Answer:

Ve=12876.43mL  : Ethanol volume

Explanation:

We apply the formula to calculate the density:

ρ=\frac{m}{V} Formula (1)

Where:

ρ:Density in g/mL

m: mass in g (grams)

V= Volume in ml (milliliters)

We know the following data:

1L= 1000mL

Vm=Volume of mercury:VHg=0.750 L*1000mL/L=750mL

ρ-m=Density of mercury =13.546 g/mL

ρ-e: density of ethanol is 0.789 g/mL

m_{m} =m_{e}

Development of the problem:

In formula 1 We replace the known data for the  mercury :

ρ-m=\frac{m_{m} }{V_{m} }

13.546 \frac{g}{mL} =\frac{m_{m} }{750mL}

m_{m}=13.546 \frac{g}{mL}*750mL

m_{m} =10159.5 g

We know that m_{e} =m_{m} =10159.5 g, then, We replace the known data for the  ethanol In formula 1:

ρ-e=\frac{m_{e} }{V_{e} }

0.789 \frac{g}{mL} =\frac{10159.5g}{V_{e} }

Ve=\frac{10159.5 g}{0.789 \frac{g}{mL}}

Ve=12876.43mL

A material that transmits nearly all the light in a ray because it offers little resistance to the light is ________.
Nina [5.8K]

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.

leonid [27]

Answer:24.47

Explanation:

Given

L_1=30 m

d_1=3 mm

R_1=25 \Omega

L_2=40 m

d_2=3.5 mm

we know Resistance R=\frac{\rho L}{A}

Where R=resistance

\rho =resistivity

L=Length

A=area of cross-section

A=\frac{\pi d^2}{4}

Thus R\propto \frac{L}{d^2}

therefore

R_1\propto \frac{L_1}{d_1^2}--------1

R_2\propto \frac{L_2}{d_2^2}--------2

divide 1 and 2 we get

\frac{R_1}{R_2}=\frac{L_1}{L_2}\times \frac{d_2^2}{d_1^2}

\frac{R_1}{R_2}=\frac{30}{40}\times \frac{3.5^2}{3^2}

R_2=25\times 0.734\times 1.33

R_2=24.47 \Omega
