Answer:
The correct answer will be "". The further explanation is given below.
Explanation:
The potential energy will be,
⇒
The expression of force will be,
⇒
⇒
⇒
Force seems to be appealing because the expression has been negative. It therefore means that the force or substance is acting laterally in on itself.
Answer
given,
Length of the string, L = 2 m
speed of the wave , v = 50 m/s
string is stretched between two string
For the waves the nodes must be between the strings
the wavelength is given by
where n is the number of antinodes; n = 1,2,3,...
the frequency expression is given by
now, wavelength calculation
n = 1
λ₁ = 4 m
n = 2
λ₂ = 2 m
n =3
λ₃ = 1.333 m
now, frequency calculation
n = 1
f₁ = 12.5 Hz
n = 2
f₂= 25 Hz
n = 3
f₃ = 37.5 Hz
