Two identical pendulums have the same period when measured in the factory. while one pendulum swings on earth, the other is taken on a spaceship traveling at 95% the speed of light. assume that both pendulums operate under the influence of the same net force and swing through the same angle. when observed from earth, how many oscillations does the pendulum on the spaceship undergo compared to the pendulum on earth in a given time interval? - more oscillations - fewer oscillations - the same number of oscillations

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.
