This set of Applied Chemistry Multiple Choice Questions & Answers (MCQs) focuses on “Tidal and Wave Power – 1”.
1. Tidal energy is a form of ________
a) Wind power
b) Solar power
c) Heat energy
d) Hydro power
View Answer
Explanation: Tidal power is also called as tidal energy. It is a form of hydro power. It converts the energy obtained from tides into useful forms of power mainly into electricity.
2. Tidal energy has ________ for future electricity generation.
a) Kinetic energy
b) Potential
c) Wind power
d) Solar power
View Answer
Explanation: Tidal energy has the potential for future electricity generation. Tidal are more predictable than wind energy and solar power.
3. Which of the following is the best form of energy that can be used at any time?
a) Wind energy
b) Solar energy
c) Tidal energy
d) Heat energy
View Answer
Explanation: The wind energy and solar energy are the most uncertain sources. The solar energy can not be taken when it is cloudy and the wind cannot be blown all the time. So, the tidal energy can be drawn any time.
4. The worlds large scale tidal power plant is __________
a) Rance tidal power plant
b) Uldolmok tidal power plant
c) Kislaya guba tidal power plant
d) Jiangxia tidal power plant
View Answer
Explanation: The worlds largest tidal power plant is Rance tidal power plant. It is located at France. The Uldolmok tidal power plant is located at south Korea.
5. The oceanic tides are due to __________
a) Heavy Winds
b) Slight earth quakes
c) Water force
d) Gravitational interaction
View Answer
Explanation: The oceanic tides are due to the gravitational interaction. The gravitational interaction is with the sun and moon and also due to earth’s rotation.
6. Tidal power is practically _________
a) Exhaustible
b) Inexhaustible
c) Not possible
d) Complicated
View Answer
Explanation: The tidal power is practically inexhaustible. The oceanic tides exist at any time and their occurance is certain and most predictable.
7. Movement of tides causes the loss of _________ in earth moon system.
a) Static energy
b) Frictional energy
c) Mechanical energy
d) Kinetic energy
View Answer
Explanation: Movement of tides causes the loss of the mechanical friction in earth moon system. It is due to the pumping of water through natural restrictions around the coastal line and consequent viscous dissipation at the sea bed.
8. The loss of mechanical energy due to movement of tides in earth moon system causes the rotation of earth _______
a) Slow
b) Fast
c) Very fast
d) Remains same
View Answer
Explanation: The loss of mechanical energy due to the movement of tides in earth moon system causes the rotation of earth slow in a couple of years after its formation.
9. The slow down of earth’s rotation due to the loss of mechanical energy of earth moon system is since _______ years from earth’s formation.
a) 1 billion
b) 2.5 billion
c) 3.5 billion
d) 4.5 billion
View Answer
Explanation: The earth’s rotation is slow down due to the loss of mechanical energy of earth moon system. It is slowed down after 4.5 billion years after its formation.
10. During the last 620 billion years, the earth’s period of rotation is ________ than that of the rotation of earth since its formation.
a) Faster
b) Slower
c) Very faster
d) No change
View Answer
Explanation: As we already came to know that the earth’s rotation was slowed down after 4.5 billion years from its formation. So, for every 4.5 billion years the earth’s rotation slows down more.
