There is no chart provided in this statement. However, the current that flows within an electrically charged item is dependent on how it is arranged. There are two kinds of current and these are, parallel and circuit currents. Current that flows in parallel current is less than when it is farther away from the electric source; current that flows in a series current flows at a constant rate regardless of how far it is from the electrical source.
<u>Answer:</u> The ball is travelling with a speed of 5.5 m/s after hitting the <u>bottle.</u>
<u>Explanation:</u>
To calculate the speed of ball after the collision, we use the equation of law of conservation of momentum, which is given by:
where,
are the mass, initial velocity and final velocity of ball.
are the mass, initial velocity and final velocity of bottle.
We are given:
Putting values in above equation, we get:
Hence, the ball is travelling with a speed of 5.5 m/s after hitting the bottle.
The wavelength of the interfering waves is 3.14 m.
<h3>Calculation:</h3>
The general equation of a standing wave is given by:
y = 2A sin (kx) cos (ωt) ......(1)
The given equation represents the standing wave produced by the interference of two harmonic waves:
y = 3 sin (2x) cos 5t .......(2)
Comparing equations (1) and (2):
k = 2
We know that,
k = 2π/λ
λ = 2π/k
λ = 2 (3.14)/ 2
λ = 3.14 m
Therefore, the wavelength of the interfering waves is 3.14 m.
I understand the question you are looking for is this:
Two harmonic waves traveling in opposite directions interfere to produce a standing wave described by y = 3 sin (2x) cos 5t where x is in m and t is in s. What is the wavelength of the interfering waves?

Hi, what is it you need help with?
Answer:
60 m/s (in the opposite direction)
Explanation:
By conservation of momentum,
Initial momentum of board + Initial momentum of man = Final momentum of board + Final momentum of man
=> 0 + 40*12 = 8*(-v) + 0
=> v = -60 [ Negative indicates opposite direction ]
