Answer:
1. 2.5 mm
2. 0.25 cm
Explanation:
Since the length of the 10 turns of the wire around the pencil is 25 mm, then;
1. the thickness of the wire = 
= 
= 2.5 mm
The thickness of the wire is 2.5 mm.
2. Since 10 mm = 1 cm, then;
25 mm = 2.5 cm
So that,
the thickness of the wire in centimetre =
= 
= 0.25 cm
The thickness of the wire is 0.25 cm.
Nuclear Fusion is hopefully the answer to your question.
The current in the junction is 1350 mA or 1.350 A.
Explanation:
As per Kirchoff's first law, the algebraic sum of current meeting at any junction should be equal to the algebraic sum of current leaving the junction. As in the present case, three parallel branch circuit is given the current in 250 mA, 300 mA and 800 mA, respectively, the sum of these three current will be equal to the current in the junction.
So,
I₁+I₂+I₃ = I₄
So I₁,I₂ and I₃ are the current passed in the three parallel branches and I₄ is the current in the junction.
250 + 300 + 800 = 1350 mA
So the current in the junction is 1350 mA or 1.350 A.
