Final answer:
The statements about displacement, forces in outer space, and position vs time graphs were assessed as false, respectively.
Step-by-step explanation:
Here are answers to the physics problems you've asked about:
Displacement Comparison
For the question True or False-A person walks 2 blocks east and 5 blocks north. Another person walks 5 blocks north and then two blocks east. The displacement of the first person will be more than the displacement of the second person. The answer is b. False. Displacement is a vector that shows the shortest path from the initial to the final position. Both individuals will have the same displacement since they start and end at the same points, just in a different order.
Forces in Outer Space
The statement An external force is required to set a stationary object in motion in outer space away from all gravitational influences and atmospheric friction is a. True. According to Newton's First Law, an object at rest will stay at rest unless acted upon by an external force. Even in the vacuum of space without gravity and atmosphere, a force is required to change the state of motion of an object.
Position vs Time Graph
Regarding the statement The position vs time graph of an object that is speeding up is a straight line, the answer is b. False. When an object speeds up, the slope of its position vs time graph increases, resulting in a curved line, not a straight one.
