Two resistors of 10 ohm and 15 ohm are to be connected to a battery of 10 v to obtain minimun current and maximum current a how will you connect the resistors in each case

Minimum current:

Connectum in series.

Get 0.4 Ampere.

Maximum current:

Puttum in parallel.

Get 1.67 Ampere.

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
