What is Psi²? psi represents the amplitude of the electron wave. It is commonly called wave function. It is a mathematical function and has no physical meaning by itself. Magnitude of psi square has the physical meaning as it determines the probability of density of finding the electron at that point. What is a physical […]
Why is the fresh water important?
Why is the fresh water important? Freshwater is essential for our planet. Freshwater environments include rivers, lakes, wetlands, streams and underground aquifers. They store and clean the water that’s crucial for people and wildlife. Healthy freshwater environments supply water for drinking, growing crops, manufacturing, energy and transport. What would happen without freshwater? Due to their […]
Why are plants green?
Why are plants green? So, plants and their leaves look green because the “special pair” of chlorophyll molecules uses the red end of the visible light spectrum to power reactions inside each cell. The unused green light is reflected from the leaf and we see that light. Are plants actually green? Green plants are green […]
What does SSE wind mean?
What does SSE wind mean? South-Southeast What does it mean when it says wind is NW? Mike Moss: The term “wind direction” is defined as the direction from which the wind is blowing. The result is that an east wind, for example, would cause a balloon to follow a westerly bearing, and regarding your specific […]

What is a hypothesis test in statistics?
What is a hypothesis test in statistics? Hypothesis testing is an act in statistics whereby an analyst tests an assumption regarding a population parameter. Hypothesis testing is used to assess the plausibility of a hypothesis by using sample data. Such data may come from a larger population, or from a data-generating process. What is null […]
What is the formula for tangent?
What is the formula for tangent? The tangent function, along with sine and cosine, is one of the three most common trigonometric functions. In any right triangle, the tangent of an angle is the length of the opposite side (O) divided by the length of the adjacent side (A). In a formula, it is written […]
Does boiling water go above 212 degrees?
Does boiling water go above 212 degrees? Above 212°F at standard pressure, liquid water is unstable. in it, this boiling process doesn’t happen until the temperature is significantly above 212°F, so you can temporarily have liquid water (called ‘superheated’) above that boiling point. Is steaming faster than boiling? Steaming makes your vegetables taste better. Steaming […]
Why is it important to know the structure of an atom?
Why is it important to know the structure of an atom? 4.4 Structure of the atom (ESAAZ) As a result of the work done by previous scientists on atomic models, scientists now have a good idea of what an atom looks like. This knowledge is important because it helps us to understand why materials have […]
What type of heat transfer is responsible for toasting your bread in a toaster?
What type of heat transfer is responsible for toasting your bread in a toaster? Convection Is Toast making radiation? Toasting is done by radiation, which can supply the higher temperatures required for both caramelization and the Malliard browning reactions. It can be both the Maillard reactions and caramelization, depending upon how dark your toast is […]
