Answer:
Temperature distribution is 
Heat flux=q
Heat rate=q A
Explanation:
We know that for no heat generation and at steady state



a and are the constant.
Given that heat flux=q
We know that heat flux given as

From above we can say that

Alos given that when x= L temperature is T(L)=T


So temperature T(x)


So temperature distribution is 
Heat flux=q
Heat rate=q A (where A is the cross sectional area of wall)
Answer:
The maximum power dissipation of the zener diode 112mV.
Explanation:
The minimum zener current should be:
5 * Iza= 5 * 1= 5 mA.
Since the load current can be at maximum 15 mA, we should select R so that, IL= 15 mA.
A zener current of 5 mA is available, Thus the current should be 20 mA, which leads to,
R =
= 470 Ω.
Maximum power dissipated in the diode occours when, IL=0 is
Pmax = 20 *
* 5.6 = 112mV.
Answer: 0.053
Explanation:
So, we convert 5.3 grams into kilograms.
5.3g = 0.0053 kg (Since 1kg equals 1000g)
On Earth, gravity is 10 N/kg.
Weight = mass x gravity
Weight = 0.0053kg x 10 N/kg
Weight = 0.053 Newtons (On Earth)
