Refraction occurs when a wave enters a new medium and changes its speed.
i hope this helps
Where are the following awnsers?
Answer:
Displacement is 50 m
Explanation:
Distance is simply the measurement of the sum of all paths travelled.
Thus, since he swims the 50m length pool 3 times, then the total distance = 50 × 3 = 150 m
Whereas, displacement is the measurement of length of the shortest path from initial point to final point.
In this case initial point to final point is 50m. Thus, the displacement is 50 m
Answer:
Explanation:
1) Hypermetropia (better known as Farsighted- this is why nearby objects seem blurry for him)
2) In such instances, image are typically formed farther from the near point
3) Such defects are quite common so there are common procedures such as using convex lens which can restore the sight to normal.
Answer:
C. Each capacitor carries the same amount of charge.
Explanation:
When two or more different capacitors are connected in series across a potential source, each capacitor carries the same amount of charge.
In a series connected capacitor, sane amount of charge flows through the capacitors while different potential difference is passed across them.
The capacitors have the same charge as the charge flowing out directly from the potential source called emf since the emf is the driving force of charge in a circuit.
