The electrons are already there. They are freely moving through the conductor.
Avg acceleration; under constant acceleration condition only; = Vf-Vi/time
a=Vf-Vi/time=(15m/s-6m/s)/(3s)=
(9m/s)/(3s)=3m/s^2
Hope this helps. Thanks.

Answer:
The kinetic energy of the particle will be 12U₀
Explanation:
Given that,
A particle is launched from point B with an initial velocity and reaches point A having gained U₀ joules of kinetic energy.
Constant force = 12F
According to question,
The kinetic energy is
....(I)
Constant force = 12F
A resistive force field is now set up ,
Resistive force is given by,
When the particle moves from point B to point A then,
We need to calculate the kinetic energy
Using formula for kinetic energy
Put the value of
Now, from equation (I)
Hence, The kinetic energy of the particle will be 12U₀.
Answer:
the time required is 0.886 seconds
Explanation:
The computation is shown below:
As we know that the content of the chemical energy that has a calorific value of hydrogen is 141790 kJ /kg
And, the total energy stores is 100,000 kg
Now
E = 141790 × 100,000 kJ
= 14.179 TJ
The time would be
T = E ÷ P
= 14.179 ÷ 16
= 0.886 sec
hence the time required is 0.886 seconds
