A meteor falls from the sky to the earth. The meteor already had an initial velocity downward shen it was spotted. If it high earth at 335 m/s after being seen for 30 seconds, then what is the initial velocity of the meteor? The meteor accelerates at 10 m/s squared.

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.
