The cooling rate of the substance is approximately 0.0732.
According to the statement, the Newton's law of cooling is defined by the following formula:
(1)
Where:
- Final temperature, in degrees Celsius.
- Initial temperature, in degrees Celsius.
- Time, in minutes.
- Cooling rate, in
.
- Current temperature, in degrees Celsius.
Please notice that substance reaches thermal equilibrium when
, that is when temperature of the substance is equal to the temperature of surrounding air.
If we know that
,
,
and
, then the cooling rate of the substance is:





The cooling rate of the substance is approximately 0.0732.

Answer:
10.296
Explanation:
From point A to point B, the line goes 5 spaces to the left and 9 spaces down. You can use the Pythagorean theorem and solve for the c value. 5 squared is 25, 9 squared is 81, 25 + 81 = 106. The square root of 106 is approximately 10.296. Hope that helped
