Probably the deadliest aspect of a thunderstorm is lightning .
They will interfere to create a crest with an amplitude of 2.
They will interfere to create a crest with an amplitude of 0.
They will bounce off each another.
Answer:
They will interfere to create a crest with an amplitude of 2.
Explanation:
The two waves will interfere and the resultant amplitude will be given by the principle of superposition, which states that the resultant amplitude is given by the sum (or the difference, if they meet in opposite phase) of the amplitudes of the two waves. In this case, the crest of wave C meets the through of wave D, so they are in opposite phase, therefore the resultant amplitude will be
A = A(C) - A(D) = 3 - 1 = 2
Answer:
benefit from primacy
Explanation:
WOlf93 I 100% agree with you... dont look like a hobo ppl lol
Reactivate
B) a glow stick
C) photosynthesis
D) a hydroelectric dam
The question involves the concepts of chemical energy, light energy and energy conversion.
The example which involves the transformation of chemical energy directly into light energy is "B) a glow stick".
A)
In a windmill, the input energy is the wind energy, and that wind energy is then converted to mechanical energy when the rotor blades rotatae. That mechanical energy is then converted to electrical energy. This electrical energy is then used in lamps to get light energy. Hence, the chemcial energy is not directly transformed into light energy in the windmill.
B)
A glow stick uses the chemical energy from the chemicals inside it to produce luminance in the form of light energy. When the stick is bent or broken, it releases the chemicals inside it which undergo a chemical reaction that leads to the conversion of chemical energy into light energy.
C)
During photosynthesis, light energy is used by plants to produce oxygen and energy in the form of sugar (glucose).
D)
A hydroelectric dam receives mechanical energy from water. The gravitational potential energy of water due to its height is converted into kinetic energy when it reaches the turbine. This kinetic energy is then converted to electrical energy.
Hence, the only example where chemical energy is directly converted to light energy is Glow Stick.
