17. what meant by letter T in the THHN wire?
Answer:
thermoplastic,
Explanation:
T is for thermoplastic, H is for 75°C, HH is for 90°C, N is for nylon jacket, W is for wet location, X is for crosslinked polyethylene, and R is for rubber. Therefore, THWN is thermoplastic insulation, 75°C rated, wet location and a nylon jacket. THHN is thermoplastic insulation, 90°C rated, dry location, nylon jacket.

[tex]\rm\huge{ANSWER:}[/tex]
[tex]_________________________[/tex]
Question :3. Find the surface area of spherical ball whose radius is 6 mm.
Choices :a. 452.16 mm²
b. 425.61 mm²
c.245.16 mm²
d. 524.61 mm²
ANSWER AND SOLUTION :Use this formula SA= 4 πr² to get the Surface Area.
SA = 4 πr²
= 4 × 3.14 ×( 6mm)²
= 4 × 3.14 × 36 mm²
= 452.16 mm²
✒️ Therefore, the surface area of the ball is A. 452.16 mm².
30. A metallic wire is stretched from original length of 3 m to 6 m. If the original cross-sectional area is 4 mm2 and original resistance is 6 Ω, determine the new resistance of the metallic wire.
Answer:
The new resistance of the metallic wire is 24Ω
Explanation:
In this problem, we will use the concept of electrical resistivity and resistance of the metallic wire.
Formula to use
R = ρL/ A
where
ρ is the electrical resistivity of the wire, the unit is in Ω-m
L is the length of the wire, the unit is in meter
A is the cross-sectional area of the wire, the unit is in m²
Given information
R = 6Ω R(new) = ?
L = 3m L(new) = 6m
A = 4mm² = 4 x 10⁻⁶ m² A(new) = 1/2(4 x 10⁻⁶ m²) = 2 x 10⁻⁶ m²
Take note that, the length from 3m becomes 6m. This means that the length of the wire is doubled. So, when the length is doubled, the area of the wire becomes half. That is why the new value for the area is 2 x 10⁻⁶ m².
Solving the problem
a. Let us solve first the resistivity of the wire using the given formula for resistance and substitute the given data.
R = ρL/ A
6Ω = ρ(3m)/ 4 x 10⁻⁶ m²
Cross-multiply
ρ = [tex]\frac{(6\Omega)(4x10^{-6}m^2)}{3m}[/tex]
ρ = 8 x 10⁻⁶ Ω-m
b. Let us solve the new resistance of the metallic wire using the same formula and substitute the given data.
R(new) = ρL(new)/ A(new)
R(new) = (8 x 10⁻⁶ Ω-m)(6m) / 2 x 10⁻⁶ m²
Take note that we use the same electrical resistivity because it is the same material and it does not change with dimensions.
Then, simplify the equation
R(new) = 24Ω
Therefore, the new resistance of the metallic wire is 24Ω.
