Answer:
- 103.7
Step-by-step explanation:
Given:
Focal length of the eyepiece, f = 2.0 cm
Focal length of the objective lens, f' = 0.50 cm
Separation for minimum eyestrain = 6,0 cm
Image distance, v = - 25 cm
Now, from the lens formula,
here, u is the object distance
on substituting the respective values, we get
or
u = 1.852 cm
also, the separation is adjusted for minimum eyestrain,
therefore, image distance for the objective lens, v' = 6 - 1.852 = 4.148 cm
Now, for the objective lens
using the lens formula, we get
Here, u' is the distance between the physical object and objective lens
or
u' = 0.568 cm
Thus,
Magnification, m =
or
m =
or
m = - 103.7
Answer:
0.923
Step-by-step explanation:
There are 13 total marbles. (12 Purple Marbles + One Blue Marble)
The total events are 13 and the number of preferred events is 12.
≈ 0.923
So there should be a 0.923 chance that a purple marble is picked.
