Answer:
0.84 Ω
Explanation:
r = mean radius of the turn = 6.5 mm
n = number of turns of copper wire = 150
Total length of wire containing all the turns is given as
L = 2πnr
L = 2 (3.14)(150) (6.5)
L = 6123 mm
L = 6.123 m
d = diameter of the wire = 0.4 mm = 0.4 x 10⁻³ m
Area of cross-section of the wire is given as
A = (0.25) πd²
A = (0.25) (3.14) (0.4 x 10⁻³)²
A = 1.256 x 10⁻⁷ m²
ρ = resistivity of copper = 1.72 x 10⁻⁸ Ω-m
Resistance of the coil is given as
R = 0.84 Ω

Answer:
Magnetic field at the center will be 
Explanation:
We have given that diameter of the loop d = 14 cm = 0.14 m
So radius 
Current in the loop i = 2.40
We know that magnetic field at center of circular loop is given by
So 
Magnetic field at the center will be
Answer:
make sure there spreaded out
Explanation:
<em>you have to spread them out because you dont want one half to be dry and the other side wet and if theres some that are white and some that are colored the color can bleed so yea spread hem out</em>
