(a) The amplitude of the wave is 3 cm.
(b) The speed of the wave is 19.6 m/s
(c) The angular frequency is 653.72 rad/s.
(d) The period of the wave is 0.0096 s.
(e) The wavelength of the wave is 0.392 m.
<h3>
Speed of the wave</h3>
The speed of the wave is calculated as follows;
where;
- μ is mass per unit length = (0.26 kg)/(2 m) = 0.13 kg/m
- T is tension
<h3>Angular frequency</h3>
ω = v/r
ω = v/A
ω = 19.6/0.03
ω = 653.72 rad/s
<h3>Period of the wave</h3>
<h3>Wavelength</h3>
v = fλ
λ = v/f
λ = 19.6/50
λ = 0.392 m

Answer:
if one wave has a negative displacement, the displacements would be opposite each other, so the displacement where the waves overlap is less than it would be due to either of the waves separately.
-causes a moment where the net displacement of the medium is zero. energy of waves hasn't vanished, but it is in the form of the kinetic energy of the medium
-then both emerge unchanged
Explanation:
Answer:
the statement is true
Explanation:
The bonds in the molecules give rise to irrational energy levels, are quantized, that is, they are discrete
In order for a photon to create a transition between the given levels it has to have the same energy as these two levels, it is in this case if the photon has the energy of the bond can be promised to the electron and be absorbed.
In summary the statement is true
Answer:
The meaurement of the amount of friction a surface will generate is called the coefficient of friction.
