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

An experiment consist of rolling 3 fair dice (1 red die, a blue die, and a white die) and recording the number rolled on each di
Setler79 [48]
In 1, t<span>here are 6 outcomes for each die, so for three dice, the total combination is 6 x 6 x 6 = 216 outcomes. Hence, t</span><span>he probability of any individual outcome is 1/216 </span>

The outcomes that will add up to 6 are 
<span>1+1+4 </span>
<span>1+4+1 </span>
<span>4+1+1 </span>
<span>1+2+3 </span>
<span>1+3+2 </span>
<span>2+1+3 </span>
<span>2+3+1 </span>
<span>3+1+2 </span>
<span>3+2+1 </span>
<span>2+2+2 </span>

<span>Hence the probability is </span><span>10/216 </span>

In 3, the minimum sum of the three dice is 3. so we start with this 
<span>P(n = 3) </span>
<span>1+1+1 ; </span><span>1/216 </span>

<span>P(n = 4) </span>
<span>1+1+2 </span>
<span>1+2+1 </span>
<span>2+1+1 ; </span><span>3/216 </span>

<span>P(n = 5) </span>
<span>1+1+3 </span>
<span>1+3+1 </span>
<span>3+1+1 </span>
<span>1+2+2 </span>
<span>2+1+2 </span>
<span>2+2+1; </span><span>6/216 

The sum in 3 is 10/216 or 5/108</span>
