Can I reverse a transformer? When a transformer is reverse fed, the taps move to the output side and so their operation is reversed. For reverse fed applications, raising the taps will increase output voltage and lowering the taps will lower output voltage. What is the difference between step up transformer and step down transformer? […]

What are the stages of experimental research design?
What are the stages of experimental research design? The types of experimental research design are determined by the way the researcher assigns subjects to different conditions and groups. They are of 3 types, namely; pre-experimental, quasi-experimental, and true experimental research. What is the treatment in this experiment? and the “treatment” is the variable you are […]
Was all land once connected?
Was all land once connected? The word Pangaea means “All Lands”, this describes the way all the continents were joined up together. Pangea existed 240 million years ago and about 200 millions years ago it began to break apart. Over millions of years these pieces came to be the continents as we know them today. […]
How do you identify bullish momentum?
How do you identify bullish momentum? Momentum is used by investors to trade stocks in an uptrend by going long (or buying shares) and going short (or selling shares) in a downtrend. In other words, a stock can be exhibit bullish momentum, meaning the price is rising, or bearish momentum where the price is steadily […]
How many electrons does sodium ion have?
How many electrons does sodium ion have? 10 electrons Why is the sodium ion represented as Na+? Neutral sodium atom (Na) becomes sodium cation (Na+) by releasing an electron. positive charge on the sodium cation is balanced by the negative charge on the chloride, so the ionic compound is neutral. What is the difference between […]
What are the 2 main types of telescopes?
What are the 2 main types of telescopes? There are two basic types of telescopes, refractors and reflectors. The part of the telescope that gathers the light, called the objective, determines the type of telescope. A refractor telescope uses a glass lens as its objective. Who is the father of astronomy? Copernicus What kind of […]
What is caused by the collisions of gas particles with their container?
What is caused by the collisions of gas particles with their container? The collision of molecules with their container walls results in a momentum transfer (impulse) from molecules to the walls (Figure 10.7. 2). Figure 10.7. 2: Momentum transfer (impulse) from a molecule to the container wall as it bounces off the wall. How do […]
What is a isokinetic muscle contraction?
What is a isokinetic muscle contraction? An isokinetic muscle contraction occurs when the velocity of the muscle contraction remains constant while the length of the muscle changes. In an isokinetic concentric contraction, the muscle shortens while under load. In an isokinetic eccentric contraction, the muscle lengthens while under load. Is swimming isokinetic? The water provides […]
