Why are the M and C terminals of a watt meter short circuited?
In a watt-meter there are four terminals:
M,L which are the current coils and
C,V which are called as pressure coils . .
To measure the current the measuring instrument should be placed in series with the load but in case of voltage, the instrument should be connected in parallel to the load . .
therefore M from the current coil and C from the pressure coil are can be short-circuited to measure the power of the given circuit.

Explain the difference between a hypothesis and a theory?
A very complicated question but to pare it down:
An hypothesis is a preliminary answer to a scientific question but is one which needs testing.
A theory is an hypothesis that has withstood numerous tests and has not failed.
Perfume is made up of alcohol, water and perfume oil (fragrance). Alcohol acts as a base that mixes the oil, and also acts as a volatile ingredient to help the perfume molecules evaporate and spread in the air. Perfume fragrances are particularly detectable by the human scent receptors, even in very minute concentrations.
The term bioethical describes questions about what people should do with knowledge in biology that cannot be answered using the scientific method. The scientific method is a method of procedure that consists of observation, measurement, and experiment.
Absolutely, the scientific method is the very backbone of experimenting and only through experimenting can scientists make discoveries. The scientific method is necessary to ensure validity, and reliability, without it we can't trust the results to be accurate or reliable.
What are the four problemsolving steps in the correct order?
1-Understand the problem
2-Gather your resources.
3-Come to an answer.
4-Check your answer and present the solution.
.
When you add so much solute that no more dissolves what do you have?
A saturated solution is made when you have added so much solute that no more dissolves. The amount of solute needed to make a saturated solution will change with the temperature of the solution.
Can sound travel through oxygen?
Yes, sound can travel through oxygen. Sound waves are able to travel through any medium that has molecules, including gases like oxygen. However, sound travels faster through solids and liquids compared to gases.
" Biotic" Means Living, Therefore, The Question(?) Is Asking :
You Welcome :)
How did the scientific method change the way scientists approached problems?
Unlike most earlier approaches, it did not rely on authorities like Aristolte or Ptolemy or even the Bible. It depended instead upon observation and experimentation.

this supercontinent is called PANGEA. it is the greek word for "all lands".
A pholem is a tube that is made from living cells. Their function is to transport the glucose that is produced by photosysnthesis in the leaves to where it is needed. Pholem cells along with xylem cells produce vascular bundles.
What is the effect of temperature on rates of reactions?
Typically heat will speed up a chemical reaction because it causes the actual atoms to move quicker and collide with each other causing a chemical reaction. For example a redox reaction where a electron is passed between atoms.
What factors affect the speed of a computer?
Many things determine a computer's speed. Just about everything inside of your computer (hardware & software) can make a difference. The first and probably most common measurement of speed is the clock-speed of your main CPU. This is measured in Megahertz or Mhz. Quite simply the more the better, and 1000s of Megahertz are measure in Gigahertz or GHz. So 2000 Mhz = 2GHz. Another new development in computer technology has also allowed for multiple cores in a single CPU. This can allow multiple independent processing cores to exist on a single board. With this technology your CPU can processes simultaneous tasks without over-taxing a single CPU. Many other things must be taken into consideration as well though, how much RAM your computer has, how fast your hard drive spins, the size of your hard-drive's main platter, what operating system you have, how many other devices are connected to the computer, how much software you have loaded on to it, etc. The list can literally include everything inside of a computer. A better way to examine the question would be to figure out what task you want to speed up. This could include how fast your computer turns on, how fast it can process multi-media types of data (audio/video), or server level computing for applications, services, and user management. Different hardware and software components affect speed in different ways and sometimes optimizing a computer to perform one specific task can yield better performance results.
Why is some diesel fuel dyed pink?
Diesel is two different colors that include light yellow and blue. They are different colors so that people can distinguish between the two in order to know what is best for their vehicle. Light yellow is for vehicles that run on the highway while light blue is for marine and agriculture vehicles.
Why is observation important in the scientific method?
Science is defined as the medium in which the conscious mind can interpret and observe the universe around which it exists. The mind always tries to fix patterns in which it can rely on to explain the behavior of or reason for an event or a pure existing idea. Observation in the mere interpretation of the event, which is what the study of science is all about initially. We observe to understand, and when we understand we observe again to check our understanding. When our understanding proves correct, we conclude a theory, and that is what science is. Observation is the heart of discovery.
In the science fair project do you have to have a hypothesis?
It could be about 2 to 3 sentences,but it shouldn't be to long.
What are the seven soldering steps in order?
The seven soldering steps are first you need to fit everything into one place then start to kill them
How do you write a hypothesis for a science project?
A hypothesis for a science project is any idea that you want to prove or disprove. Some examples are that chicken eggs will not float if they are hard boiled or that hot air does not always rise.
areas of rising air and low pressure. When air rises it cools, and the moisture it contains condenses out as clouds, which eventually produce precipitation.
