Question

help plz...Using calculus and the equation you wrote in Activity 2, the team determined
that the temperature of an object....

Answer 1

dT/dt=-k(T-T_a)

Answer 2

T(t) 5 A 1 (T0 2 A)e2kt, where T0 represents the temperature at time t 5 0. Verify that
the constant of variation can be found by using the formula k 5 21
t1
ln Q
T1 2 A
T0 2 AR, where
T1 represents the temperature at some later time t1. Th en, verify that tn, the
time the engine stopped running at a normal operating temperature, is given by
tn 5 21
k
ln Q
Tn 2 A
To 2 AR, where Tn represents the normal operating temperature of the engine
