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 […]
Which among Following is a noble gas?
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 […]
Is upward positive or negative?
Is upward positive or negative? We consider the direction of gravity as positive and the upward direction as negative. Displacement is positive below the starting point and negative above. Velocity is positive in a downward direction and negative when going upward. For horizontal motion, right is positive and left is negative. Is lift an upward […]
What is the heaviest element that really large stars can make by fusion?
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 can we use iodine to test for?
What can we use iodine to test for? In the presence of starch, iodine turns a blue/black colour. It is possible to distinguish starch from glucose (and other carbohydrates) using this iodine solution test. For example, if iodine is added to a peeled potato then it will turn black. Benedict’s reagent can be used to […]
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 […]
What are the 5 functions of leaves?
What are the 5 functions of leaves? As one of the most important constituents of plants, leaves have several essential functions: Photosynthesis. Transpiration. Guttation. Storage. Defense. Conifer Leaf. Microphyll Leaf. Megaphyll Leaf. What are two function of leaves? Its main functions are photosynthesis and gas exchange. A leaf is often flat, so it absorbs the […]
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. […]
