The frequency of a wave is just the reciprocal of the period.
For this one . . .

Frequency = 1/(period) = 1/(5 sec) = 0.2 per sec (0.2 Hz) .

Answer:

Frequency of the wave is 0.2 Hz.

Explanation:

It is given that, the period of a mechanical wave is 5 seconds. We have to find the frequency of the wave. Time period of a wave is defined as the time taken by the wave to complete one cycle and the number of oscillations or vibrations in a medium is called the frequency of the wave.

The relationship between the time period and the frequency of the wave is given by :

$f=\dfrac{1}{T}$ T = time period

$f=\dfrac{1}{5\ s}$

f = 0.2 Hertz

Hence, the correct option is (c) " 0.2 Hz ".

Andrews [41]

Answer:

The length of the resultant vector is 50 inches

Explanation:

Use the Pythagorean theorem to find the answer, since the addition of these two perpendicular vectors will have a magnitude (length) equal to the hypotenuse of the right angle triangle formed by the two:

$|Resultant|\,=\,\sqrt{x^2+y^2} \\|Resultant|\,=\,\sqrt{48^2+14^2}\\|Resultant|\,=\,\sqrt{2304+196}\\|Resultant|\,=\,\sqrt{2500}\\|Resultant|\,=\,50\,in$
