A squirrel is standing on an overhead telephone cable. At one end of the cable is a sensor that can record small vibrations. If the squirrel begins to run toward the sensor, such that either its front legs or hind legs land on the cable every 0.1 seconds, what frequency will be detected by the sensor? (A) exactly 0.1 Hz (B) between 0.1 Hz and 10Hz (C) exactly 10 Hz (D) slightly more than 10 Hz
Simple harmonic motion
Simple harmonic motion is a type of periodic motion in which an object undergoes oscillatory motion. The restoring force exerted by the object exhibiting SHM is proportional to the displacement from the equilibrium position. The force is directed towards the mean position. We see many examples of SHM around us, common ones are the motion of a pendulum, spring and vibration of strings in musical instruments, and so on.
Simple Pendulum
A simple pendulum comprises a heavy mass (called bob) attached to one end of the weightless and flexible string.
Oscillation
In Physics, oscillation means a repetitive motion that happens in a variation with respect to time. There is usually a central value, where the object would be at rest. Additionally, there are two or more positions between which the repetitive motion takes place. In mathematics, oscillations can also be described as vibrations. The most common examples of oscillation that is seen in daily lives include the alternating current (AC) or the motion of a moving pendulum.
