Two resistanceless rails rest 24 cm apart on a 4.0 ∘ ramp. They are joined at the bottom by a 0.70 Ω resistor. At the top a copper bar of mass 0.080 kg (ignore its resistance) is laid across the rails. The whole apparatus is immersed in a vertical 0.50 T field. Part A What is the terminal (steady) velocity of the bar as it slides frictionlessly down the rails

The electric field between square plates of a parallel-plate capacitor has magnitude e. the potential across the plates is maintained with constant voltage by a battery as they are pulled apart to twice their original separation, which is small compared to the dimensions of the plates. the magnitude of the electric field between the plates is now equal to a)e b)e/4 c)e/2 d)4e e)2e

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.
