Answer and Explanation:
- Phase change as a function of the log of the frequency
The phase shift should be independent of the frequency of the input signal. It should have an Infinite bandwidth with zero phase shift
- Common Mode Rejection Ratio
An ideal amplifier has Infinite common-mode rejection ratio (CMRR). A perfect operational amplifier amplifies only the voltage difference between its two inputs, completely rejecting all voltages that are common to both.
- Input Resistance
Infinite input impedance and so, zero input current & Zero input offset voltage.
The differential input impedance of the operational amplifier is defined as the impedance between its two inputs; the common-mode input impedance is the impedance from each input to ground.
And the impedance between its inputs should be infinite.
- Output Resistance
Zero output impedance and Infinite output voltage range.
Output Resistance leads to voltage drop. Thee voltage drop across the output impedance effectively reduces the open loop gain. So, the optimal value for this should be zero.
N.B - For AC circuits such as this one being discussed, resistance is known as impedance.
Answer:
(a) water height =408.66 in.
(b) mercury height=30.04 in.
Explanation:
Given: P=14.769 psi ( 1 psi= 6894.76 
)
we know that 
where 
h=height.
Given that P=14.769 psi ⇒P= 101828.6 7
(a) 
⇒101828.67=
=10.38 m
So water barometer will read 408.66 in. (1 m=39.37 in)
(b) 
=13600
So 101828.67=
=0.763 m
So mercury barometer will read 30.04 in.
Answer:
(a) Calculate the rod base temperature (°C). = 299.86°C
(b) Determine the rod length (mm) for the case where the ratio of the heat transfer from a finite length fin to the heat transfer from a very long fin under the same conditions is 99 percent. = 0.4325m
