Answer:
The tension in the string when the speed increased is 134.53 N
Explanation:
Given;
Tension in the string, T = 120 N
initial speed of the transverse wave, v₁ = 170 m/s
final speed of the transverse wave, v₂ = 180 m/s
The wave speed is expressed as;
where;
μ represents mass per unit length
The new tension T₂ will be computed as;
Consequently, the tension in the string when the speed was increased is 134.53 N
When an electric dipole is subjected to an electric field, it experiences a torque given by the equation torque = p x E = p E sinθ, where θ represents the angle between p and E. The torque will be zero when θ equals 0, aligning both p and E, which is a stable orientation. If θ is 180°, the torque also equals zero since p and E point in opposite directions, representing an unstable orientation because even a slight deflection will revert to the stable position due to torque from the electric field.
