Two bullets with identical masses of 300 g are fired with identical velocities of 300 m/s into two walls made of different materials. Bullet #1 enters wall #1 and comes to a complete stop in 6,0 x 10 2 s. Bullet #2 enters wall #2 and comes to a complete stop in 6.0 x 10 s. Compare the momentum change of bullet #1 with bullet #2 and compare the impulse that occurred on both. Select one: O a. Bullet #1 underwent the larger momentum change but both underwent the same impulse O b. Both had the same momentum change but bullet #1 underwent the larger impulse. O c. Both had the same momentum change but bullet #2 underwent the larger impulse. O d. Both had the same momentum change and both underwent the same impulse Two bullets with identical masses of 300 g are fired with identical velocities of 300 m/s into two walls made of different materials. Bullet # 1 enters wall #1 and comes to a complete stop in 6.0 x 10 - s. Bullet #2 enters wall #2 and comes to a complete stop in 6.0 x 10" s. Quantitatively, compare the force on bullet #1 as compared with bullet #2 and say which bullet, if any suffered the greater deformation. Select one: O a. Bullet #1 had 10 times as much force as bullet #2 and bullet #2 suffered the greater deformation O b. Bullet #2 had 10 times as much force as bullet #1 and bullet #1 suffered the greater deformation O c. Bullet #1 had 10 times as much force as bullet #2 and bullet #1 suffered the greater deformation O d. Bullet #2 had 10 times as much force as bullet #1 and bullet #2 suffered the greater deformation A clerk working at a local food store is asked to retrieve the empty shopping carts left outside by shoppers. Each cart has a mass of 20 kg The clerk places a carts, which are locked together, close to the entrance on a slight incline. The clerk gathers another 12 carts and pushes them toward the store entrance. Meanwhile, the first 8 carts roll toward the 12 carts with a speed of 2 3 m/s. When the carts collide, they all come to a complete stop. At what speed were the 12 carts moving, just before impact? Select one: O a. 2.88 x 10-2 m/s O b. 2.90 x 10-1 m/s O c. 1.53 m/s O d. 3.45 m/sThe 1740 kg car travelling north on an icy test area was crashed into the 2000 kg car travelling west. The test designers found that the two vehicles locked together on impact and slid at 9.0 m/s at 350 west of north. What was the speed of the 1740 kg car just before impact? Select one: O a. 16 m/s O b. 11 m/s O c. 8.5 m/s O d. 5.9 m/sTwo positive charges, q1 of 2.0 x 10 - C and q2 of 3.0 x 10 5 C, are separated by 3.0 m. The electric force between them is Select one: O a. 6.0 x 10-3 N (repulsion) O b. 2.0 x 10-3 N (repulsion) O c. 6.0 x 10 3 N (attraction) O d. 2.0 x 10 3 N (attraction) In a Millikan experiment, a small sphere with a mass of 8.16 x 10715 kg is suspended between plates that are 2.00 cm apart. This sphere is maintained at a potential difference of 1.00 x 10- V. What is the net charge on the small sphere? Select one: O a. 1.60 x 10-19 C O b. 1.60 x 10-18 C O c. 8.00 x 10-17 C O d. 4.00 x 10 12 C
