To isolate the variable you need to divide 30 by 2/5. This gets p alone, and you should now have 75 = p.
Answer:
240 nm
Explanation:
In the interference in thin films , light reflected from upper surface and light reflected from the lower surface of oil are made to interfere each other to form fringes due to path difference of 2μt .
a ) An additional phase shift of 180 ° occurs on the upper surface because light is going from optically rarer medium to denser medium .
b ) There is no such change on reflection from lower surface as light is going from denser to rarer medium ( air ).
c ) For destructive interference the path difference which is equal to 2 μ t should be equal to n λ where n is any number
So for given condition
2 μ t = n λ
For minimum thickness
2 μ t = λ ( n =1 )
t = λ / 2μ
= 600 x 10⁻⁹ /( 2 x 1.25 )
= 240 nm

Answer:
10 feet.
Explanation:
Conductors are considered outside the building when they installed. The requirement of NEC is above 10 feet for the clearance after the final grade for service conductors and cables where they are connected with the building, above the sidewalks and the to other areas which are accessible to the pedestrians.
The units of pressure are called derived units because it is derived from base unit, which is distance and a derived unit which is force. Force is derived from acceleration, a derived unit as well, and mass, a base unit; which makes it a derived unit.
