Answer 1

Here are the filled answers and short explanations for each scenario. Work = F · d · cos(θ). If force and displacement are in the same direction θ = 0° so W = F·d; if perpendicular θ = 90° so W = 0.

1) Opossum hangs from a branch
- Force: 5 N up; Distance: 0 m up
- Work: 0 J (no displacement → no work)

2) Horse carries a pack
- Force: 50 N up; Distance: 5 m left
- Work: 0 J (force is upward, displacement is horizontal → perpendicular → no work by that upward force)

3) Frog jumps onto a rock
- Force: 4 N up; Distance: 0.2 m up
- Work: 4 × 0.2 = 0.8 J

4) Ant carries a crumb upward
- Force: 0.01 N up; Distance: 0.05 m up
- Work: 0.01 × 0.05 = 0.0005 J (5.0 × 10^−4 J)

5) Lifting a carrot
- Force: 1 N up; Distance: 0.1 m up
- Work: 1 × 0.1 = 0.1 J

6) Heron pulls a fish out of the water
- Force: 5 N up; Distance: 0.5 m up
- Work: 5 × 0.5 = 2.5 J

7) Dog carries a puppy
- Force: 9 N up; Distance: 2 m right
- Work: 0 J (force vertical, displacement horizontal → no work by that vertical force)

8) Lizard catches an insect
- Force: 0.01 N left; Distance: 0.05 m left
- Work: 0.01 × 0.05 = 0.0005 J (5.0 × 10^−4 J)

9) Beaver pushes wood toward a dam
- Force: 2 N left; Distance: 0.5 m left
- Work: 2 × 0.5 = 1.0 J

If you want this arranged in a table format or explained step-by-step for any one item, I can do that.
