Explanation:
LD₁ = 10⁵ mm⁻²
LD₂ = 10⁴mm⁻²
V = 1000 mm³
Distance = (LD)(V)
Distance₁ = (10⁵mm⁻²)(1000mm³) = 10×10⁷mm = 10×10⁴m
Distance₂ = (10⁹mm⁻²)(1000mm³) = 1×10¹² mm = 1×10⁹ m
Conversion to miles:
Distance₁ = 10×10⁴ m / 1609m = 62 miles
Distance₂ = 10×10⁹m / 1609 m = 621,504 miles.
A diverging lens is used to permit clear vision of an object placed at infinity. The focal length of the lens is -100 cm.
<h3>What is focal length?</h3>
The focal length is half of the radius of curvature of the focal lens.
By the lens maker formula,
1/f = 1/v +1/u
where, v is the image distance and u is the object distance.
Give, the object is at infinity and the image must form at 100 cm, the the focal length will be
1/f = 1/ -100 + 1/∞
f = -100 cm
The focal length must be -100 cm for the diverging lens.

Answer:
Atoms are made up of even smaller particles called <u>protons,</u><u> </u><u>electrons </u><u>&</u><u> </u><u>neutrons</u><u> </u><u>(</u><u>sub</u><u>-</u><u>atomic </u><u>particles)</u>
4. bc it is softer--made of a different material-- has a weaker reaction force
5. the sand would not leave footprints and would rather act as a whole
6. there is no gravity in outer space-- she can just float back to the spaceship no problem!
