The distance between two successive minima of a transverse wave is 3.10 m. five crests of the wave pass a given point along the direction of travel every 14.7 s. (a) find the frequency of the wave. hz (b) find the wave speed. m/s

The frequency is 0.34 Hz and the wave speed is 1.05 m/s.

Explanation:

Given that,

The distance between two successive minima of a transverse wave is wavelength.

Wavelength = 3.10 m

Time = 14.7 s

(I). We need to calculate the frequency

(II). We need to calculate the wave speed

Formula of wave speed

Where,

Put the value into the formula

Hence, The frequency is 0.34 Hz and the wave speed is 1.05 m/s.

probably not if net force is zero

the old price per ounce is c/4.

the new price per ounce is c/3.6.

the ratio of the old price to the new one is

(c/4)/(c/3.6) = (c/c)×(3.6/4) = 0.9 . . = 9/10 . . "nine tenths" in either form
