A single axle trailer has a sole set of wheels; a tandem axle has two sets of wheels. Simple counting can tell you which type of trailer youâre looking at, making it easy to compare trailers and determine which one suits your needs best.
A pendulum makes 36 vibrations in exactly 60 s. What is its (a) period, and (b) frequency? 7. How long must a simple pendulum be if it is to make exactly one swing per second? (That is, one complete vibration takes exactly 2.0 s.) 8.. If a simple pendulum whose length is 1.50 m makes 72 oscillations in 3.00 min, what is the acceleration of gravity at its location? 5. A 2500 kg demolition ball swings on a cable 17.0 m long.
Since frequency and period are exact inverses of each other, there is a very basic pair of formulas you can use to calculate one if you know the otherâ¦. It is very easy to do these calculations on calculators using the x-1 button. Example 1: The period of a pendulum is 4.5s. Determine the frequency of this pendulum. The period means that it will take 4.5 seconds for the pendulum to swing back and forth once. So, I expect that my frequency will be a decimal, since it will complete a fraction of a swing per second.
