Answer:
An attachment follows below
Explanation:
1) The formula used for the damping coefficient in a series RLC circuit.
If \xi = 0, it is possible to set c = 0 but an inductor will still possess some capacitance.
2) The behaviors of critically damped and underdamped systems are illustrated along with comments on their temporal responses.
4) While several answers might suffice, the four I’ve highlighted are the crucial parameters necessary about an unknown op-amp before utilizing it in a circuit.
Hope this addresses all your inquiries.
It is not feasible to install the wires within the conduit. Explanation: The given dimensions show that the total area is 2.04 square inches while the wires occupy 0.93 square inches. The maximum allowable fill for the conduit is 40%. To determine if placement is possible, compute the conduit’s area at 40% which equates to 0.816 square inches, less than the required area of the wires.
Answer:
Explanation:
The half-life for the specified RC circuit can be expressed as
where [/tex]\tau = RC[/tex]
Given 
The circuit has a resistance of 40 ohms, and by adding a new resistor of 48 ohms, the total resistance becomes 40 + 48 = 88 ohms.
Thus, the new half-life is
Now, divide equation 2 by 1
After substituting all values, we can calculate the revised half-life
Answer:
t = 5.27 years
Explanation:
Firstly, the corrosion penetration rate is defined by the formula;
CPR = (KW)/(ρAt)
Where;
K = constant based on exposed area A.
W - mass lost over time
t- duration
ρ - density
A - area exposed
From the problem, we have;
W = 7.6kg or 7.6 x 10^(6) mg
CPR = 4 mm/yr
ρ = 4.5 g/cm³
Area = 800 cm²
K is a constant valued at 87.6cm
Rearranging the CPR formula to isolate t, we derive;
t = KW/(ρA(CPR))
t = (87.6 x 7.6 x 10^(6))/(4.5 x 800 x 4) = 46233.3 hours
The duration in question needs to be expressed in years.
Thus, converting hours to years;
There are 8760 hours in a year.
Therefore;
t = 46233.3/8760 = 5.27 years.
In the scenario of a metal ingot cooling slowly, the microstructure tends to be coarse. The surface, exposed to higher temperatures for extended periods during cooling, features smaller grain sizes as they have less time to form. However, as we delve deeper into the ingot, the grains gradually extend, leading to equiaxed grain formation at the center.
