Question
Name any two sources which causes air pollution due to Suspended Particulate Matter $(\text{SPM}).$
✓
Answer
Two sources which cause air pollution are as follows:
$i.$ Automobiles which bum diesel and petrol, produce $\text{SPM}$ which remain suspended in air and reduce visibility. When inhaled, they cause diseases.
$ii.$ Industrial activities like manufacturing of steel and mining give out $\text{SPM}$ which also pollute the atmosphere.

→Read the paragraph and answer the questions following it. Water is essential for life. Without water there would be no life. We usually take water as granted for its purity, but we must ensure the quality of water. Pollution of water originates from human activities. Through different paths, pollution reaches to
ground water. Easily identified source or place of pollution is called as point source, e.g.– municipal and industrial discharge pipes, where pollutants enter the water source. Non–point sources of pollution are those where a source of pollution can not be easily identified, e.g.– agricultural run off, acid rain etc.
$i.$ How do you classify the various sources of water pollution?
$ii.$ What are the point sources of water pollution?
$iii.$ Name any two non-point sources of water pollution?

An electric bell has an electromagnet fitted in its circuit. One or two electromagnets made of wires coiled on iron pieces are fixed on the bell case. When the bell switch is pressed, the current flows through these coils, and these become magnets. These magnets attract a metal strip, which has a hammer attached to its end near the gong of the bell. The metal strip moves fast towards the electromagnet, and the hammer strikes the gong. At the same time, with the movement of the metal strip from its position, the electric circuit breaks, the magnet stops working, and the strip moves back to its original position.
Q.1. When does the electromagnet work?
Q.2. When the flow of current stops in the coil, what happens to the magnetic field around the electromagnet?
Q.3. What is the industrial use of an electromagnet?
