Answer:
ΔU =195 KJ
W=0 KJ
Explanation:
Given that
Mass of air m=3 kg
heat absorb by air =195 KJ
Cv=0.741 KJ/kgK
If we assume that air is as ideal gas so
Given that container is rigid it means that volume of system is constant so W=0
From first law of thermodynamics
Q=ΔU + W
⇒Q= ΔU (W=0)
So ΔU =195 KJ
And work done will be zero because because it is a constant volume process.
Answer:
C. 14.55
Explanation:
12 x 10 = 120
120 divded by 10 is 12
so now we do the left side
7 x 3 = 21 divded by 10 is 2
so now we have 14
and the remaning area is 0.55
so 14.55
Given Information:
Current of Ideal source = Is = 100 mA = 0.100 A
Open circuit voltage = Voc = 6 V
Short circuit current = Isc = 200 mA = 0.200 A
Required Information:
Power absorbed by idea current source = ?
Answer:
Power absorbed by idea current source = 0.3 Watts
Explanation:
Ideal Current Source:
An ideal current source doesn't have internal resistance and provides constant current regardless of the voltage supplied to the circuit.
The power absorbed by the ideal source can be found using
P = Is²R
Where Is is the ideal source current and R can be found using
R = Voc/Isc
Where Voc is the open circuit voltage and Isc is the short circuit current.
R = 6/0.200
R = 30 Ω
Therefore, the power absorbed by the ideal current source is
P = Is²R
P = (0.100)²*30
P = 0.3 Watts

you should probably take it
Explanation:
An extended vehicle warranty typically starts once the manufacturer's warranty expires, but in some cases, the two protection plans overlap.
