Will the velocity of the book change as it moves across the surface WITH friction? Explain your answer.

Why there is no inductive reactance in dc circuits

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.)

Distinguish between a transverse wave and a longitudinal wave.
