02.7 · 2 marks Interlocking Gears and Rotation Explain what happens to gear B when the child applies the force to gear A. 04.1 · 2 marks Water Pressure with Increasing Depth The depth of the submarine increases. Explain what happens to the pressure on the submarine. 04.2 · 4 marks Mariana Trench Depth from Pressure The submarine moved from the surface of the water to the bottom of the Mariana Trench. The change in pressure was 110 000 kPa.... 05.1 · 1 mark Tension in the Trolley String Figure 10 shows the force F which acts through the string. What name is given to force F? 05.3 · 3 marks Acceleration from Distance and Time The student held the trolley stationary and then released it. The trolley moved along the runway with a constant acceleration.... 07.1 · 3 marks Distance from a Velocity–Time Graph Determine the distance travelled by the train in the first 600 s of the journey. 07.2 · 3 marks Graph Gradient, Deceleration and Braking Force Explain what happens to the braking force as the train decelerates. Use information from Figure 12. 07.4 · 6 marks Braking Distance from Force and Mass Another train travels at a speed of 60 m/s. A constant braking force of 270 000 N causes the train to decelerate and stop. mass... 07.5 · 3 marks Alcohol, Reaction Time and Stopping Distance It is illegal for train drivers to drink alcohol before driving a train. Explain how drinking alcohol would affect the stopping...
