An aluminum rod 0.500 m in length and with a cross-sectional area of 2.20 cm2 is inserted into a thermally insulated vessel cont
netineya [11]

Answer:

a). V_{He}   = 14.6208 litres : b). = 0.29844 Litres/sec

Step-by-step explanation:

a).

Step 1.

Volume when one half of rod is inserted = (50/2)*(2.2) = 55cm³

Step 2.

As we know that,

V_{He} = (ρV_{c}IΔT)_{Al} / (ρL_{v})H_{c}                     where H_{c} = 290 - 4.2 = 285.8K

                                                        sepecififc heat of aluminum = 0.215 cal/g

                                                                                      density = 2.7 g/cm3

      = (2.7)*(55)*(0.215)*(285.8) / (0.125)*(20900)*(1/4186)

V_{He}   = 14.6208 litres

b).

Step 1.

As we know that

  P = kA(dT/dx) = 31*2.2*[(290-4.2)/25]

                         = 779.6624 W

Step 2.

Now, approximate boil rate of helium is:

P/ρL_{v}= [(779.6624)*(10^3g/kg)] / [(0.125)*(20900)]

         = 0.29844 Litres/sec

What is the value of m ? 2(3 m - 6 + 3 m) = 2 m + 2 -4 m
gulaghasi [49]
2(3m-6+3m)=2m+2-4m
6m-12+6m=2m+2-4m
12m-12=-2m+2
14m-12=2
14m=14
m=1

Given that the measurement is in centimeters, find the area of the circle to the nearest tenth. (Use 3.14 for π)
kvv77 [185]

Answer:

Option D) 254.3 cm2

Step-by-step explanation:

we know that

The area of a circle is equal to

A=\pi r^{2}

we have

r=9\ cm

substitute

A=(3.14)(9)^{2}=254.3\ cm^2
