Question

The difference between tidal energy and wave energy is that
a.Wave energy uses the gravitational pull of the Earth and moon to generate energy.
b.Tidal energy uses the kinetic force of waves to produce energy.
c.Tidal energy uses the gravitational pull of the Earth, moon and sun to generate energy.
d.None of these.

Answer 1

Hint: Tides and waves are two natural incidents that occur on the water. While they are identical in that they are associated with water, their ability to produce energy differs in a range of characteristics with regards to generation, energy and reliability.

Complete Step by Step Answer: Tides are defined as the surge and plunge of sea level induced by the gravitational pull of the moon and the sun on the Earth. These tides are influenced by a range of factors such as the sun and moons alignment, the pattern of the coastline and changes in the depth of water. Hence, tidal energy is renewable energy powered by nature.
-Its intensity is affected by the location and position of the Earth.
-It includes both kinetic and potential energy.
-It is an unsteady source of energy that is generated for about 6 – 12 hours at a time.
-The construction cost is higher than the maintenance cost.
Wave energy is defined as energy restrained from oceanic waves. Waves developed as an outcome of wind are usually referred to as wind waves and they occur effectively on water surfaces as there are no landmasses to withstand the power of the wind.
-Its intensity is influenced by wind strength.
-It includes only kinetic energy.
-A steady source of energy.
-Exceptionally high start-up costs are required to construct and formulate technology.

Hence, option 'c' is correct making all other options irrelevant.

Note: Tidal energy is used to provide electricity to homes and businesses and can be used in places instead of burning coal and oil that contribute to global warming.Wave energy is used for the transportation and capture of energy by ocean waves. The energy seized is then used for various kinds of work, comprising electricity generation, water desalination, and pumping of water.
