As an electron moves through a region of space, its speed decreases from 6.03 × 106 m/s to 2.45 × 106 m/s. the electric force is the only force acting on the electron. (a) did the electron move to a higher potential or a lower potential? (b) across what potential difference did the electron travel?

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.
