Question

A small marble attached to a massless thread is hung from a horizontal support. When the marble is pulled back a small distance from equilibrium and released, it swings in simple harmonic motion with a frequency ????f.

What is the frequency of the pendulum if the length of the thread is increased by a factor of 4,4, but the marble is still released in the same way?
a,4????4f
b.2????2f
c.????f
d.????2f2
e.????4

Answer 1

The frequency of the pendulum remains the same when the length of the thread is increased by a factor of 4.4.

Step-by-step explanation:

The frequency of a pendulum is determined by the length of the pendulum and the acceleration due to gravity. When the length of the thread is increased by a factor of 4.4 while the marble is still released in the same way, the frequency of the pendulum does not change.

Therefore, the frequency of the pendulum is the same, which is represented by the symbol ????f. The correct answer is c. ????f.
