Answer:
Q = 62 ( since we are instructed not to include the units in the answer)
Explanation:
Given that:
Q = ???
Now the gas expands at constant pressure until its volume doubles
i.e if
Using Charles Law; since pressure is constant
mass of He =number of moles of He × molecular weight of He
mass of He = 3 kg × 4
mass of He = 12 kg
mass of Ar =number of moles of Ar × molecular weight of Ar
mass of He = 7 kg × 40
mass of He = 280 kg
Now; the amount of Heat Q transferred =
From gas table
∴ Q =
Q =
Q = 62 MJ
Q = 62 ( since we are instructed not to include the units in the answer)

Answer:
hello your question is incomplete attached below is the missing part of the question
Consider an inverter operating a power supply voltage VDD. Assume that matched condition for this inverter. Make the necessary assumptions to get to an answer for the following questions.
answer : Nd ∝ rt
Explanation:
Determine how the delay and active power per device will change as the doping density of N- and P-MOSFET increases
Pactive ( active power ) = Efs * F
Pactive =
also note that ; Pactive ∝ Nd2 (
tD = K . since K = constant
Hence : Nd ∝ rt
Answer:
a) The forward voltage is 0.23 V
b) The current that flows
Explanation:
The forward voltage is the minimum voltage that must be applied to a diode before it starts to conduct. The equation is given by:
a) At what forward voltage does a diode conduct a current equal to 10,000 Is ? In terms of Is
Where:
Id is the diode current = 10000Is,
Vd is the forward voltage at which the diode begins to conduct,
Is is the saturation current.
Dividing through by Is,
Taking the natural logarithm of both sides,
multiplying through by 0.025
= 0.23 V
The forward voltage does a diode conduct a current equal to 10,000 Is is 0.23 V
b) what current flows in the same diode when its forward voltage is 0.7 V?
