Find the terminal speeds in air of
(a) a steel ball bearing of diameter 3 mm,
(b) a 16-pound steel shot, and
(c) a 200-pound parachutist in free fall in the fetal position. in all three cases, you can safely assume the drag force is purely quadratic. the density of steel is about 8 g/cm 3and you can treat the parachutist as a sphere of density 1 g/cm 3 .

What term do psychologists use to designate our personal awareness of feelings, sensations, and thoughts?

An air-filled capacitor is formed from two long conducting cylindrical shells that are coaxial and have radii of 26 mm and 103 mm. the electric potential of the inner conductor with respect to the outer conductor is - 700 v (k = 1/4πε 0 = 8.99 × 109 n · m2/c2) the energy stored in a 1.0-m length of this capacitor is closest to

Aflask with vinegar in it has a mass of 160 grams. a balloon with baking soda in it has a mass of 40 grams. the balloon is attached to the flask to seal the opening and the vinegar and baking soda mixes. the balloon inflates to a large volume. what will the total mass of the balloon and flask be after the balloon inflates? explain. a) less than 200 grams because the solid baking soda disappears. b) 200 grams, because all the atoms remain in the balloon or flask. c) more than 200 grams because the size of the balloon is so much larger. d) less than 200 grams because gases such as the one in the balloon are lighter than solids and liquids.
