Do experimental measurements give the true value of physical quantity?
No because there are always experimental errors, instrument limitations, and deviations in measurements. This is called the uncertainty. Experimental values do not give true values but rather a value with an uncertainty.
How does a aircraft tachometer work?
It works the same way a car tach works. It measures engine revolutions electrically from the coil/distributor or from a crankshaft sensor that is usually magnetic. On jet engines it is measured from the constant speed drive and is measured in percent of total power available rather than rpms.
What is the importance of computational physics?
That rather puts the cart before the horse. The computer is important, but only as a tool to make possible extremely complex predictive and analytical models and calculations. So the Physics is the important bit. The computer is a research tool.
How can you avoid parallax errors when measuring a length with a meter rule?
Place the rule directly on the surface being measured, rather than at a distance from it.
When to use law of momentum to find velocity rather than law of conservation of energy?
While energy is ALWAYS conserved, this isn't always useful for calculations, since MECHANICAL ENERGY - the energy that can be easily calculated - is NOT always conserved. On the other hand, momentum is always conserved, whether a collision is elastic or inelastic. (In an elastic collision, energy is also conserved.) Thus, conservation of momentum is often more useful for calculations involving collisions.
Where the ALU is used?
A; In a computer if the need is for number crunching or rather calculations
What is an experimental control?
A group of experimental subjects that is not exposed to a chemical or treatment being investigated so that it can be compared with experimental groups that are exposed to the chemical or treatment. cw: An experimental control may be the control group. In general, the experimental control is something that allows you to say that the treatment effects on the experimental group are due to the treatments, rather than anything else.

Why do CDMA phones get heated up while talking?
Calculations!!! CDMA Does lot more calculations than CDMA and Chip gets heated. its GSM rather
Some scientific data are obtained through observation rather than experimental results?
True
Father of experimental science?
Galileo galilei was and is sometimes referred to as "the father of experimental science." Galileo didn't take much on faith, rather, he tested his ideas through experiments and expressed them in mathematical form.
What is the meaning of experiment Probability?
The experimental probability of an event is the probability that is calculated from repeated trials rather than from theoretical models.
Who was the father of experimental science and mathematician?
Galileo Galilei was and is sometimes referred to as "the father of experimental science." Galileo didn't take much on faith, rather, he tested his ideas through experiments and expressed them in mathematical form.
Which capital budgeting method uses accrual accounting rather than net cash flowsl as a basis for calculations?
apr
Continuous random variables are obtained from data that can be measured rather than counted?
true
What is the mathematical formula for calculating temperature?
Temperature is usually measured, rather than calculated.
What is an example of quantitative measurement?
data or information that is measured numerically rather than qualitatively.
