v = 80.48 km/h.

Explanation:

We have,

Acceleration of a train is 2 km/h/s or 7200 km/h²

Initial velocity of a train is 20 km/h

It is required to find the velocity after 30 seconds or 0.0084 h

Let v is the final speed. Using equation of kinematics as :

So, the final speed of the train is 80.48 km/h.

when the use of electricity burdens the fuse and miniarure circuit beakers and there is a possibility of a fuse then they automatically cut off the electricity supply to your homes and after you fix the problem u jzt switch it on and it continues the supply of electricity to ur homes
