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 relationship between buoyancy and volume?
What is the relationship between buoyancy and volume? Compressible objects As a floating object rises or falls, the forces external to it change and, as all objects are compressible to some extent or another, so does the object’s volume. Buoyancy depends on volume and so an object’s buoyancy reduces if it is compressed and increases […]
When would you use cumulative frequency?
When would you use cumulative frequency? Cumulative frequency is used to determine the number of observations that lie above (or below) a particular value in a data set. The last value will always be equal to the total for all observations, since all frequencies will already have been added to the previous total. What is […]
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 […]
What are 2 main types of scientific inquiry?
What are 2 main types of scientific inquiry? The word Science is derived from Latin and means “to know” Inquiry is the search for information and explanation. There are two main types of scientific inquiry: discovery science and hypothesis-based science. What is the scientific method of discovery? The process in the scientific method involves making […]
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 […]
