Answer:
most commonly occurs because of the frequent pumping of water from the ground.
Explanation:
Quartz, feldspa, mica, amphibole, pyroxene and olivine
Answer:
As we are converting 220V AC into a 5V DC, first we need a step-down transformer to reduce such high voltage. Here we have used 9-0-9 1A step-down transformer, which convert 220V AC to 9V AC. In transformer there are primary and secondary coils which step up or step down the voltage according to the no of turn in the coils.
Selection of proper transformer is very important. Current rating depends upon the Current requirement of Load circuit (circuit which will use the generate DC). The voltage rating should be more than the required voltage. Means if we need 5V DC, transformer should at least have a rating of 7V, because voltage regulator IC 7805 at least need 2V more i.e. 7V to provide a 5V voltage.
Increasing its velocity will add to the kinetic energy more as the formula for kinetic energy is 0.5*m*v^2. (The speed will be squared making it greater)
Answer:
Sample size determination
Explanation:
Sample size determination is the process of determining the number of observations to be used in a research hypothesis.
The larger the sample size, the more precise and accurate the results of the hypothesis will be. Bearing this in mind, the researcher will prefer to place a greater value on the research project with 10,000 participants.
