Answer:
the beetle's actual distance beneath the surface, d = 3.2 cm
Explanation:
The refractive index for the plastic is about 1.60
For overhead viewing, the expression for refractive index is
n = actual depth / apparent depth
Rearrange for actual depth
actual depth d = n x apparent depth
d = 1.60 x 2.0 cm
d = 3.2 cm
The part is the ear canal
Well, i think there are more than one answers for this question. What influence whether or not bricks slide down the bed of the dump trucks will depends on :
- The mass of the Bricks
- The angle of the Bed
- The coefficient of static friction between the bricks and the bed
- the coefficient of kinetic friction between the bricks and the bed
hope this helps
Answer:
A: They produce a real image.
Explanation:
The images formed on the retina of the eye for a normal visibility must always be real.
Only a real image can be physically projected on any physical object whereas the virtual images are visible due to reflections.
- The nearsightedness is corrected with the help of a concave lens since it is the condition of the eye lens remaining thick and curved to converge the rays entering the eyes after a shorter distance which results in their image formation even before the retinal surface so to initially diverge them a bit so that they converge on the retinal surface and form the image there we use concave lens. Vice-versa of the above justification in the case of farsightedness.
