Describe the motion of a swing that requires 6 seconds to complete one cycle. What is its period and the frequency? Round to the nearest hundredth.

Period = 6 seconds and .

Explanation:

We have , the motion of a swing that requires 6 seconds to complete one cycle. Period is the amount of time needed to complete one oscillation . And in question it's given that 6 seconds is needed to complete one cycle. Hence ,Period of the motion of a swing is 6 seconds . Frequency is the number of vibrations produced per second and is calculated with the formula of   . SI unit of frequency is Hertz or Hz. We know that time period is 6 seconds so frequency =  

⇒

⇒

⇒

Therefore , Period = 6 seconds and .

i think it because equal matrices have equal dimensions, only square matrices can be symmetric. for all indices and . every square diagonal matrix is symmetric, since all off-diagonal elements are zero. in linear algebra, a real symmetric matrix represents a self-adjoint operator over a real inner product space.

probably not if net force is zero
