<span>THE AREA OF THE ROOM IS :A=4*2.4=9.6 m^2
THICKNESS t=0.30 m
DIFFERENCE IN TEMPERATURE dT=18-6=12
q=kAdT/dx=kA*dT/t
q=1.3(9.6)(12)/0.30=4992 W=499.2 J/s
In 1 hour or 3600 sec
P=q*T=(499.2 J/s)(3600 s)=1797120 J=1.8 MJ
1.8MJ OF HEAT FLOWS HTROUGH THE WALL IN ONE HOUR</span>
Answer:
the would be m=4
Step-by-step explanation:
Answer:
Choice C
Step-by-step explanation:
You can see the inequality symbol is not an equal to type so the circle is not closed
p is supposed to be bigger
goes to the right, Choice C
Answer:
g(x)=2x^2
Step-by-step explanation:
If you look at (1,1) for the blue function then (2,2) for g(x), you can kind of see that it is scaled by 2 (meaning its just twice as big). In another case you can see the blue function passing through (2,4), which matches with the point given to you for g(x), (4,8), which is twice as big.
Try b im about 80% sure thats right sorry if its wrong
