Which country has the most tundra? The tundra is a treeless polar desert found in the high latitudes in the polar regions, primarily in Alaska, Canada, Russia, Greenland, Iceland, and Scandinavia, as well as sub-Antarctic islands. Why are tundras so cold? The temperatures are so cold that there is a layer of permanently frozen ground […]
How can you tell if an egg has been fertilized?
How can you tell if an egg has been fertilized? Some women may notice symptoms as early as 5 DPO, although they won’t know for certain that they are pregnant until much later. Early signs and symptoms include implantation bleeding or cramps, which can occur 5–6 days after the sperm fertilizes the egg. Other early […]
How do children learn observations?
How do children learn observations? Children learn and imitate behaviors by watching and listening to others. This is sometimes called “observational learning,” when children can learn things simply by observing others. Children are learning about the behavioral choices of others and also about the consequences of those behaviors. What are the 3 key concepts of […]
What is the difference between 1s and 2s orbital?
What is the difference between 1s and 2s orbital? 1s orbital is the closest orbital to the nucleus. 2s orbital is the second closest orbital to the nucleus. Energy of 1s orbital is lower than that of 2s orbital. 2s has comparatively higher energy. Does 3s have higher energy than 2s? In hydrogen the energy […]
What does the slope mean on an acceleration time graph?
What does the slope mean on an acceleration time graph? The slope of an acceleration graph represents a quantity called the jerk. The jerk is the rate of change of the acceleration. How do you represent parallel lines? To symbolize parallel lines in geometry, we use two vertical lines (or slightly slanted lines), like this: […]

What are the three regular views?
What are the three regular views? Typically, an orthographic projection drawing consists of three different views: a front view, a top view, and a side view. Occasionally, more views are used for clarity. The side view is usually the right side, but if the left side is used, it is noted in the drawing. Where […]
What happens when you increase Focal Length?
What happens when you increase Focal Length? If you increase the focal length then the size of the image on the film or sensor will increase i.e. the image will be magnified compared to a lens of shorter focal length. The power of a lens is inversely proportional to its focal length, being equal to […]
How does flow rate affect heat transfer?
How does flow rate affect heat transfer? On the other hand, an increase in the heat transfer coefficient is observed if the area is maintained constant. Doubling the mass flow rate will result in a 92% increase in the heat transfer coefficient. However, there is a concomitant increase in the pressure drop, proportional to the […]
Why does Proton move in electric field?
Why does Proton move in electric field? The electric field is directed from a high electric potential to a low electric potential. The electric force acts on the positive charge in the direction of the electric field, therefore, the proton (positive charge) moves from high electric potential to low electric potential. Where does the electric […]
