(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;

v = \sqrt{\frac{T}{\mu} }

where;

  • μ is mass per unit length = (0.26 kg)/(2 m) = 0.13 kg/m
  • T is tension

v = \sqrt{\frac{50}{0.13} } \\\\v = 19.6 \ m/s

<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>

T = \frac{2\pi }{\omega } \\\\T = \frac{2\pi }{653.72} \\\\T = 0.0096 \ s

<h3>Wavelength</h3>

v = fλ

λ = v/f

λ = 19.6/50

λ = 0.392 m

Hey there, Your answer wold be 1.36 newtons rounded to 1.4 newton. This is how!

force = k (q1 * q2) / r^2 

<span>= (9.0 × 10^9 Nm^2/C^2) [(7.1 × 10^-6 C) (6.9 × 10^-6 C)] / (5.7 × 10^-1 m)^2 
</span>
<span>= [ 9.0 × 7.1 × 6.9 / (5.7)^2 ] × 10^-1 N 
</span>
