Answer:
a) p = 95.66 cm, b) p = 93.13 cm
Explanation:
For this problem we use the constructor equation
where f is the focal length, p and q are the distances to the object and the image, respectively
the power of the lens is
P = 1 / f
f = 1 / P
f = 1 / 2.25
f = 0.4444 m
the distance to the object is
the distance to the image is
q = 85 -2
q = 83 cm
we must have all the magnitudes in the same units
f = 0.4444 m = 44.44 cm
we calculate
1 / p = 0.010454
p = 95.66 cm
b) if they were contact lenses
q = 85 cm
1 / p = 0.107375
p = 93.13 cm
Answer:
Explanation:
Given:
- refractive index of the glass plate,
- thickness of the glass plate,
- wavelength of the source light,
<u>We know that the refractive index of a medium is given as:</u>
Hence the no. of wavelengths in the glass:
Potential energy is what something has energy of staying still. if a car was the the top of a hill that’s where it has the most potential. kinetic energy is energy in motion. as that car on the hill starts to roll down, the potential of it lowers as the kinetic raises
We are ask to know where is the location of the coal bed, in
this given sentence when you need to analyze every words just to know where is
the coal bed located.
To my understanding the coal bed is located just above the
highest piece of sandstone seen in the soil.
