Afireworks shell is accelerated from rest to a velocity of 50.0 m/s over a distance of 0.240 m. (a) how long (in s) did the acceleration last? s (b) calculate the acceleration in m/s^2). (enter the magnitude.) /s^2

True or false: the cycle of seasons on the earth is caused by the tilt of the earth on its axis toward and away from the sun.

How will the system respond to a temperature increase?

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.
