TEA [102]

Answer:

Reverse Osmosis and UV Treatment

Explanation:

Reverse Osmosis, commonly known as RO, process is very effective in removing salt content from water. This process is known as desalination. IN RO, a partially permeable membrane is used to remove unwanted molecules, ions, and large particles. RO will take care of both desalination and purification of water.

Further UV treatment can be done to kill any remaining microorganisms as these microorganisms can not withstand UV radiation.

For an object moving with constant negative acceleration, draw the following:
Tcecarenko [31]

Answer:

Kindly find the graphs attached

Explanation:

For figure 1: There is a steady increase in the position of the object as time increases. This is because despite the negative acceleration (deceleration), the object continues to move and cover more ground as time goes by.

<em>The straight line graph is observed because the acceleration is constant  and not varying.</em>

For Figure 2: The graph of velocity vs time will have an inverted nature. This is because since the object is decelerating, it is reducing in its velocity as time goes by (increases). <em>This is also in a straight line since the deceleration is constant.</em>
