1. List three states in India where earthquakes are more likely to strike.
The earthquake design code of India splits India into four seismic zones, according to the most recent edition of the seismic zoning map of India. Jammu and Kashmir, Gujarat, and Assam are the most earthquake-prone states in India, according to the report. These are the three states with the highest risk of earthquakes. The Western and Central Himalayas, North and Middle Bihar, the North-East India region, and the Andaman and Nicobar Islands are all earthquake-prone locations in India.
2. Suggest three measures to protect ourselves from lightning.
We may safeguard ourselves from lightning in a variety of ways. During a thunderstorm, open places are extremely dangerous. If a person is in an open area, he should seek shelter in a house or other safe structure that is protected from lightning. During a thunderstorm, we should avoid raising an umbrella over our heads. Lightning strikes can damage TV antennae and dish antennas.
3. Why do two charged bodies attract or repel?
Two electrical charges of the same polarity generate an electric field and the forces that ensue. The two charges seem to repel one another. When a positive and negative charge contact, their forces act in the same direction, from positive to negative charge, attracting the two charges together. Like charges repel each other and unlike charges attract each other. For a detailed explanation, visit Vedantu.
4. Sometimes, a crackling sound is heard while taking off a sweater during winters. Explain.
Wool, which is a poor conductor of electricity, is used to make sweaters. When we wear the sweater, the wool comes into touch with our bodies, causing friction as the body rubs against the wool. As a result of the rubbing, the wool becomes charged, and a force is felt between the wool and our bodies. During the winter, we hear a cracking sound as we remove our sweaters owing to this energy.
