Natural frequencies are different fromforced frequencies, which occur by applying force to an object at a specific rate. The forced frequency can occur at a frequency that is the same as or different from the natural frequency. When the forced frequency is not equal to the natural frequency, t...

Private speaking, in a few words, can be defined asclose or confidential conversationwith others, and also as conversation that frequently seeks to uncover, disclose, elicit, or enable insight or learning. Private speaking is the intimate natural communication of counselors and confidants, whether th...
Find the frequency of the vibration.Two different simple harmonic oscillators have the same natural frequency (f=5.60 Hz) when they are on the surface of the Earth. The first oscillator is a pendulum, the second is a vertical spring and...
