Answer:
The numbers are 50 & -72.
Step-by-step explanation:
Let the first number is x and the second number is y.
According to the question:-
x + y = -22 ........(1)
x - y = 122 ........(2)
By adding equation 1 & 2-
2 x = 100
x = 50
Put X =50 in equation (1)-
y = -22 -50
y = -72
Hence the numbers are (50, -72).
<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
