Answer:
the rate of heat loss is 2.037152 W
Explanation:
Given data
stainless steel K = 16 W 
diameter (d1) = 10 cm
so radius (r1) = 10 /2 = 5 cm = 5 × 
radius (r2) = 0.2 + 5 = 5.2 cm = 5.2 × 
temperature = 25°C
surface heat transfer coefficient = 6 6 W 
outside air temperature = 15°C
To find out
the rate of heat loss
Solution
we know current is pass in series from temperature = 25°C to 15°C
first pass through through resistance R1 i.e.
R1 = ( r2 - r1 ) / 4
× r1 × r2 × K
R1 = ( 5.2 - 5 )
/ 4
× 5 × 5.2 × 16 × 
R1 = 3.825 ×
same like we calculate for resistance R2 we know i.e.
R2 = 1 / ( h × area )
here area = 4
r2²
area = 4
(5.2 ×
)² = 0.033979
so R2 = 1 / ( h × area ) = 1 / ( 6 × 0.033979 )
R2 = 4.90499
now we calculate the heat flex rate by the initial and final temp and R1 and R2
i.e.
heat loss = T1 -T2 / R1 + R2
heat loss = 25 -15 / 3.825 ×
+ 4.90499
heat loss = 2.037152 W
Answer:
Zero.
Explanation:
Lets take velocity V is given as in 2 dimensional flow
V=u i +v j
V=f(x,y)
u=f(x,y)
v=f(x,y)
Rotational ability ω given as

If
ω=0 ,then flow will be irrotational.
ω ≠0 ,then flow will be rotational.
So we can say that , ω will be zero every where for irrotational two dimensional flow .

Answer:
Considering the plain view doctrine, which is an exception to the warrant requirement of the Fourth Amendment, is applied by law enforcement officers and courts who can seize evidence of a crime without a warrant, if the officer observes the evidence in plain view.
Explanation:
For any digital information related to a murder case that has been seized under the plain view doctrine to be used to convict you of a crime, has to comply with three conditions:
1. The digital evidence must be in out in the open, and easily observable by the officer, this is what "plain view" refers to.
2. The officer must have a legal right to be where he got the information related to the case.
3. The 'incriminating' character of the information must be a clear hint of the murder to fall under the plain view doctrine and the officer´s experience will help him determining whether the information is evidence or not, upon probable cause related to a crime.
Answer:
Vout= 93.3V
Explanation:
For this question, consider circuit in the attachment 1.
This is the circuit of an inverting amplifier. In an inverting amplifier
Vout/Vin= -Rf/Rin
To calculate the Vout, we must find Rin and Vin. For this we must solve the input circuit (attachment 2) using Thevinine theorem. Thevnine theorem states that all voltage sources in a circuit can be replaced by an equivalent voltage source Veq and and all resistances can be replaced by an equivalent resistance Req. To find out Req all voltage sources must be short circuited (attachment 3)
1/Req= 1/R1+1/R2+1/R3
1/Req=1/6+1/3+1/3
Req=6/5
To find out Veq consider circuit in attachment 4. We will solve this circuit using nodal analysis. In nodal analysis, we use the concept that sum of currents entering a node is equal to the sum of currents leaving a node. So,
I1= I2+I3
(10-Veq)/6= (Veq-5)/3+(Veq-10)/3
Veq=8V
Now the input circuit can be simplified as shown in attachment 5. Solve for Vout using equation
Vout/Veq= -Rf/Req
Vout/8= -14/(6/5)
Vout= - 93.3
It is at an angle of 180° from Veq
