Release the car and record there time from the photogate at the bottom of the hill. what is the potential energy at the end of the loop? what is the kinetic energy at the end of the loop (based upon the photogate time)? oh also can you help me find the speed of the car at the bottom of the hill like i know speed is distance multiples by time but i don’t know what number to use for distance

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.
