For some resistor applications, it is important to maintain a fixed value of resistance over a range of operating temperatures. explain briefly how you could minimize variations (resulting from changes in temperature) in the resistivity of si at temperatures near 300k. assume that you are free to choose the value of resistivity.

Ihope you get it right bro

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

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.
