Question

9. Which among the following is an adverse environmental impact of tidal power generation?
(a) Interference with spawning and migration of fish
(b) Wind mills
(c) Navigational hazard
(d) None of the above​

Answer 1

Answer:

Why is Indian coffee famous in the world? Where was it introduced in India initially? Name the places where it is cultivatedFactors of 200 are the numbers that multiplying two natural numbers give the result 200. There are a total 12 factors of 200 which can be negative as well as positive. Did you know that in 200BC the building of The Great Wall of China was begun? In this lesson, we will calculate the factors of 200, its prime factors, and its factors in pairs along with solved examples for a better understanding.

Factors of 200: 1, 2, 4, 5, 8, 10, 20, 25, 40, 50, 100, and 200.

Factors of -200: -1,- 2, -4, -5, -8, -10, - 20, -25, -40, -50, -100, and -200.

Prime Factorization of 200: 200 = 23 × 52

What are Factors of 200?

One of the easiest ways to find out all the factors is to list all the possible pairs of numbers which can give you the product as 200. Here are all the possible pairs of numbers:

(1,200), (2,100), (4,50), (5,40), (8,25), (10,20)

Therefore, the factors of 200 are 1, 2, 4, 5, 8, 10, 20, 25, 40, 50, 100, and 200. Which means the number 200 is an evenan account of a person's life written by that person.

Answer 2

Answer:

Among the given option the adverse environmental impact of tidal power generation is -

(d) None of the above​

Explanation:

Following are the adverse environmental impact of tidal power generation

1. Site Availability Constraints - Site availability constraints remain a major constraint in the development of tidal power projects. The developments should also lead to a reduction in  the  economic and ecological costs of the projects and thus increase their availability.
2. Locations close to shore - Tidal power plants have to be built close to shore because high tidal currents are required to generate electricity. Large fluctuations in tides and tidal speeds can significantly increase a site's potential  for tidal power generation. Although places where the tides fluctuate offer greater potential for tidal projects, scientists are trying to develop technologies that can generate enough electricity even when the tide is low.
3. Environmental Impacts - The environmental impacts of tidal power projects have not yet been precisely determined.Tidal energy can harm marine life, as tidal turbines can kill marine life with their spinning blades. Noise from rotating turbines can also affect fish housing at tidal power sites. Tidal energy can also affect water quality  and sedimentation processes.
4. Tidal Embankment - The installation of a tidal embankment can alter the shoreline within a bay and damage an ecosystem that depends on tidal flats.Manhole flushing can also be affected by preventing water flow  in and out of the manhole. As a result, there may be a reduction in salt water, affecting marine life.
