Explanation:
It's the definition of "Cognitive Dissonance".
Answer: (1) The correct answer is A.
(2) The correct answer is D.
Explanation:
(1)
Reflection is the sending back of light from the surface without absorbing it. In the reflection phenomenon, the wave does not continue moving forward.
Diffraction is the bending of the light around the obstacle. In the diffraction phenomenon, the wave travels forward after striking around the obstacle.
Therefore, the correct answer is A.
(2)
Amplitude is the maximum displacement in the medium from the rest position.
The amount of energy is related to the amplitude. Amplitude is related to the amount of energy carried by the wave. Low energy wave is characterized by a low amplitude. High energy wave is characterized by a high amplitude.
Therefore, the correct option is D.
Answer:
delay or stifle the emergence of the perspective
Fluid mechanics deals with pressure and internal forces in the fluid. So the correct answer should be a) how fluids do work.
If you put two solids in contact, there will be a contact force created between them. Since Pressure = Force / Area, the correct answer should be b) exert pressure on each other.
