Explanation:
The given data is as follows.
Heat transfer coefficient (h) = 12
Plate temperature (
) = 
= 303 K
Steady state temperature (
) = ?
Hence, formula applied for steady state is as follows.
= 
Putting the given values into the above formula as follows.
=
= ![5.67 \times 10^{-8} \times [(30 + 273)^{4} - T^{4}_{2}]](https://tex.z-dn.net/?f=5.67%20%5Ctimes%2010%5E%7B-8%7D%20%5Ctimes%20%5B%2830%20%2B%20273%29%5E%7B4%7D%20-%20T%5E%7B4%7D_%7B2%7D%5D)
= 282.66 K
= (282.66 -273)
= 9.66
Thus, we can conclude that the steady state temperature will be 9.66 .
Answer:
The Sun and the planets were born from a cloud of gas and dust called the solar nebula 4.6 billion years ago. The collapse of the solar nebula was most likely triggered by a shock wave from a nearby supernova explosion. The Sun formed in the center, with the planets surrounding it in a thin disk.

Answer:
Vapour pressure of cyclohexane at 50°C is 490torr
Vapour pressure of benzene at 50°C is 90torr
Explanation:
Using Raoult's law, pressure of a solution is defined by the sum of the product sbetween mole fraction of both solvents and pressure of pure solvents.
In the first solution:
<em>(1)</em>
For the second equation:
<em>(2)</em>
Replacing (2) in (1):
-122.5torr = -0.250P°A
<em>Vapour pressure of cyclohexane at 50°C is 490torr</em>
And for benzene:
<em>Vapour pressure of benzene at 50°C is 90torr</em>
Answer:
true because of the elements
Answer: An alpha-particle is identical to the nucleus of a normal (atomic mass four) helium atom i.e. a doubly ionised helium atom. Alpha particles (also termed alpha radiation or alpha rays) was the first nuclear radiation to be discovered, beta particles and gamma rays were identified soon after.
