Answer:
Current that reverses direction in the regular pattern is called an alternating current, abbreviated as 'AC'.
Explanation:
hope this helps!
The atoms vibrate faster and the space between atoms spread
<span>A mechanical wave is created when a source of energy causes a vibration to travel through a medium
And yeah lol
A mechanical wave is a disturbance in matter that carries energy from one place to another :)
This what you needed? </span>
Answer:
Interference
Explanation:
Interference is a phenomenon that occurs when two waves meet while traveling along the same medium.
Answer:
The time taken for the sound wave to make the round trip is 0.16 s.
Explanation:
Given;
distance traveled by the sound wave, d = 120 m
bulk modulus of sea water, B = 2.3 x 10⁹ N/m²
density of sea water, ρ = 1022 kg
The speed of the wave is given by;
Speed is given by;
total distance of the round trip = 2 x 120m = 240 m
Time taken for the sound wave to make the round trip is given by;
Therefore, the time taken for the sound wave to make the round trip is 0.16 s.
