no, it not useless. we still learn Bohr's model in HS n dats almost 200 yr old! while there may be new models, previous one is good for explaining the basics. it is also useful to learn previous model n see how our understanding improves over time.
For electrical devices . . .
Power dissipated = (voltage) x (current) =
(12 V) x (3.0 A) = 36 watts .
1 watt means 1 joule per second
(36 joule/sec) x (60 sec/min) x (10 min) = 21,600 joules
B I believe is the answer!
Hope this helps and have a great day!!!
The cause would be how the idea started or developed and the effect would be how they both effected you together
no it can't do this why because I think that it is water and it can not go any where.
