Answer:

By replacing your home's five most frequently used light fixtures or bulbs with models that have earned the ENERGY STAR, you can save $75 each year.

Compared to traditional incandescents, energy-efficient lightbulbs such as halogen incandescents, compact fluorescent lamps (CFLs), and light emitting diodes (LEDs) have the following advantages:

Typically use about 25%-80% less energy than traditional incandescents, saving you money

Can last 3-25 times longer.

A wire is hung between two towers and has a length of 208 m. A current of 154 A exists in the wire, and the potential difference
NARA [144]

Answer:

Mass = 4152kg

Explanation:

Given

L = 208m

I = 154A

V = 0.245V

Density = 3610 kg/m3

ρ = 4.23 x 10-8Ω·m = resistivity of wire

Resistance R = ρL/ A

R = voltage / current = V/I = 0.245/154 = 1.59×10-³ohms

1.59×10-³ = 4.23 x 10-⁸×208/A

Rearranging,

A = 4.23 x 10-⁸×208/1.59×10-³

A = 5.53×10-³m²

Mass = density × volume

Volume = L×A = 208×5.53×10-³m³= 1.15m³

Mass = 3610×1.15 = 4152kg

A metal disk of radius 6.0 cm is mounted on a frictionless axle. Current can flow through the axle out along the disk, to a slid
Galina-37 [17]

Answer:

0.09 N

Explanation:

We are given that

Radius of disk,r=6 cm=\frac{6}{100}=0.06 m

1 m=100 cm

B=1 T

Current,I=3 A

We have to find the frictional force at the rim between the stationary electrical contact and the rotating rim.

dF=IBdr

dF=IBdr

\tau=rdF=IBrdr

\tau=\int_{0}^{R}IBr dr

\tau=IB(\frac{R^2}{2}

Torque due to friction

\tau=R\times F

Where friction force=F

R\times F=\frac{IBR^2}{2}

F=\frac{IBR}{2}

Substitute the values

F=\frac{3\times 1\times 0.06}{2}

F=0.09 N
