Answer:
“I really love the design work in engineering, the face-to-face interaction with clients, and the opportunity to see projects come to life. But if I had to pick one thing that I don’t enjoy as much, I would have to say it’s contract preparation.”
Answer:
36V, 100A-hr
Explanation:
Since the batteries are connected in series;
i. the output voltage will be the sum of the individual voltages
ii. the current rating (A-hr) will be the same as their individual current rating (A-hr). And this is because the same current flows through the batteries.
From i,
The output voltage, V, is given by the sum of the voltages of the three batteries;
V = 12V + 12V + 12V
V = 36V
From ii,
The A-hr capacity of the connection is the same as that of the individual batteries;
100 A-hr
Therefore, the output voltage and A-hr capacity of this connection is:
36V, 100A-hr
Answer:
The final pressure is 3.16 torr
Solution:
As per the question:
The reduced pressure after drop in it, P' = 3 torr = 
At the end of pumping, temperature of air, 
After the rise in the air temperature, 
Now, we know the ideal gas eqn:
PV = mRT
So
(1)
where
P = Pressure
V = Volume
R = Rydberg's constant
T = Temperature
Using eqn (1):
Now, at constant volume the final pressure, P' is given by:
