What is the importance of your choice of units in expressing the value of the ideal gas law constant?
If any other units are used, the value will be different. --Depending on the units you chose the value of the constant differs
What does the term true value mean in science?
In classical physics it was thought that every physical quantity has a "true value" that can be only estimated through measurements due to measurements errors. The way of getting nearer and nearer to this "true value" was thought on one side to increase the measurement accuracy, on the other side to increase the number of measurements so to use statistical methods to attenuate the effect of random errors. The situation is completely changed with quantum mechanics. In quantum mechanics an "intrinsic" inaccuracy affects all the physical quantities, independently of measurement errors. Thus physical quantities would be random variables even if measured by an ideal instrument with no bias and no random error. Thus, in modern physics no physical quantity "true value" exists. The only exception is the very rare and particular case of quantum self-state of a certain variable, where that variable only ha a precise value (but not the other variables of the problem !). However this is an extreme and unpractical case, and it seems to me not the case of going in deep in its explanation here.

How does a measurement differ from a number?
There are no standards of measurements. A measurement is an approximation or an estimation of an exact value. A number is an exact value such as one pencil or two cars.
What is the ideal value of vswr?
The ideal value of VSWR is 1 (one), which means that full power which has been arrived to the antenna is emitted to the air. In reality it is always more than 1, which means that some part of power reflected from antenna to the transmission line.
If some measurements agree closely with each other but differ widely from the actual value these measurements are?
precise but unreliable.
Why you consider only rms value of voltages and currents in ac circuits?
RMS is most commonly used measurement for AC because the power calculated from it matches the power calculated from DC and is the true power, if there is no phase shift. Its not the only measurement, just the most generally useful. Other measurements are still useful for purposes other than power calculation.
What is a sample statistics?
It is a value calculated from the sample values only.It is a value calculated from the sample values only.It is a value calculated from the sample values only.It is a value calculated from the sample values only.
How can estimation help to decide if answer to multiplication problem makes sense?
If the estimated value is very different from the calculated value then the answer is wrong. Unfortunately, it does not work the other way. An estimate can be close to the calculated value but the answer can still be wrong.
What advances did Archimedes make?
Archimedes made a variety of advances including volume and buoyancy measurements along with mathematics that define the size of a cylinder using a sphere. He also helped to make a lever more useful in farming.
What is derived attribute?
Attribute whose value may be calculated (derived) from other Attribute
What The closeness of a measurements to it value is a measure of it what?
accuracy

An ideal voltage source will charge an ideal capacitor?
An ideal capacitor is characterized by a single constant value for its capacitance.
What is Ideal Jawa's motto?
The motto of Ideal Jawa is 'Forever bike , Forever value'.
What do the digits refer to in a digital multimeter?
value of measurements
What is when measurements are close to the accepted value?
The term is accuracy
