<span>A) The force multiplied by the time the objects are in contact.
Hope this helps!</span>
Answer:
The electromotive force is the voltage measured across the cell terminals when "NO" current is being drawn. That is why electromotive forces are used in Wheatstone Bridges which measure the resistance of an external object.
Just measuring the voltage across a cell does not give one the true EMF because current drawn from the cell will cause a reduction of voltage of I * R where R is the internal resistance of the cell.
The answer would be 27,000 Joules because (1/2) m v^2 =30*900 which equals 27,000 J
Answer:
increase in the resistance profit accompanying an increase in temperature.
Explanation:
The fighting of the leader is equivalent to the hotness. The increase in hotness of the leader increases allure opposition.
