Both rolling resistance and drag increase with increasing speed as the square of the speed

What will be an ideal response?


Not so: rolling resistance is relatively constant, but drag does increase with speed
(for great enough speed) as the square of the speed.

Why isn't there a planet where the asteroid belt is located?

A) There was not enough material in this part of the solar nebula to form a planet. B) A planet once formed here, but it was broken apart by a catastrophic collision. C) Gravitational tugs from Jupiter prevented material from collecting together to form a planet.
