A student (weight = 400 N) is in an elevator. The student steps onto a scale and sees a mass reading of 350 N. Based on the difference between the real versus apparent weights, what can you conclude about the elevator's motion? Select one: 0 a. The elevator is moving with constant velocity upwards. O b. The elevator is accelerating downwards. O c. The eievator is accelerating upwards. O d. The elevator is moving with constant velocity downwards. A curious physicist climbs a small mountain and performs an experiment. The physicist measures the force of gravity acting on different mass objects. Based on this experiment, the physicist noticed that there is a linear relationship between the force of gravity, and the mass of the object being examined. This data is shown in the following graph. HI\" (I!) What does the SLOPE of this graph represent? Select one: 0 a. The universal gravitational constant. 0 b. The gravitational field strength. O c. The mass of the pEanet {Earth}. C) d. The mass of the object being examined. \fA stack of three heavy Physics textbooks are laying flat on a table. which of the following would result in an INCREASE in the coefficient of friction acting between the stack of textbooks and the table? Select one: Q a. Change the surface of the table to a different material. O b. Add a textbook onto the pile to increase the mass. O c. Open the textbooks to increase the amount of contact area. O (1. Remove a textbook from the pile to decrease the mass
