Answer:
B.) The energy a spring has by being compressed
Explanation:
yessir
Answer:
8.18 × 10 ⁻²¹.
Explanation:
The potential energy may be defined as the energy stored in the rest objects. This energy is important for the maintenance of the concentration gradient in the cell.
The change in the potential energy can be calculated as follows:
W = v2-v1 × q.
Here, the charge of the proton is considered because k+ ions has been used.
W= 0 - ( - 70. 5 mV) × 1.602 * 10^-19 C.
W= 8.18 × 10 ⁻²¹J.
Thus, the answer is 8.18 × 10 ⁻²¹.
