What are two types of electric current? Current electricity is a constant flow of electrons. There are two kinds of current electricity: direct current (DC) and alternating current (AC). With direct current, electrons move in one direction. Batteries produce direct current. Is gold good conductor? Gold is used as a contact metal in the electronics […]

Which is called the living part of a cell? Protoplasm (/prəʊtə(ʊ)ˌplaz(ə)m/, plural protoplasms) is the living part of a cell that is surrounded by a plasma membrane. In some definitions, it is a general term for the cytoplasm (e.g., Mohl, 1846), but for others, it also includes the nucleoplasm (e.g., Strasburger, 1882). Is a living […]

What is Mew M? The micrometre (international spelling as used by the International Bureau of Weights and Measures; SI symbol: μm) or micrometer (American spelling), also commonly known as a micron, is an SI derived unit of length equalling 1×10−6 metre (SI standard prefix “micro-” = 10−6); that is, one millionth of a metre (or […]

The goal of Gestalt therapy is to teach people to become aware of significant sensations within themselves and their environment so that they respond fully and reasonably […]

Is there a ball that can bounce forever? The law of conservation of energy implies that a bouncing ball will bounce forever. Of course, it does not. When you drop it on the floor, it changes some of its energy into other forms, such as heat, each time it hits the floor. What are bouncy […]

How do you sink wood in water? To saturate your wood you can soak it in water for a while. Keep some kind of weight on the wood to keep the entire piece submerged. The soaking will also help to leach tannins out of the wood which can discolour the water and can be harmful […]

What do you mean by eigen value and eigen function? Such an equation, where the operator, operating on a function, produces a constant times the function, is called an eigenvalue equation. The function is called an eigenfunction, and the resulting numerical value is called the eigenvalue. Eigen here is the German word meaning self or […]

What are two plant processes? Fundamental processes such as photosynthesis, respiration, plant nutrition, plant hormone functions, tropisms, nastic movements, photoperiodism, photomorphogenesis, circadian rhythms, environmental stress physiology, seed germination, dormancy and stomata function and transpiration, both parts of plant water relations. What occurs only in plants? Photosynthesis occurs only in plants, algae, and some bacteria. How […]

What are the dimensions of the quantity? The dimension of a physical quantity is defined as the powers to which the fundamental quantities are raised in order to represent that quantity. The seven fundamental quantities are enclosed in square brackets [ ] to represent its dimensions. What are the dimensions of the quantity 1? The […]

Why do meteorologists use station models quizlet? Meteorologists created the station model to fit a number of weather elements into a small space on weather maps. This allows map users to analyze patterns in atmospheric pressure, temperature, wind speed & direction, cloud cover, precipitation, etc. How is the Doppler effect used to predict weather? Answer: […]
