O The mechanical energy of the student stays constant. 0 The loss in gravitational potential energy always equals the gain in kinetic energy. 0 The gravitational potential energy always equals the kinetic energy. 0 The kinetic energy of the student increases The given four graphs show the relation between the change of length of an object and the internal restoring force developed. Which of the following graphs best illustrates Hooke's law? O P N 10'CThe following diagram: show different teat: you can die with cuts on ramps. You want to test this hypothesis: the heavier a cart and its load is, the greater its speed at the bottom of the ramp. Which three tests would 1gurou use? Question 11 (3 points) A force of 50 N acts on the block at the angle shown. The block moves a horizontal distance of 3.0 m. 50 N 30- Surface The work done is closest to Oo 1.3 x 102 J O 1.5 x 102 J O 2.7 x 102 J ( 4.5 x 102 JQuestion 4 {1 point] Where in the flight clues mechanical energyr equal the mechanical energy.r at c? {assume no friction} 3 tar t [141i uh Question 10 (2 points) A brick falls from the top of a skyscraper under construction.
