Energy required = mass x specific heat x temperature difference
= 0.5 x 4.19x10^3 x 2
= 4190J
Answer:
I = 1.944 A
Explanation:
<u>Given the following data;</u>
Charge, Q = 3.5C
Time, t = 1.8 secs
Charge of a substance is given by the formula;
Where;
Q is the amount of charge measured in Colombs.
I is the current measured in Amperes.
t is the time measured in seconds.
Making I the subject of formula, we have
I = 1.944 A
Therefore, the current in the circuit is 1.944 Amperes.
Because in the outcome your making a profit because the transportation would be cheaper for your company
