Is science absolute or relative?

Is science absolute or relative? Scientific knowledge by itself is relative; but science can not be satisfied with its relative status, therefore it aspires to absolute, universal, to overcome its relative nature. This aspiration is expressed in extrapolation. Are theories always true? A theory will always remain a theory; a law will always remain a […]

What is max current?

What is max current? Ampacity is defined as the maximum current, in amperes, that a conductor can carry continuously under the conditions of use without exceeding its temperature rating. Also described as current-carrying capacity. Electric current flowing through them causes voltage drop and power dissipation, which heats conductors. How do you find the maximum and […]

What does 50% lung capacity mean?

What does 50% lung capacity mean? Likewise, if your FEV1 is 50%, your lungs are able to handle only half as much air as they should. If your FEV1 is 33%, your lungs are able to handle even less—only a third as much. The lower your FEV1 percentage, the less air your lungs are able […]

What kind of mixture is salt solution and seawater?

What kind of mixture is salt solution and seawater? The salt water described above is homogeneous because the dissolved salt is evenly distributed throughout the entire salt water sample. Often it is easy to confuse a homogeneous mixture with a pure substance because they are both uniform. The difference is that the composition of the […]

What does the body use first for energy?

What does the body use first for energy? Carbohydrates are used for energy (glucose). Fats are used for energy after they are broken into fatty acids. Protein can also be used for energy, but the first job is to help with making hormones, muscle, and other proteins. Broken down into glucose, used to supply energy […]

What is Joule formula?

What is Joule formula? In equation form: work (joules) = force (newtons) x distance (meters), where a joule is the unit of work, as defined in the following paragraph. In symbols: W = F x d. In practical terms, even a small force can do a lot of work if it is exerted over a […]

Why is it important to have evidence?

Why is it important to have evidence? Evidence is used to back up or refute arguments, and it helps us to make decisions at work. Using evidence allows us to work out what is effective and what is not. Evidence indicates the ideas that are effective and those, which are not meaning that programs are […]
