Sing the pre-lab questions as a guide, plan a way to determine the spring constant when the spring constant is set to Small. You may want to check with the TA on duty before proceeding What is your intended independent variable?

Scissors and a seesaw both cut things that’s the only comparison

  concave means having an outline or surface that curves inward like the interior of a circle or sphere. so the mirror curves inward.

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.

Answer it orbits high above earth to gain clearer images of light, it magnifies images relative to the human eye, it records most of the universe as it was in the past, not as it is now;
