What affects the jet stream?
What affects the jet stream? The factors that influence the flow of the jet stream are the landmasses and the Coriolis effect. Landmasses interrupt the flow of the jet stream through friction and temperature differences, whilst the spinning nature of the earth accentuates these changes. What happens if the AMOC stops? An AMOC shutdown may […]
Why gold leaves are used in Electroscope?
Why gold leaves are used in Electroscope? A gold-leaf type electroscope is a device used to detect the presence of electric charge on a body and its relative amount. They also capture charge leaking through the air that could accumulate on the glass walls, and increase the sensitivity of the instrument. What happened when you […]

What is the principle of fluid displacement in biology?
What is the principle of fluid displacement in biology? What is Archimedes’ principle? A body at rest in a fluid is acted upon by a force pushing upward called the buoyant force, which is equal to the weight of the fluid that the body displaces. If the body is completely submerged, the volume of fluid […]
What is the first basic principle of light?
What is the first basic principle of light? The First Basic Principle of Light ‘Light is a form of energy’ When light reaches a surface, it can be absorbed and transformed into other types of energy. What are the 2 special properties of light? The primary properties of visible light are intensity, propagation-direction, frequency or […]
What is the heaviest element that really large stars can make by fusion?
Why does mass not affect pendulum period?
Why does mass not affect pendulum period? The mass of a pendulum’s bob does not affect the period. As mass increases, so does the force on the pendulum, but acceleration remains the same. (It is due to the effect of gravity.) Because acceleration remains the same, so does the time over which the acceleration occurs. […]
Does multiplication always come first?
Does multiplication always come first? Order of operations tells you to perform multiplication and division first, working from left to right, before doing addition and subtraction. Continue to perform multiplication and division from left to right. Next, add and subtract from left to right. Multiply first. Do you multiply first if no brackets? Just follow […]
Which compound is the least soluble in water?
Which compound is the least soluble in water? alkane How do you know if a organic compound is water soluble? Small, polar organic compounds such as alcohols, aldehydes, ketones, amines, carboxylic acids, and a few phenols are soluble in water. Water-soluble compounds are tested with pH paper to see if they are acidic or basic. […]
