Violet light frequency is 7.5 x 10^14 hertz. As according to the relation between light's speed, frequency and wavelength, λ = c / f, the wavelength of violet light can be found to be approximately 400 nanometers.
The relationship between frequency (f), wavelength (λ), and the speed of light (c) is expressed by the equation c = fλ. Given the speed of light c is approximately 3.00 × 10⁸ meters per second (m/s) and the frequency of violet light f is given as 7.5 × 10¹⁴ hertz (Hz), we can solve for wavelength λ. Rearranging the equation gives us λ = c / f. Substituting the given values we find that λ = (3.00 × 10⁸ m/s) / (7.5 × 10¹⁴ Hz), which computes to approximately 400 nanometers (nm). This result corroborates that violet light is typically within the range of 380 - 450 nm, thus confirming its position at the high-frequency, short-wavelength end of the visible light spectrum.

B. L = W; F = D
C. L = W = F = D
D. L = W; F > D
Answer:
(B) L=W; F=D
Explanation:
Since the airplane's velocity is constant, the airplane is not accelerating in any direction. In absence of acceleration, all forces acting on the plane are balanced so that the net forces in the horizontal and the vertical directions are zero. Given the drawing, this implies that
Forward force = Drag force (F=D)
Weight = Lift (W=L)
which corresponds to option (B)
(it is not C because nothing in the text says that the vertical and horizontal components have to have same magnitude)
The relationship between the magnitudes of the forces is that lift force is equal to weight force, and drag force is equal to thrust force.
In this scenario, the airplane is flying at a constant velocity, which means that its acceleration is zero. According to Newton's first law of motion, if an object is moving with a constant velocity, the net force acting on it is zero.
Therefore, the relationship between the magnitudes of the four forces shown in the diagram is that the lift force (L) is equal to the weight force (W), and the drag force (D) is equal to the thrust force (F).
So, the correct answer is C. L = W = F = D.

Explanation:
In liquids, force of attraction between the molecules is less as compared to solids but force of attraction between the molecules is more strong as compared to gases.
Also, liquids do not have any definite shape and they acquire the shape or container or vessel in which they are placed.
Therefore, when a liquid is simply transferred from one container to another container then its volume remains the same.
B altered water flow
C deforestation of woodlands
D decreased water quality
Answer:
Option (C)
Explanation:
In order to set up urbanization in a selected area, initially, a large number of trees are being cut down. This process is commonly known as deforestation.
The deforestation process has various impacts on the environment and the climatic condition at various places. Extensive cutting down of trees leads to the occurrence of rapid soil erosion, where the materials from the topsoil are entirely carried away by wind and water. Due to this, there occurs a high absorption of incoming solar energy that increases the temperature of that area.
In addition to this, trees are the main source from which the oxygen is provided. The absence of trees also leads to an increase in the amount of carbon dioxide because the carbon dioxide will not be absorbed by the trees and in return, it won't be able to provide us oxygen. Due to this, the amount of carbon dioxide also increases.
Thus, the above changes are caused due to the deforestation of woodlands.
Hence, the correct answer is option (C).
