The passing of heat through a material while the material itself stays in place is conduction.
Answer:
Value of 
Explanation:
We have given
In first case resistance is
and current is 1.8 A
Let the potential difference is v
So
----eqn 1
In second case resistance is
and current is 1.6 A and potential difference will be as it is a series connection
So
----eqn 2
From eqn 1 and eqn 2


True, nuclear reactions, whether they are fission or fusion depend on generating energy by converting a certain amount of mass by breaking the atom or combining two atoms together.
