Answer:

The arrows always start at the magnet's north pole and point towards its south pole. When two like-poles point together, the arrows from the two magnets point in OPPOSITE directions and the field lines cannot join up. So the magnets will push apart (repel).

an oscilloscope has a time/div setting of 50ms and there are 10 divisions on the time scale. a sine wave on the oscilloscope dis
mamaluj [8]

Answer:

The frequency is f = 6Hz

Explanation:

Given

         The time division  setting is  d_t =50ms = 50*10^{-3}s

         The number of division is  n= 10

The total time for 10 division can be mathematically obtained as

         T_{total} = 10 *50*10^{-3}

                 =500 *10^{-3}s

From the question the time for 3 cycle is

        T_{total} = 500*10^{-3}s

Then the for one cycle which equivalent to the Period(T)  =  \frac{T_{total}}{3}

                                                               = \frac{500 *10^{-3}}{3}

The frequency is generally given as    f = \frac{1}{period} = \frac{1}{T}

    Now substituting values we have  

                              f = \frac{3}{500 *10^{-3}}

                                 = 6Hz
