U = I × R = 20A × 12 Ohm =240V
They become flooded
Explanation:
Pavements using concretes and asphalts make water to runoff their surface. These surfacing materials prevents infiltration of water into the soil.
- Usually from every precipitation, a proportions goes into the soil as infiltration.
- Paved surfaces prevents infiltration of water into the soil.
- All the surface runoff will eventually move into nearby streams and rivers thereby increasing the volume of water in them.
- This enables rivers to become inundated and in the process they flood their banks and surrounding areas.

Answer:
Correct Answer: Option B
Explanation
V.R = 1sinθ=1sin30=21sinθ=1sin30=2
M.A = E×V.R100=50×2100=1E×V.R100=50×2100=1
Effort = loadM.A=1201=120N
