Ajet has a mass of 4 kilograms the thrush pushing force of each of the four engines is 2 newtons what is the jets acceleration when taking off​

as we know that in transformers we have

here we know that

now from above equation we will have

now we have to reduce this voltage to final voltage of v = 4 v

so again we will have

so we need to take such a winding whose ratio is 1: 5

so it is satisfied in x

so answer will be

b)-   x

speed = (change in distance) / (time for the change)

distance from top to bottom of segment c = (6 - 0) = 6 m

time from beginning to end of segment c = (14 - 4) = 10 s

speed = (6 m) / (10 s)

speed = 6 m/s
