Answer:

D. transparent.

Explanation:

A material that transmits nearly all the light in a ray because it offers little resistance to the light is <u>transparent.</u>

A transparent material allows light to pass through them with little or no resistance enabling them see-through. A material that transmits nearly all the light rays that pass through it because it offers little resistance to the light is TRANSPARENT. Examples of transparent materials are water, glass (flint and crown), air, and diamond.

larisa86 [58]

Technician a says that a defective spark plug wire can cause an engine misfire. Technician b says that a defective spark plug can cause an engine misfire. In this case, both technicians are correct.

Technician A is correct, because, Bad spark plug wires can interfere with the electrical current flowing to the engine, making it difficult for the engine to complete the combustion cycle. An incomplete combustion cycle can cause an engine to misfire, also

Technician B is correct because, Dirty spark plugs can cause misfires as well as burned engine oil can prevent the plugs from creating the sparks needed to ignite the fuel after it goes into the cylinder. Old spark plugs can simply break and fail to produce a spark. A broken spark plug is a simple fix, just replace it.

An RLC circuit with R = 23.5 Ω , L = 396 mH , and C = 49.5 μF is connected to an ac generator with an rms voltage of 29 V . (Par

Luden [163]

Answer:

power is 35.5 W

power is 1.06 W

Explanation:

Given data

R = 23.5 Ω

L = 396 mH

C = 49.5 μF

voltage = 29 V

solution

we know that in 1st part power that is equal to square of current × R

power = I²R

so current I = V/Z = 29/23.5 because R = Z at resonance

current = 1.23 A

power = 1.23²×23.5

power = 35.5 W

and

in 2nd part we know that frequency that is

f = 1/2π × √(1/LC)

f = 1/2(3.14) × √(1/396×10^-3×49.5×10^-6)

f = 35.94 Hz

so power = I²R

here

I = V/Z

Z = √( R² + (x - y)²)

x = 2π(2f) L

x = 2(3.14)× ( 2×35.94)×( 396× $10^{-3}$

x = 178.84 ohm

y = 1 / 2π(2f) C

y = 1 / 2(3.14)× ( 2×35.94)×( 49.5× $10^{-6}$

y = 44.73 ohm

Z = √( 23.5² + (178.84 - 44.73)²)

Z = 136.15 ohm

so current = 29 / 136.15

current I = 0.212 A

so power = 0.212² / 136.15

power = 1.06 W

and

in 3rd part same like 2nd

frequency = 35.94 Hz and X = 2π(2f) L = 2(3.14)× ( 35.94/2)×( 396× $10^{-3}$

X = 44.71 ohm

Y = 1 / 2π(2f) C = 1 / 2(3.14)× ( 35.94/2)×( 49.5× $10^{-6}$

Y = 178.98 ohm

so Z = √( 23.5² + (44.71 - 178.98)²)

Z = 136.25 ohm

current = 29 / 136.25

current = 0.212 A

so power = 0.212² / 136.15

power = 1.06 W
