For n resistors in series, the equivalent resistance is given by the sum of the resistances:
In this problem, we have three resistors, so the equivalent resistance of the load is the sum of the resistances of the three resistors:
Answer:
54 J
Explanation:
Work done = force * displacement
= 18 *3
= 54 J
Answer:
When the source of pollution is widely distributive in nature, it is called as the Non-point source pollution, for example, <em>acid rain</em>.
Explanation:
the source of pollution when is <em>not concentrated over a particular area</em> or any particular defined pinpoint is termed to be as the Non - point source pollution.
this type of pollution is very hard to be monitored or controlled due to its nature of widely distributive nature of the origin. It has <em>several pathways</em> for the effect to undertake and thus the control over the effect is <em>not easily accessible. </em>
For example, during rain, the tree fall off can enter water stream from any source, either be it open lake or ponds or even street fall offs.
