Answer:
151.9 N
Explanation:
Force = mass x acceleration
Acceleration due to gravity is 9.8 m/s^2 (you should memorize this number).
F = ma
F = (15.5)(9.8)
F = 151.9
Answer:
nitrogen, phosphorus, potassium, and calcium
Explanation:
Just put it.
- Angle (θ) = 60°
- Force (F) = 20 N
- Distance (s) = 200 m
- Therefore, work done
- = Fs Cos θ
- = (20 × 200 × Cos 60°) J
- = (20 × 200 × 1/2) J
- = (20 × 100) J
- = 2000 J
