Here are the answers to the questions based on the information provided:

Question 3: What is the difference between speed and velocity?
Answer: b - Velocity has direction.

Question 4: When balanced force acts on an object, the net force that results is
Answer: c - equal to zero.

Question 5: Which animal's speed is the greatest?
To find the speed, we use the formula: Speed = Distance / Time.

  • Gray fox: 73 km / 1.05 h = 69.52 km/h
  • Gazelle: 68 km / 0.85 h = 80 km/h
  • Rabbit: 70 km / 1.25 h = 56 km/h
  • Cheetah: 85 km / 0.75 h = 113.33 km/h
  • Giraffe: 60 km / 1.15 h = 52.17 km/h
  • Antelope: 93 km / 0.95 h = 97.89 km/h

Answer: a - cheetah

Question 6: If you keep a gas's temperature constant, how would you increase the volume of the gas?
Answer: b - You would decrease the pressure.

Question 7: An object moves a distance of 10 meters in 5 seconds. What is the average speed of the object?
Average Speed = Distance / Time = 10 m / 5 s = 2.0 m/s
Answer: d - 2.0 m/s

Question 8: Match each description or picture with its correct term.

  1. How far an object has traveled. -> b. Distance
  2. The straight line difference between the starting point and the ending point. -> a. Displacement
  3. 5 meters -> b. Distance (assuming this refers to distance only)
  4. The black arrow in the picture below. -> a. Displacement (assuming it's indicating direction)
  5. The blue dashed lines in the picture below -> b. Distance (if it represents a measured path without direction)
  6. 5 m North -> a. Displacement (because it includes direction)

Keep in mind that the last part may depend on the specific context or images referred to, but the provided answers align with common definitions of distance and displacement.
