Step-by-step explanation:
What is the mathematical representation of joules law of heating
What is joules law of heating ??
Joule’s law is a mathematical description of the rate at which resistance in a circuit converts electric energy into heat energy.
Mathematically
Q = I^2 R T
Where,
Q indicates the amount of heat
I show electric current
R is the amount of electric resistance in the conductor
T denotes time
Answer:
The area of the room and its uncertainty in square meters is:
15.642±0.040 
Step-by-step explanation:
We know the area of a rectangular room is the multiplication of the length and width:
Now we need to know the uncertainty, the uncertainty of a multiplication is:
(1)
: Area uncertainty
: Length uncertainty
: Width uncertainty
A: Area of the room
L: Length
W: Width
Clearing the uncertainty of the area:
(2)
The area of the room and its uncertainty in square meters is:
15.642±0.040
