If the wavelength of one wave is 0.25 meters, how many waves will be formed on a rope that is one meter long?

4 waves

Wavelength of one wave = 0.25 meters

Length of the rope = 1 meter

Therefore;

Number of waves = Length of the rope/wavelength of one wave

                              = 1/0.25

                              = 4 waves

what was the answer?

energy stored in the capacitor= 9.72 x 10⁻⁴ j

explanation:

the energy stored in the capacitor is given by

e= 1/2 c v²

e= energy stored

c= capacitance= 1.5 µc= 1.5 x 10⁻⁶f

v= potential difference=36 v

so energy stored= e= 1/2 (1.5 x 10⁻⁶) (36)²

energy stored= 9.72 x 10⁻⁴j
