An alternating current is supplied to an electronic component with a rating that the voltage across it can never, even for an instant, exceed 16 v. what is the highest rms voltage that can be supplied to this component while staying below the voltage limit?
a)8 sqrt 2 v

b) 16 sqrt 2 v

c) 256 v

d) 8

A)

Explanation:

Maximum voltage =

Maximum voltage and rms voltage are related to each other by

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
