The gas then undergoes an isothermal 3 expansion to a volume of 200 cm . a. What is the final pressure of the gas

Iwould sure like to answer your question but i honestly just don’t know

The independent variable would be the fertilizer as it is what the dependent variable (the growth of grass) depends on.

The answer is as follows in the photo

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.
