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.
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.Be careful when changing the 700nm into metres.mplitude is a measure of how big the wave is. 1  Imagine a wave in the ocean. 2  What you are actually seeing are waves with different amplitudes. 3  They might have the exact same frequency and wavelength, but the amplitudes of the waves can be very different.
