Answer:
149.8Hz
Explanation:
V=I.(XL).........{1}
where (XL) is inductive reactance
(XL) =2πfL......... {2}
V= 41.5, l= 4.5, L= 9.8* 10^-³
take π to be 3.14
(XL) = V/I
= 41.5/4.5
= 9.22
f = (XL) /2πL
= 9.22* 10^³/6.28* 9.8
=149.8
Validity concludes the whole experimental values and concepts which makes that whether the results which are obtained meet all of the requirements of the scientific research method.
On which factors the validity of an experiment depends?
There are five components which are used in experiment: observations, questions, hypothesis, methods and results. The scientific method procedure is not only ensures that the same experiment can be repeated by other researchers, but this experiment is accepted. For example, there must have been arrange in a random way of the sample groups and proper work and care shows and the experiment is succeed.
So we can conclude that: Validity concludes the whole experimental values and concepts which makes that whether the results which are obtained meet all of the requirements of the scientific research method.

A system is contained by its boundary; therefore, the size of a system is limited by its boundary.
Well to find the total miles what I would do is 18 x 22 which would equal 396 so the answer would be: You can go 396mi with a car that gets 22 mpg* and holds 18 gallons
*Mpg=Miles per gallon
Answer:
The density is: 
Explanation:
Recall that density is defined as the quotient of the object's mass divided by volume. So, we calculate the volume of the 3 cm side cube:
then the density becomes:
