A glass window of width W 1 m and height H 2 m is 5 mm thick and has a thermal conductivity of kg 1.4 W/mK. If the inner and outer surface temperatures of the glass are 15 C and 20 C, respectively, on a cold winter day, what is the rate of heat loss through the glass

When many atoms are split in a chain reaction, a large explosion occurs. this is an example of what type of energy conservation

Part 1: a magnetic levitation or maglev train rides rails without touching them. explain how this works using your data. include the appropriate magnet drawing in your answer. part 2: two objects are near a bar magnet. one is about 1 cm away, while the other is 6 cm away. compare and contrast the magnetic force that affects each object. use your data to answer the question

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.
