Correct Answer: normal faults
Explanation:
Tensional forces normally cause normal faults.
Correct Answer: point at which a person notices something and becomes annoyed
Correct Answer: magma
Explanation:
Magma is molten rocks beneath the earth's crust. Hot springs are heated geothermally by underlying magma.
Correct Answer: Turbines
Explanation:
Turbines are machines powered by rotating blades.
Correct Answer: electron
Correct Answer: it contains the maximum content of water vapour
Explanation:
Air is said to be saturated when it contains the maximum content of water vapour.
Correct Answer: when the objects meet
Explanation:
Force of impact is the force when the objects meet. The speed of the object plays an important role in the generation of force of impact. The laws of physics determine that the force of impact increases with the square of the increase in speed.
Correct Answer: All of the above
Explanation:
Unbalanced forces are the forces which causes change in motion of the object. It sets the object in motion and may cause the object to move. If the object is already in motion, it changes the speed and direction of the object.
Correct Answer: Electrical energy
Correct Answer: 450 mm Hg
Explanation:
450 mm Hg denotes the air pressure.
