Answer:
Explained
Explanation:
A model is practical representation of reality with help of various tools called model. It is more purposeful, appealing and provide greater understanding of the specific phenomenon called modeling.
Theory on the other hand are set of written statement which is more generalized and aimed to explain the phenomenon. Theory is developed through the process of abstraction, experimentation, and deduction.
A model is often is used to describe an application of a theory for a specific case.
Since you are looking at a right fringe, the answer is all
the time a multiple of the wavelength for the reason that the light makes
constructive intrusion. If you are looking at the center (zeroth) fringe, the
difference is (450)(0) = 0. For the first maximum, the difference is 450 nm.
For the second, it is 450 x 2 = 900 nm. Basically, for the nth maxima, the
difference is 450n.
Answer:
As the earth spins on its axis, producing night and day, it also moves about the sun in an elliptical (elongated circle) orbit that requires about 365 1/4 days to complete. The earth's spin axis is tilted with respect to its orbital plane. This is what causes the seasons.
Explanation:
To solve this problem it is necessary to apply the concepts related to Ohm's Law to find the voltage in the case of direct current. While for the Alternate current we use the concept of RMS voltage.
PART A) In the case of DC we have to,
V=IR
Where,
I = Current
R = Resistance
Where the current is 60mA y the resistance is
, then the potential would be


In the case of DC we have that the current and the RMS voltage is,



The potential in AC then is,
