Is beating of drum periodic motion?
Is beating of drum periodic motion? The beating of the drum occurs at defined period. So, it is a periodic motion. Which is periodic wind? Periodic winds blow at regular intervals or in regular cycles. They are winds that result from localised differences in pressure and temperature. For example, land and sea breezes and the […]
What is PHI in RLC circuit?
What is PHI in RLC circuit? Conventionally, the phase angle between the voltage and current is symbolized by the Greek letter phi. The tangent of this angle is given by: tan (phi) = (XL-Xc)/R. The power dissipated in an RLC circuit is given by P = VI cos (phi). What is Susceptance formula? What is […]
What is the heaviest element that really large stars can make by fusion?
Does pineapple lower blood pressure?
Does pineapple lower blood pressure? Pineapple Juice: Pineapple juice reduces hypertension due to the adequate presence of potassium and a lesser amount of sodium. (A cup of pineapple juice contains about 1 milligram of sodium and 195 milligrams of potassium. Why would your blood pressure be high and low? In other cases, some uncontrollable factors […]
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 […]
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. […]
