16. To find the mass of an object using the weight formula, we can rearrange the equation:
Weight = Mass x Gravity
Mass = Weight / Gravity
Mass = 120 N / 9.81 m/s² ≈ 12.24 kg.
So the closest answer is:
**d. 12 kg**
---
17. A skydiver needs a parachute to land safely because:
**a. It increases air resistance and slows the skydiver to a safe speed**
---
18. The force that causes objects falling near Earth's surface to slow down is:
**c. Air Resistance**
---
19. If a golf ball and a baseball are dropped in the absence of air resistance, they will hit the ground at the same time because:
**a. they will hit at the same time**
---
20. If a feather and a baseball are dropped in the presence of air resistance, the baseball will hit the ground first because it is less affected by air resistance compared to the feather:
**a. the baseball**
Weight = Mass x Gravity
Mass = Weight / Gravity
Mass = 120 N / 9.81 m/s² ≈ 12.24 kg.
So the closest answer is:
**d. 12 kg**
