Answer:
y = x - 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (2, 0) and (x₂, y₂ ) = (0, - 1) ← coordinates of intercepts
m = =
=
The y- intercept is - 1 ⇒ c = - 1
y = x - 1
Answer:
Given:-
The length of copper wire (L) = 270 cm
Area of cross-sectional (A) = 0.030
and specific resistance (ρ) = ohm-cm.
Use the formula R=(Specific resistance*L)/A, to calculate the Resistance(R)
then, ohm
Simplify:
R = 0.0162 ohm = ohm
Therefore, the resistance of copper wire is, Ω
