Newton's law of cooling states that the temperature of an object changes at a rate proportional to the difference between its te
Eva8 [605]

Answer:

Step-by-step explanation:

As per Newton law of cooling we have temperature of a cooling object at time t is given by

T(t) = T_s + (T_0-T_s) e^{-kt}

where T_s = 76:   T_0 = 200

When t=2.5, we have

T(2.5) = 76+(100-76)e^{-2.5k} =180\\e^{-2.5k} =\frac{104}{24} =4.333\\k=\frac{ln4.333}{-2.5} =-0.5865

Hence equation is

T(t) = 76+24e^{-0.5865t}

Using this we find that

130=76+24e^{-0.5862t} \\e^{-0.5862t}=54\\t=1.59559

i.e. At 1.6 seconds the coffee will reach a temperature of 130 degrees

dem82 [27]
Dr.hong prescribed the lest and Dr.evans prescribed the most. that is the answer but this is how i got the answer ok so you see that hong gave 0.019 that is not at all the same as 0.02 so you would add a zero to Evans so it would be 0.020 so it is the same length of hongs so now do you know how i got that if not then message me
