Answer:
86 mm
Explanation:
From the attached thermal circuit diagram, equation for i-nodes will be
Equation 1
Similarly, the equation for outer node “o” will be
Equation 2
The conventive thermal resistance in i-node will be
Equation 3
The conventive hermal resistance per unit area is
Equation 4
The conductive thermal resistance per unit area is
Equation 5
Since
is given as 100,
is 40
is 300
is 25
Substituting the values in equations 3,4 and 5 into equations 1 and 2 we obtain
Equation 6
Equation 7
From equation 6 we can substitute wherever there’s
with 3000L+40 as seen in equation 7 hence we obtain
The above can be simplified to be
-3000L=1.665-260
Therefore, insulation thickness is 86mm
Answer:
yes, the recordings sound is same
Explanation:
given data
recording done = 2 performances
1st show = sold out
2nd show = lightly attended
to find out
recordings sound the same and why
solution
as per given in
- 1st show is sold out it mean in this case concert hall is full so that recording sound should be high here
- 2nd case only few people are attended and struggle for ticket and orchestra
it mean it sound performance so in both case recording sound will be same
because we do not other all are sitting at front row or they sit as they want

Answer:
The following table is among some of the discrepancies between some of the different topics.
Explanation:
- Science seems to be the application of structured organized facts which could be interpreted scientifically because when engineering would be a branch of science which deals with either the profession of acquiring including using technological, computational, economical and severity of adverse effects to design and manufacture equipment and devices that seem to be beneficial to mankind.
- Science would be a set of information and established frameworks whereas the use of these models and information to construct structures as well as mechanisms becomes engineering.
Answer & Explanation:
"The force <em>on a cutting tool</em> are 2600N vertically downward" sounds a little unusual, since most of the time, the tool is above the object to be cut in such a way that the force acting "ON the tool" is upwards. We will accept the statement as it is (downwards).
Since the two forces are acting at right angles to each other, the resultant can be found using Pythagoras theorem, namely
resultant = sqrt(2600^2+2100^2) = 3342 N (approx.)
The angle can be found using the arcTangent function, or
angle = arcTangent(2600/2100) = 51.07 degrees below the horizontal, since the 2600 N force is acting downwards.
