If a runner's power is 400 W as she runs, how much chemical energy does she convert into other forms in 10.0 minutes?

Explanation:

A Watt is defined as a Joule per second. 10.0 minutes, converted in seconds, are . At this point, we just multiply the two numbers:

explanation: magnetic pole, region at each end of a magnet where the external magnetic field is strongest. the south-seeking pole, or any pole similar to it, is called a south magnetic pole. unlike poles of different magnets attract each other; like poles repel each other.

force required to detach it is given by

charges are taken to be fundamental charge

now we have

so above is the minimum distance at which it will detach
