You want to know your grade in Computer Science, so write a program that continuously takes grades between 0 and 100 to standard

Margarita [4]

Answer:

The code is given below in python

# Code Block 1

count = 0 # count variable

total = 0 # total variable

enter = '' # input variable

while enter != 'stop':

enter = input('Enter a grade:' )

if enter != 'stop' and enter.isdigit():

total += int(enter) # add to total value

count = count + 1 # then to the count

print float(total) / count

# Code Block 2

numbers = []

while enter != 'stop':

enter = input('Enter a grade:' )

if enter != 'stop':

numbers.append(int(enter))

print sum(numbers) / float(len(numbers))

For some transformation having kinetics that obey the Avrami equation (Equation 10.17), the parameter n is known to have a value

OleMash [197]

Answer:

t = 25.10 sec

Explanation:

we know that Avrami equation

$Y = 1 - e^{-kt^n}$

here Y is percentage of completion of reaction = 50%

t is duration of reaction = 146 sec

so,

$0.50 = 1 - e^{-k^146^2.1}$

$0.50 = e^{-k306.6}$

taking natural log on both side

ln(0.5) = -k(306.6)

$k = 2.26\times 10^{-3}$

for 86 % completion

$0.86 = 1 - e^{-2.26\times 10^{-3} \times t^{2.1}}$

$e^{-2.26\times 10^{-3} \times t^{2.1}} = 0.14$

$-2.26\times 10^{-3} \times t^{2.1} = ln(0.14)$

$t^{2.1} = 869.96$

t = 25.10 sec
