Water exits a garden hose at a speed of 1.2 m/s. if the end of the garden hose is 1.5 cm in diameter and you want to make the water go 15 m high, what fraction of the area of the hole do you have to block off with your thumb? a : 93%b : 14%c : 7.0%d : 73%e : 27%

Good moring let me you on this question the answer the electric force  have a good day ; )

Answerthe energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.explanationwe define electric potential as the ratio electric potential energy to the charge,    then the following gives us the potential difference,      the formula  may be on your formula sheet.the change in electric potential energy would be the energy that would needed to move it from point a to point b. solving for that, we get    using q = 8.00  × 10⁻¹⁹ c and  δv = 2.00 v, we get    the energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.
