IOD3 (b) 228 3 out (C) 364 ] #2 (d) 455 3
