What is flux?</h3>
Flux describes any effect that appears to pass or travel through a surface or substance.
The magnitude and direction (inward or outward) of the net flux through the cell boundary is calculated as follows;
Ф = Q/ε
where;
- Q is net charge
- ε is permittivity of free space
Φ = (-7.85 x 10⁻¹²)/(8.85 x 10⁻¹²)
Φ = - 0.887 wb.m²

Circularity system........…….......
it would be a chain reaction and a wave
the answer is b) magnetic current
Answer:
Explanation:
Near point = 56 cm .
near point of healthy person = 25 cm
person suffers from long sightedness
convex lens will be required .
object distance u = 25 cm
image distance v = 56 cm
both will be negative as both are in front of the lens.
lens formula
I/v - 1 / u = 1/f
- 1/56 +1/25 = 1/f
- .01785 + .04 = 1/f
1/f = .02215
f = 45.15 cm .
