Why the resistance of an ideal ammeter is zero? An ideal ammeter would have zero resistance so that there was no voltage drop across it, and so it would not affect a circuit into which it was placed. A zero resistance will not change the resistance of a circuit is placed in series and hence […]

What is magnetism and its types? There are six basic types of magnetization: (1) diamagnetism, (2) paramagnetism, (3) ferromagnetism, (4) antiferromagnetism, (5) ferrimagnetism, and (6) superparamagnetism. Diamagnetism arises from the orbiting electrons surrounding each atomic nucleus. What are 4 types of magnets? Permanent Magnets. There are typically four categories of permanent magnets: neodymium iron boron […]

Why is the asthenosphere so important to plate tectonics? The asthenosphere is now thought to play a critical role in the movement of plates across the face of Earth’s surface. Some observers have described the asthenosphere as the ‘lubricating oil’ that permits the movement of plates in the lithosphere. … What are the main features […]

What are the 5 advantages of greenhouse gases? Here are a few advantages of the greenhouse effect on our planet earth: Maintain Temperature Levels. They help in maintaining a certain temperature level on the earth’s surface. Block Harmful Radiations. They help in blocking harmful solar radiation from reaching the planet’s surface. Maintains Water Level. How […]

Why does not a running bicycle fall? The answer is that you slip and fall and no gyroscopic force of the wheels or anything else prevents this. The answer is that if you try to turn (lean) even a little bit too much the sand flows under the bike wheel and doesn’t provide enough friction […]

Can you hit a piece of tissue in mid air? Why can’t he hit a piece of tissue paper in midair with the same amount of force? The boxer can only hit the tissue paper with a force as large as the tissue paper can exert on the boxer, and the low-mass tissue can only […]

How do you transform your energy in your day to day life? Transform your energy, transform your life….To create space for diffused thinking, plan time in your day for whatever puts your brain in a neural resting state, which can include: Walking outside. Listening to music. Taking a long warm shower. Playing with your dog […]

What cell organelles are found in both cells? Core organelles are found in virtually all eukaryotic cells. They carry out essential functions that are necessary for the survival of cells – harvesting energy, making new proteins, getting rid of waste and so on. Core organelles include the nucleus, mitochondria, endoplasmic reticulum and several others. What […]

How long would it take to walk around the whole world? 8,300 hours How many miles do you need to get a free flight? How many miles do you need to have for a free flight by airline? We sampled award miles needed for a one-way domestic flight, and found that consumers need between about […]

What would you see if you visited Saturn? If you look back at the sky during your journey in Saturn’s upper atmosphere, the sky would appear blue in color. You would even see Saturn’s rings in the sky. In the bottom-most region of Saturn’s atmosphere, the pressure would rise to about 10 to 20 bar. […]
