Answer 1

Answer:

The answer is

$\frac{16}{9}$

Step-by-step explanation:

$\alpha + 2 \alpha = - 4 \\ 3 \alpha = - 4 \\ \alpha = \frac{ - 4}{3}$

(Sum of roots =-b/a)

$\alpha \times 2 \alpha = 2a \\ 2 { \alpha }^{2} = 2a \\ a = \frac{16}{9}$

(Product of roots =c/a)

Answer 2

Answer:

The voltage or electric potential difference across the terminals of a cell when no current is drawn from it. The electromotive force (emf) is the sum of the electric potential differences produced by a separation of charges (electrons or ions) that can occur at each phase boundary (or interface) in the cell
