Answer:
t = 1456.8 sec
Explanation:
given data:
contant k = 2.60*10^{-6}
rate of crystallization is 0.0013 s-1
rate of transformation is given by
![r = \frac{1}{t_0.5}](https://tex.z-dn.net/?f=r%20%3D%20%5Cfrac%7B1%7D%7Bt_0.5%7D)
use specifies value to solve ![t_0.5](https://tex.z-dn.net/?f=t_0.5)
it is ime required for 50% tranformation
![r = \frac{1}{.0013}=769.2 sec](https://tex.z-dn.net/?f=r%20%3D%20%5Cfrac%7B1%7D%7B.0013%7D%3D769.2%20sec)
Avrami equation is given by
![y = 1 - e^{-kt^n}](https://tex.z-dn.net/?f=y%20%3D%201%20-%20e%5E%7B-kt%5En%7D)
![0.5 = 1 - e^{-kt_0.5^n}](https://tex.z-dn.net/?f=0.5%20%3D%201%20-%20e%5E%7B-kt_0.5%5En%7D)
![1-0.5 = e^{-kt_0.5^n}](https://tex.z-dn.net/?f=1-0.5%20%3D%20e%5E%7B-kt_0.5%5En%7D)
![ln (1 - 0.5) = -kt_0.5^n](https://tex.z-dn.net/?f=ln%20%281%20-%200.5%29%20%3D%20-kt_0.5%5En)
![n = \frac{ ln \frac{ln (1 - 0.5)}{-k}}{ln t_0.5}](https://tex.z-dn.net/?f=n%20%3D%20%5Cfrac%7B%20ln%20%5Cfrac%7Bln%20%281%20-%200.5%29%7D%7B-k%7D%7D%7Bln%20t_0.5%7D)
![n = \frac{ ln \frac{ln (1 - 0.5)}{-2.60*10^{-6}}}{ln 769.2}](https://tex.z-dn.net/?f=n%20%3D%20%5Cfrac%7B%20ln%20%5Cfrac%7Bln%20%281%20-%200.5%29%7D%7B-2.60%2A10%5E%7B-6%7D%7D%7D%7Bln%20769.2%7D)
n = 1.88
second degree of recrystalization may be determine by rearranging original avrami equation
![t = [\frac{-ln(1-y)}{k}]^{1/n}](https://tex.z-dn.net/?f=t%20%3D%20%5B%5Cfrac%7B-ln%281-y%29%7D%7Bk%7D%5D%5E%7B1%2Fn%7D)
for 90%completion
![t = [\frac{-ln(1-0.9)}{2.60*10^{-6}}]^{1/1.88}](https://tex.z-dn.net/?f=t%20%3D%20%5B%5Cfrac%7B-ln%281-0.9%29%7D%7B2.60%2A10%5E%7B-6%7D%7D%5D%5E%7B1%2F1.88%7D)
t = 1456.8 sec
The lane that can be used for both entering and exiting a highway is called; A weave lane
<h3>How to enter a highway?</h3>
When it comes to road highways, there are different terminologies that apply such as Acceleration lane, Deceleration Lane, Interchange, Weave lane, Urban roadway e.t.c
However, when it comes to the one that can be used for both entering and exiting a highway, the correct answer will be Weave Lane because it has both an entrance and an exit for an expressway. Traffic may come onto and leave the expressway at the same location.

Answer:
The note in this question is not an instrument that is negotiable under Article 3 of the U.C.C. Furthermore, it is not payable at any given time on demand due to the fact that principal repayment is not covered at a specified period of time. It shows that the acceleration clause is viable for the payment of the amount upon the default of the maker. This is also for an indefinite period of time.

Answer:
The identified elements and/or features of a product or system are the criteria. (Option # 3).
Answer:
1. Slope = 53.3 x 10⁻⁶
2. Deflection = -0.00016m
Explanation:
given:
let L = 4 m (span of cantilever beam)
let w = 300 N/m (distributed load)
let EI =60 MNm² (flexural stiffness)
dy w * L³ 300 x 4³
1. slope = ------- = --------- = ------------------- = 53.3 x 10⁻⁶
dx 6EI 6 x 60x10⁶
wL⁴ 300 x 4⁴
2. Deflection = y = - ----------- = - ------------------ = -0.00016m
8EI 8 x 60x10⁶
therefore the deflection is 0.16mm downwards.
