Answer:
its surface temperature = 54.84 ° C
Explanation:
The density of aluminium = 2700 kg/m ³
Heat capacity = 897 J/Kg.K
radius of the sphere (r) = 0.081029 m
= 25 °C
= 124.978 °C
time (t) = 767.276 s
Using the formula :
where.
Replacing our values ;we have:
T ≅ 54.84 ° C
Therefore, its surface temperature = 54.84 ° C
The electric field between the plates is equal to the potential difference across the plates divided by the separation of the plates.
The potential difference across the plates is equal to the charge stored divided by the capacitance.
