The answer is a, series circuit.
Answer:
a)q= 2800 W/m²
b)To=59.4°C
Explanation:
Given that
L = 10 mm
K= 20 W/m·K
T=30°C
h= 100 W/m²K
Ti=58°C
a)
Heat flux q
q= h ΔT
q= 100 x (58 - 30 )
q= 2800 W/m²
b)
As we know that heat transfer by Fourier law given as
Q= K A ΔT/L
Lets take outer temperature is To
So by Fourier law
To= Ti + qL/K
Now by putting the values
To= Ti + qL/K

To=59.4°C
Imagine an incline of length "x". You let the toy go at the top of the incline and measure the time "t" it takes for it to get to the bottom.
The average speed would be "v=x/t".
That’s kinda messed up ⬆️
