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
Answer:
The parallel plate capacitor is the simplest form of capacitor. ... The property of a capacitor to store charge on its plates in the form of an electrostatic field is called the Capacitance of the capacitor. Not only that, but capacitance is also the property of a capacitor which resists the change of voltage across it.
