What iron gives in its abundance, it takes away in it's inability to really conduct heat and electricity well. There is enough copper around, if we are careful in its use, to make copper bottomed pots and pans. Of the three best conductors in the world (silver, gold and copper) only copper has enough around and can be inexpensively mined that we make use of it.
If you google dr. copper, you will find he is an economist as well. Copper measures the wealth of an economy by how much is used. So iron might be cheaper and more abundant, but copper will save you much more in trying to do something with it.
Answer:
2m/s²
Explanation:
When an object starts or at its state of rest it has an Initial speed U = 0
Final speed = 6m/s
total time taken for the acceleration = 3s
Acceleration =?
Acceleration is the change in velocity (speed) with time
OR
Time rate of change of velocity
Acceleration = <u>Change in Speed(velocity)</u>
Time taken
Hence,
Acceleration = <u> </u><u> </u><u>V - </u><u>U</u><u> </u><u> </u>
t
a = <u>6</u><u> </u><u>-</u><u> </u><u>0</u>
3
a = <u>6</u><u> </u><u> </u>
3
a = 2m/s²
