Environmental Protection Agency enforced regulations primarily aim to reduce environmental pesticide contamination.
<h3>What is a Pesticide?</h3>
This refers to a chemical which is used to control pests and examples include insecticide, nematicide etc.
Environmental Protection Agency is government owned and ensures strict enforcement of regulations to reduce environmental pesticide contamination which could lead to death of beneficial organisms.

Answer:
120 mL = 120 cm^3
Explanation:
1 mL is <em>equal</em> to exactly 1 cubic centimeter, so 120 mL = 120 cm^3
Answer:
I. light house 1 will be warmer during the day ii. light house 2 will be warmer at night.
Explanation:
Because the land conducts heat better than water the light house farthest away from the water will get hotter during as the ground will heat up faster than the water. But this also means that the ground will lose heat faster at night where the water won't making the light house closest to the water hotter at night.

It can be seen by the eye

Took the test
Answer:
λ = 6.61 x 10⁻⁷ m = 661 nm
Explanation:
From the Young's Double Slit experiment, the the spacing between adjacent bright or dark fringes is given by the following formula:
Δx = λL/d
where,
Δx = fringe spacing = 2.86 mm = 2.86 x ⁻³ m
L = Distance between slits and screen = 2.12 m
d = slit separation = 0.49 mm = 0.49 x 10⁻³ m
λ = wavelength of light = ?
Therefore,
2.86 x 10⁻³ m = λ(2.12 m)/(0.49 x 10⁻³ m)
(2.86 x 10⁻³ m)(0.49 x 10⁻³ m)/(2.12 m) = λ
<u>λ = 6.61 x 10⁻⁷ m = 661 nm</u>
