LONG-ANSWER QUESTIONS: Answer these questions. 1. Draw a labelled diagram of a gold-leaf electroscope. Describe how you will use it to detect a charge, measure a charge, and find the nature of the charge. 2. Explain how lightning occurs between two clouds during a storm. 3. Explain the process of lightning striking a building or tree, 4. In what ways is lightning useful? 5. Explain how an earthquake occurs. 6. List three things you will do during an earthquake.
Answers
Answer:
1. I can tell you how electroscope detect the charge
an electroscope is a device used to dedicate the presence of electric charge and to dedicate that type of charges of object and quality of charge present on the charged object
if a charged body is brought in contact with the electroscope the leaves diverge after getting charged even if the charge body is move away from the electroscope it remains charged and the leaf remains diverge
if an uncharged body is brought in contact with the letter of scope no repulsion is observed between it leaves thurs you can see how electrical charge can be transferred from the charged body to another through a metal conductor
2. During thunderstorm, when a charged cloud passes over an uncharged cloud, uncharged cloud acquires opposite charge by induction and the two clouds attract. When they combine with each other, they produce a large amount of heat, light and sound also known as lightning.
5.Earthquakes are caused due to sudden tectonic movements in the earth's crust. When the tectonic plates slide over one another, there is a cause of orogeny which results in earthquakes and volcanoes. These disturbances cause vibrations that spread in all directions.
6. If you are INDOORS -- STAY THERE! Get under a desk or table and hang on to it (Drop, Cover, and Hold on!) or move into a hallway or against an inside wall. STAY CLEAR of windows, fireplaces, and heavy furniture or appliances.
