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

The manager of a fashionable restaurant open Wednesday through Saturday says that the restaurant does about 29 percent of its bu
RideAnS [48]

Answer: The seasonal relatives is calculated are as follows:

Step-by-step explanation:

Given that,

restaurant only open from Wednesday to Saturday,

  • 29 percent of its business on Friday
  • 31 percent on Saturday night
  • 21 percent on Thursday night.

∴ The remaining 19% of its business he does on Wednesday

Now, suppose that total production of sales in a given week be 'y'

So, average sales in a week = \frac{y}{4}

If we assume that y = 1

hence, average sales in a week = \frac{1}{4}

= 0.25

Now, we have to calculate the seasonal relatives,

that is,

=  \frac{Sales in a given day}{average sales in a week}

Wednesday:

= \frac{0.19}{0.25}

= 0.76

Thursday:

= \frac{0.21}{0.25}

= 0.84

Friday:

= \frac{0.29}{0.25}

= 1.16

Saturday:

= \frac{0.31}{0.25}

= 1.24
