What is the resistance of a 1.3 m copper wire ( = 1.7 10-8 m) that has a cross-sectional area of 8.36 10-6 m2?

another example of kinetic energy would be,

kinetic energy   >     moving energy

answer   >   letter choice (c),   a hammer falling off a table.

hope that !                                         : )

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
