Select the correct answer. The formula for calculating power is work divided by time (power = work ÷ time). What are two ways of stating the same relationship? work = power ÷ time work = power × time time = work ÷ power time = work × power power = work × time

work = power × time

time = work ÷ power

Explanation:

Power is defined as the rate at which work is done.

 It is mathematically expressed as;

     Power  =  

 From this expression, if we cross multiply, we get;

        work  = power x time

Also,   if we divide both sides by power, we get;

      time  = work ÷ power

f=ma newton

f=100x2.5=250n

the minimum amperage that the current in this wire would have to have so that its weight is completely supported by the magnetic force due to earth's field, assuming that no other forces except gravity act on it
