The graph shows how the resultant force varies with time. Which graph is the speed-time graph for the object? A B C D

3 4 Block A and block B are connected by a light inextensible string. A force of 12 N acts on block A as shown. Given that the floor is smooth, what is the tension in the string connecting block A and block B? A 2.0 N B 4.0 N C 8.0 N D 12 N 5 Which of the following is not an example of an action -reaction pair based on Newton’s laws of motion? A A student pulling a bag forward, the bag pulling the student backwards. B Weight of a book resting on the table, and the normal contact force the table exerts on the book. C Driving wheel of a bicycle exerting friction on the road, and the road exerting friction on the wheel. D Earth pulling a skydiver with gravitational force, and skydiver pulling Earth with a gravitational force. 6 The weight of a rock on Venus is less than its weight on Earth. How do the mass of the rock and gravitational field strength on Venus compare with their respective values on Earth?
