<u>Vitreous humor</u>
Retina
Convex lens.
The figure (examples ) of the question is attached below.
Answer: The answer is prism.
Explanation:
When a ray of white light passes through the prism it separates into many colors or different wavelength of light is seen.
This phenomenon is known as diffraction .In the visible wavelengths of the electromagnetic spectrum, red, is diffracted most and violet is diffracted lowest due to shortest wavelength.
It appears like a rainbow of 7 colors because it is white light that diffracts into 7 colors after passing a prism.
Answer:
The speed at the end of the track = 27 m/s
The acceleration = 1.2 m/s²
Please find the Δx vs Δt, v vs Δt, a vs Δt
Explanation:
We have;
x = u·t + 1/2·a·t²
Where;
x = The distance = 300 m
u = The initial velocity = 0 m/s (Ball at rest)
t = The time taken = 22.4 s
Therefore;
300 = 0 + 1/2×a×22.4²
a = 2×300/22.4² = 1.19579 ≈ 1.2 m/s²
v = u + a×t
∴ v = 0 + 1.2 × 22.4 = 26.88 ≈ 27 m/s
Part of the table of values is as follows;
t, x, v
0, 0, 0
0.4, 0.095663, 0.478316
0.8, 0.382653, 0.956632
1.2, 0.860969, 1.434948
1.6, 1.530611, 1.913264
2, 2.39158, 2.39158
2.4, 3.443875, 2.869896
2.8, 4.687497, 3.348212
3.2, 6.122445, 3.826528
3.6, 7.748719, 4.304844
I believe the answer is C, and not D because B is incorrect. The water and wind erosion smoothen the rock creating a mushroom shape.
