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:
The most accurate and precise method to measure the thickness of a coin would be by a micrometer screw guage.
Answer:
0.033 m/s²
Explanation:
Given:
Δx = 2500 m
v₀ = 1.4 m/s
v = 13 m/s
Find: a
v² = v₀² + 2aΔx
(13 m/s)² = (1.4 m/s)² + 2a (2500 m)
a = 0.033 m/s²
Because your arteries are directly connected to your heart meaning there is more blood flow
Astronomers suspected an eighth planet beyond Uranus because of the irregularities in the motion of Uranus suggested that gravity from another planet was affecting it.
<h3>Who is an astronaut?</h3>
It should be noted that an astronaut simply means an individual who is trained to travel in spacecrafts.
In this case, astronomers suspected an eighth planet beyond Uranus because of the irregularities in the motion of Uranus suggested that gravity from another planet was affecting it.
In mid-1800s, astronomers used the orbits of most asteroids to predict where a planet would have to be.
