1) Tides are the result of the gravitational attraction of moon and sun acting upon the rotating earth.
2) The highest level of water is known as Ebb.
3) Tidal energy has low energy density.
Which of the following statements is/are Not correct _________?
Question 2
Statement-I: When Sun, moon and Earth are in conjunction, they result in tides of maximum range.
Statement-II:Spring tides occur twice per lunar month at times of both full and new moon.
Question 3
The energy flux in ocean water waves is _________.
Question 4
Astronomers found a new Earth like planet with 58% of its area is filled with a liquid of specific gravity 0.9 and gravitational force is 75% of Earth’s gravitation. For this Planet, Moon revolves around it’s with lunar cycle of 20 hours. If periodic rise/fall of liquid on that planet is similar to Earth’s Ocean/See then what would be average tidal power that could be generated. If single action tidal power plant set up there with area of basin of 50 km2 and range of 10 m. [Assume g = 9.8 m/s2]
Question 5
Consider the following statements:
1) Neap tides forms when sun-earth and moon earth directions are perpendicular to each other.
2) Neap tides occur only once in a month at times of half moon.
3) One of the main advantages of tidal energy is that it requires very low capital cost at most potential installations.
Which of the following statements is/are correct ________?
