Answer:
θ = 36.2º
Explanation:
When light passes through a polarizer it becomes polarized and if it then passes through a second polarizer, it must comply with Malus's law
I = I₀ cos² tea
The non-polarized light between the first polarized of this leaves half the intensity, with vertical polarization
I₁ = I₀ / 2
I₁ = 845/2
I₁ = 422.5 W / m²
In this case, the incident light in the second polarizer has an intensity of I₁ = 422.5 W / m² and the light that passes through the polarizer has a value of
I = 275 W / m
²
Cos² θ = I / I₁
Cos θ = √ I / I₁
Cos θ = √ (275 / 422.5)
Cos θ = 0.80678
θ = cos⁻¹ 0.80678
θ = 36.2º
This is the angle between the two polarizers
Answer: Option (B)
Explanation: A stream transports its materials in different ways-
- <u>Dissolved load-</u> Here, the materials gets dissolved when mixed with water and flows along with the stream.
- <u>Suspended load</u>- Here, the materials are not fully dissolved in the water but they can be carried from one place to another in suspension mode, by the river.
- <u>Bed load-</u> Bed load are transported in three different ways such as-
- Sliding- here, the materials slides down along a curved surface under the water and carried away.
- Rolling- here, the materials are solid and due to force exerted by water, it can roll and move to distant places.
- Saltation- here, the materials are carried away in a series of jumps.
Thus, the most appropriate answer is option (B) i.e bedload.
Answer:
I would guess they'd probably be in an area they feel is habitatible.
Hi there, the correct answer is C. Reactivity. I know this is the correct answer because I took this quiz recently. Color, boiling point, and density are all examples of physical properties.
