Answer:

force = 6.53× 10^{-7} N

Explanation:

Provided data

downward force = 0.60 m

mass m = 10^{-7} kg

distance h = 0.40 m

to determine

magnitude of the downward force

solution

we know here mg is apply 0.4 m away from support and

thus applied force is d = 0.6 m from support

therefore

by balancing torque we can compute force

as

force = mass × g × h / d

substituting the values

force = mass × g × h / d

force = ( 10^{-7} × 9.81 × 0.4 ) / 0.6

force = 6.53× 10^{-7} N

serg [3582]

Infiltration

Explanation:

The feature of the hydrologic cycle most impacted by impervious surfaces like concrete and asphalt is infiltration.

  • Infiltration is crucial within the hydrologic cycle.
  • Concrete and similar materials hinder water absorption into the ground.
  • This adversely affects existing groundwater systems.
  • A rise in surface runoff can occur, leading to potential flooding.
  • Infiltration plays a pivotal role in the water cycle.
  • It supplies water to plant roots and replenishes groundwater reserves.
  • Impervious surfaces disrupt this natural process.
