Why is the electric field inside an insulator not zero? This is attributed to the fact that the electrons are loosely bound to the nuclei and they are free to rearrange themselves until the net field becomes zero. But in an insulator the electrons are tightly bound to the nuclei. So they can resist movement […]
Does a rising GDP benefit everyone?
Does a rising GDP benefit everyone? Answer:When a country’s GDP is high it means that the country is increasing the amount of production that is taking place in the economy and the citizens have a higher income and hence are spending more.

What factors affect an electromagnet?
What factors affect an electromagnet? Factors that affect the strength of electromagnets are the nature of the core material, strength of the current passing through the core, the number of turns of wire on the core and the shape and size of the core. What happens to a compass in a magnetic field? A compass […]
When the heat transfer into a system is more than the work transfer out of the system?
When the heat transfer into a system is more than the work transfer out of the system? This energy is neither heat nor work but it is called as internal energy. As the heat transfer is more that work transfer then the internal energy (ΔE) increases. How can the internal energy of a closed system […]
What is the sum of two vectors called?
What is the deadliest volcanic eruption?
What is the deadliest volcanic eruption? Here are the five deadliest volcanoes in history: Tambora, Indonesia (1815) The largest recorded volcanic eruption in history, Tambora caused enough starvation and disease to kill approximately 80,000 people. Krakatau, Indonesia (1883) Pelée, Martinique (1902) Ruiz, Colombia (1985) Unzen, Japan (1792) Did Pompeii have a tsunami? Although records suggest […]
How can you tell how deep a well is dropping a rock?
What is better 2 stroke or 4 stroke?
What is better 2 stroke or 4 stroke? Because 2-stroke engines are designed to run at a higher RPM, they also tend to wear out faster; a 4-stroke engine is generally more durable. That being said, 2-stroke engines are more powerful. Two-stroke engines are a much simpler design, making them easier to fix. They do […]
What is the soft weak and plastic like layer?
What is the soft weak and plastic like layer? The movement of the lithospheric plates is facilitated by a soft, weak and plastic-like layer is called asthenosphere. Do the plates in this activity have the same density? Answer. Answer: Explanation: They are denser compared to continental crust, meaning they have more mass per unit volume. […]
