The resulting positive amplitude of the two waves after the superimposition is 4.30 cm.
<h3>
Amplitude of the waves</h3>
The amplitude of the waves is the maximum displacement of the wave. This is the vertical position of the wave measured from the zero origin.
After the superimposition of the two similar waves, the resulting amplitude will be less than the initial amplitude of the wave with the highest vertical height since the superimposition creates destructive interference.
Resulting amplitude of the two waves is calculated as;
A = 5.4 cm - 1.10 cm
A = 4.30 cm
Thus, the resulting positive amplitude of the two waves after the superimposition is 4.30 cm.

Answer:
1.12×10⁻⁵ C and 2.24×10⁻⁵ C.
Explanation:
From coulomb's law,
F = kAB/r².............................. Equation 1
Where F = Force exerted by each charge, A = charge at point A, B = charge at point B, r = distance of separation between the points, k = constant of proportionality.
Given: F = 47 N, r = 22 cm = 0.22 m.
Constant: k = 9.0×10⁹ Nm²/C²
Let: B = q, the A = 2q.
Substituting these values into equation 1,
47 = 9.0×10⁹(q×2q)/0.22²
47 = 18×10⁹(q²)/0.0484
q² = (47×0.0484)/(18×10⁹)
q² = 0.126×10⁻⁹
q² = 1.26×10⁻¹⁰
q = √( 1.26×10⁻¹⁰)
q = 1.12×10⁻⁵ C
The charge at point A = 2q = 2× 1.12×10⁻⁵ = 2.24×10⁻⁵ C.
Hence the charges are 1.12×10⁻⁵ C and 2.24×10⁻⁵ C.
Answer:
Salts
Explanation:
When acids reacts with bases, salts and water are usually the product of such reactions. This reaction is called neutralization reaction.
A salt is an ionic compound which consists of positive and negative ions. Here, appropriate aqueous acid reacts with a water soluble base or water insoluble base. The product is usually salt and water.
