During the pyramid-building era the ancient Egyptians used two units of length, the palm and the ell. An ell was 7 palms and a palm was about 3 inches. If a hawk is tracked at a diving speed of 3 ells per second, what is its speed in inches per second? 1. 42 in/s 2. 5.25 in/s 3. 0.7 in/s 4. 126 in/s

"induction" is the process of charging an object without touching it.hope my answer has you : )

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.
