The electromotive force (∈) = 2 V
<h3>Further explanation</h3>
Given
I=2 A
t = 30 s
E = 120 J
Required
The electromotive force (∈)
Solution
The electromotive force : the potential difference between two electrodes in galvanic cell
Can be formulated :

E = energy, J
Q = charge , Coulomb = i.t

<span>Debido a que la fuerza es constante, a medida que la masa aumenta, la aceleración disminuye. Por lo tanto, la mayor aceleración sería a1.</span><span>Utilicé Google traductor, lol. Sin embargo, espero que esto ayude.</span>

Answer:
So increasing the voltage increases the charge in direct proportion to the voltage. If the voltage exceeds the capacitors rated voltage, the capacitor may fail due to breakdown of the dielectric between the two plates that make up the capacitor.
Explanation:
A option.
I believe your mass on the moon would be lighter than on earth because there is no gravity on the moon
