Question

Tell about POLLUTION........​

Answer 1

Answer:

Pollution

Explanation:

Final Answer : Option B:

Understanding :

1) Forces will be due to Pressure ( Both atmospheric and Change in height of liquid) and Surface Tension.

2) Net Force = Force (Pressure) - Surface Tension Force

(- ) sign since both are opposite to each other.

3) Since, Pressure will change due to height,

so that we will write Pressure in terms of distance and integrate it to height h in liquid.

Formula :

1) Surface Tension Force = T ( 2R)

For Calculation see Pic attached to it.

Answer 2

Answer:

Pollution is the introduction of contaminants into the natural environment that cause adverse change. Pollution can take the form of chemical substances or energy, such as noise, heat, or light. Pollutants, the components of pollution, can be either foreign substances/energies or naturally occurring contaminants.
