Answer:

Explanation:

When the downward force of gravity on a falling parachutist is exactly equal to the upward force of air resistance , net force on the parachutist will be zero . As a result of it , there will be no acceleration in his downward motion . In other words , his downward velocity will not be either increasing or decreasing . It will remain steady .

So option b) is correct.

How does a meander form in a river?
AlexFokin [52]

Answer:

A meander forms in a river by eroding laterally, to the right side then the left side and the left side again, this forms large bends, which then horseshoe like loops called meanders. The force of the water then erodes and undercuts the river bank on the outside of the bend which is where the water flows and it has the most energy due to the decreasing friction.

Answer:

In groundwater replenishment system in Orange County, CA, treated domestic sewer is injected into underlying aquifers using injection wells.

False

Explanation:

In the orange country's water treatment system techniques like micro filtration  , and ultraviolet ( UV ) , reverse osmosis (RO)  disinfection with hydrogen peroxide are used for purification . Generally at the source polluted water is first micro - filtered for the removal of small suspended particles bacteria , protozoa ,  and harmful virus from water . The water is then filtered via RO , which removes salts , pesticides , viruses  and most organic compounds are passed in the presence of the forced water via thin plastic membrane , and in the final stage , the water is treated with hydrogen peroxide and UV light as a precautionary measure.
