What front usually happens and is over quickly? Occluded Front Because cold fronts move faster, the cold front is likely to overtake the warm front. This is known as an occluded front. At an occluded front, the cold air mass from the cold front meets the cool air that was ahead of the warm front. […]
How do huge stars die?
How do huge stars die? All stars eventually run out of their hydrogen gas fuel and die. When a high-mass star has no hydrogen left to burn, it expands and becomes a red supergiant. While most stars quietly fade away, the supergiants destroy themselves in a huge explosion, called a supernova. Why do most stars […]

What is the advantage of PIN photo diodes?
What is the advantage of PIN photo diodes? Advantages and Disadvantages of PIN Photodiode The advantage is its high-frequency response and its frequency response is also greater than Cadmium – Sulphide photodetector. It is inexpensive and the response time is in nanoseconds which make it appropriate for electronic circuitry. What are PIN diodes used for? […]
What are the methods of producing induced emf?
What are the methods of producing induced emf? The induced emf can be produced by changing : (i) the magnetic induction (B), (ii) area enclosed by the coil (A) and. (iii) the orientation of the coil (θ) with respect to the magnetic field. What is the use of induced emf? A motor has coils turning […]

What are the best electrodes for electrolysis?
What are the best electrodes for electrolysis? Steel and iron are the most commonly used for electrolysis of water. These electrodes are used as anode and it is sacrificed in electrolysis, as the anode rusts (get oxidized) and the cathode de-rusts (get reduced). What factors affect rate of electrolysis? There are many factors that affect […]
When water evaporates What does it turn into?
When water evaporates What does it turn into? Evaporation happens when a liquid substance becomes a gas. When water is heated, it evaporates. The molecules move and vibrate so quickly that they escape into the atmosphere as molecules of water vapor. How fast does a glass of water evaporate? 1.2 hours What are some real […]
Can electric current flow through human body?
Can electric current flow through human body? The human body is a good conductor of electric current simply because it is 70% water. Human tissue is very sensitive to the flow of electric current and is more susceptible to electric shock when wet. Does human body have current? Electricity is everywhere, even in the human […]
