Calculate the resistance of a 270-cm length of copper wire with a 0.030-cm2 cross-sectional area. ( = 1.8 · 10-6 ohm-cm) R = ___
devlian [24]

Answer:

Given:-

The length of copper wire (L) = 270 cm

Area of cross-sectional (A) = 0.030 cm^2

and specific resistance (ρ) = 1.8 \times 10^{-6} ohm-cm.

Use the formula  R=(Specific resistance*L)/A, to calculate the Resistance(R)

then, R=\frac{1.8 \times 10^{-6} \times 270}{0.030} ohm

Simplify:

R = 0.0162 ohm = 1.62\times 10^{-2} ohm

Therefore, the resistance of copper wire is,  1.62\times 10^{-2} Ω

Each car in a rental fleet is either red or white, and there are 75 cars total. There are three more white than twice the number
professor190 [17]
Number of red cars = x
Number of white cars = y

x + y = 75
y + 3 = 2x

x + y = 75
y = 75 - x

(75 - x) + 3 = 2x
78 = 3x
26 = x

y + 3 = 2(26)
y + 3 = 52
y = 49

There are 49 white cars.

Which property of equality can be used to solve the equation n plus nine equals negative three?
aksik [14]

Answer: Subtraction property of equality.

Step-by-step explanation:

n + 9 = -3

You are trying to move 9 from one side to the other. To do that, you have to do the <em>inverse operation</em> and <u>subtract</u> nine from both sides. Your result would be n = -12.
