Aball thrown in to the air starts out with an initial upward velocity but eventually slows and stops before falling back to the ground. which of the following contributes the most to the change in the motion of the ball? question 2 options: a) the initial force with which the ball was thrown b) the downward force of gravity c) the resistance against the atmosphere d) the increase of inertia.

Beryl states that insulation with the smallest possible thermal conductivity is best to keep a house warm in winter, but worst for keeping a house cool in summer. sapphire insists the reverse is true: low thermal conductivity is good in the summer, but bad in the winter. which one, if either is correct? a. beryl, because low thermal conductivity results in low heat transfer. b. beryl, because low thermal conductivity results in high heat transfer. d. sapphire, because low thermal conductivity results in high heat transfer. e. neither, because low heat transfer is desirable both in summer and in winter.
