Which statement is true? inner and outer planet composition supports the nebular theory because heavier elements condense close to the sun, and lighter elements condense at cooler temperatures. the big bang is a theory about the origin of the solar system. nuclear fusion occurs at cooler temperatures, away from the sun. the inner planets are gas giants, and the outer planets are rocky.

Asmall metal bar, whose initial temperature was 10° c, is dropped into a large container of boiling water. how long will it take the bar to reach 70° c if it is known that its temperature increases 2° during the first second? (the boiling temperature for water is 100° c. round your answer to one decimal place.) sec how long will it take the bar to reach 98° c? (round your answer to one decimal place.)

Two resistors r1 and r2 may be connected either in series or parallel across an ideal battery with emf ε. we desire the rate of energy dissipation of the parallel combination to be 8.75 times that of the series combination. if r1 = 105 ω, what are the (a) smaller and (b) larger of the two values of r2 that result in that dissipation rate?
