Answer:
-13.18°C
Explanation:
To solve this issue, we must examine the principles associated with the rate of thermal conduction.
This rate is defined by the equation
Where,
Q = Amount of heat transferred
t = time
k = Thermal conductivity constant
A = Area of cross-section
Temperature difference across the material
d = Material thickness
The scenario indicates a heat loss that is double the initial value, which means
Substituting values yields,
Solving for 
,
Thus, when the heat lost per second is doubled, the temperature on the external surface of the window is -13.18°C.
Reminder: The illustration mentioned in the inquiry is included here as a file.
Response:
The intensity of the magnetic field is 
Clarification:
The magnetic field can be calculated using the following equation:
...............(1)
Where I refers to the current flowing through the wires
To find the distance R from point 1 to m, apply the Pythagorean theorem
Inserting R into equation (1)
Fire extinguishers are commonly colored red, which aligns with the red of fire trucks and the general association of red with emergencies. Although there is no official standard, altering the colors could lead to confusion, potentially endangering lives. Therefore, it seems that red will likely remain the color of fire extinguishers for the foreseeable future.
