How food chain is disrupted through water pollution?

Physics
1 answer:
Liula [17]3 years ago
4 0
Water pollution offsets the nutrient balance in the water, disturbing microscopic life as well as aquatic plant life. These organisms are at the bottom of the food chains, which means that they sustain the entire food chain. 
When these organisms begin to die out, the higher levels of the food chain do not have sufficient food and the organisms at these levels begin to die out. Thus, the entire food chain is disrupted due water pollution.

The index of refraction of silicate flint glass for red light is 1.620 and for violet light is 1.660 . A beam of white light in
Sonja [21]

Answer:

10.16 degrees

Explanation:

Apply Snells Law for both wavelenghts

\(n_{1}sin\theta_{1} = n_{2}sin\theta_{2}\)

For red

(1.620)(sin 25.5) = (1)(sin r)

For red, the angle is 35.45degrees

For violet

(1.660)(sin 25.5) = (1)(sin v)

For violet, the angle is 45.6 degrees

The difference is 45.6- 35.45 = 10.16 degrees

Light travels at 3.0 × 108 m/s in a vacuum and slows to 2.0 × 108 m/s in glass. What is the index of refraction of glass?
Slav-nsk [51]
We are asked to solve for the index of refraction and the formula is n = c/v where "n" represents the index of refraction, "c" represents the speed of light in the vacuum while "v" represents the speed of another medium.
In the problem, we have the given values below:
c = 3 x 10^8 m/s
v = 2 x 10^8 m/s
n =?

Solving for n, we have the solution below:
n = 3x10^8 /  2x10^8
n = 1.5

The answer is 1.5 for the index of refraction.

An unstable particle at rest spontaneously breaks into two fragments of unequal mass. The mass of the first fragment is 3.00 10-
kirill [66]

Answer:0.478 c

Explanation:

Given

mass of lighter Particle(m_1)=3\times 10^{-28} kg

mass of heavier Particle(m_2)=1.51\times 10^{-27} kg

speed of lighter particle(v_1)=0.834 c

Let speed of heavier particle=v_2

and Momentum of the particle is given by

P=\frac{mv}{\sqrt{1-(\frac{v}{c})^2}}

P_1=\frac{m_1v_1}{\sqrt{1-(\frac{v_1}{c})^2}}

P_1=\frac{3\times 10^{-28}\times 0.834 c}{\sqrt{1-(\frac{0.834 c}{c})^2}}

P_1=8.219\times 10^{-28} kg c

P_2=\frac{m_2v_2}{\sqrt{1-(\frac{v_2}{c})^2}}

as momentum is conserved therefore P_1=P_2

8.219\times 10^{-28} kg c=\frac{1.51\times 10^{-27}\times v_2}{\sqrt{1-(\frac{v_2}{c})^2}}

v_2=0.478 c
