You want to use the idea of electromagnetic induction to make the bulb in your small flashlight glow; it glows when the potential difference across it is 1.5 V. You have a small bar magnet and a coil with 100 turns, each with area 3.0×10⁻⁴ m². The magnitude of the 'B' field at the front of the bar magnet's north pole is 4.6×10⁻² T and reaches 0 T when it is about 4.0 cm away from the pole.
a) With what speed should you move the magnet to make the bulb light?
b) Can you make the bulb light? (yes/no/need more data)

True or false graphs must include scales that increase by the same amount

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.
