Answer:
The power of the corrective lenses is 3.162 D.
Explanation:
Given that,
Object distance = 70 cm
Image distance = 62 cm
Distance between eyes and glasses = 2.5 cm
Eyeglasses made of diverging corrective lenses can help her to see the apple clearly
So now ,
Object distance from glass =70-2.5 = 67.5 cm
Image distance from glass = 62-2.5 = 59.5 cm
We need to calculate the focal length
Using formula for focal length



We need to calculate the power of lens
Using formula of power



Negative sign shows the lens is diverging.
Hence, The power of the corrective lenses is 3.162 D.
Answer:
When something is transparent, it means that it allows light to pass through or is see-through . For example:
1) glass
2) air
3) some plastics
Answer:
yes it doesn't matter
Explanation:
it doesn't matter because troughs and crests are the same and either can be used
GPE= weight•height= 15 N• 0.22meter= 3.3 Joules
