Aplane dielectric slab of large face area a perpendicular to the x-axis has dielectric constant k(x), a general function ofx, between conducting plates carrying free charge of surface density fon their inner surfaces. (a) find d(x), e(x), and pc). (your formulas will be directly applicable in vacuum regions, with k(x) 1) (b) derive an integral formula for the capacitance; start by evaluating the potential difference between the plates from part (b). (c) check against the standard series circuit formula divide the slab into layers of infinitesimal reciprocal capacitance

attach the statements so i can answer : )

the minimum constant speed at which she can catch the train is 2.7 m/s

given:

acceleration = 0.6

time = 4.5 s

to find:

velocity = ?

formula used:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

solution:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

v = 0 + (0.6 × 4.5)

v = 2.7 m/s

the minimum constant speed at which she can catch the train is 2.7 m/s
