Aloop of current-carrying wire has a magnetic dipole moment of 5.0 x 10–4 a·m2. the moment initially is aligned with a 0.50-t magnetic field. to rotate the loop so its dipole moment is perpendicular to the field and hold it in that orientation, you must do work of

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.)

In positive numbers less than 1, the zeros between the decimal point and a non-zero number are blank significant
