3 identical dry cells each
of e. m.f. 1.6 V are connected in a series to a resistor of 11.4 ohms. A current of 0.32A flows in the circuit. Determine:
a) the total em. f of the cell
b) the internal resistance of each cell.​

the plateau is likely to turn into a desert do to corrosion.

a longitudinal wave moves energy that is to the direction of the wave’s movement. - true

the answer would be 32*f

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
