Based on the image below, what is the displacement of the sound wave for Sound A + B at 0.1025 seconds? A. -0.3316

B.0.3316

C.0.6255

D.1.6162

The displacement of the sound wave for Sound A + B at 0.1025 is;

D. 1.6162

Explanation:

The sum of the displacement of two sound waves is given by the principle of superposition as follows;

y(x, t) = ·sin(k·x - ω·t) + ·sin(k·x - ω·t + ∅)

Therefore, by the property of the superposition of waves, the amplitudes of linear waves are added linearly when they meet at the same point at a the same time

The given parameters for the wave are;

The time at which the value of the wave amplitude are given, t = 0.1025 seconds

The displacement of the sound wave A at the given time, "t" is A = 0.9739

The displacement of the sound wave B at the given time "t" is B = 0.6423  

Therefore, the displacement of the sound A + B = 0.9739 + 0.6423 = 1.6162

i'm not sure

explanation:

i'll try whatever you got

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.
