Answer:
a) P = 149140[w]; b) 1491400[J]; c) v = 63.06[m/s]
Explanation:
As the solution to the problem indicates, we must convert the power unit from horsepower to kilowatts.
P = 200 [hp]
Now the power definition is known as the amount of work done in a given time
P = w / t
where:
w = work [J]
t = time [s]
We have the time, and the power therefore we can calculate the work done.
w = P * t
w = 149140 * 10 = 1491400 [J]
And finally, we can calculate the velocity using, the expression for kinetic energy
The key to solving this problem is to recognize that work equals kinetic energy
Answer:
The minimum thickness of the oil is 77.55 nm
Explanation:
Given:
Refractive index of oil
Refractive index of water
Wavelength of light m
From the equation of thin film interference,
The minimum thickness is given by,
Where ,
thickness
Here we have to find minimum thickness so we use
m
nm
Therefore, the minimum thickness of the oil is 77.55 nm
