Two point charges (q1 = -4.1μc and q2 = 7.8 μc) are fixed along the x-axis, separated by a distance d = 9.5 cm. point p is located at (x, y) = (d, d). be sure to use a vector approach to answer these problems. it also limit the number of calculations since sometimes you can neglect one of the charge's effects due to its location relative to the point in question.

Find the dimensions and area of the largest rectangle that can be inscribed in the upper half of the ellipse. (give your answers in terms of a and b. enter the dimensions as a comma-separated list.)

Adiver named jacques observes a bubble of air rising from the bottom of a lake (where the absolute pressure is 3.50 atm) to the surface (where the pressure is 1.00 atm). the temperature at the bottom is 4.00 ∘c, and the temperature at the surface is 23.0 ∘c. what is the ratio of the volume of the bubble as it reaches the surface (vs) to its volume at the bottom (vb)? if jaques were to hold his breath the air in his lungs would be kept at a constant temperature. would it be safe for jacques to hold his breath while ascending from the bottom of the lake to the surface?
