Idk what it means.why is it not reasonable to say that 4.23 is less than 4.135
RSB [31]

it is unreasonable because 4.23 is bigger than 4.135! Look at the 10s place - 1 is smaller than 2, and everything afterwards is irrelevant. There could be as many zeros or any combination of numbers you want, but as long as that tens place is larger (2 vs 1), than it's not reasonable to say 4.2 is smaller!!

-BARSIC- [3]

Answer:

K-a Positive constant that depends on the area and nature of the surface of the body under consideration.

Step-by-step explanation:

Newtons law cooling describes the rate at which an exposed body changes temperature through radiation which is approximately proportional to the difference between the object’s temperature and its surroundings, provided the difference is small. The formula is given as:

\frac{dT}{dt}=k(T-T_m)

where,T- temperature at time t,T_m is temperature of the surrounding and k- A Positive constant that depends on the area and nature of the surface of the body under consideration.
