Answer:
66.98 db
Explanation:
We know that
L_T= Total signal level in db
n= number of sources
L_S= signal level from signal source.
= 66.98 db
Answer:
t = 103.45 n m
Explanation:
given,
refractive index of cornea = 1.38
refractive index of eye drop = 1.45
wavelength of refractive index = 600 nm
refractive index of eye drop is greater than refractive index of cornea and the air.
Formula used in this case
for constructive interference
At m = 0 for the minimum thickness, so
t = 103.45 n m
the minimum thickness of the film of eyedrops t = 103.45 n m
For this case we have that by definition:
Where,
- <em>m: mass of the object </em>
- <em>a: acceleration of the object </em>
- <em>F: summation of forces </em>
We have then:
Then, by clearing the acceleration we have:
Substituting values we have:
Answer:
The acceleration of the box is equal to:
