Assume you have the all_info list that is given in the Do It Now problem 1. This list includes the grades of 4 courses for 4 students. Write a code that asks a name from the user. Then it will search for that name in the list all info. Of the name exists in the list, the program will display the programming grade of that student. For example, if the user enters 'Sarah ' the program will display 90. If the user enters a name that is not in the list, such as 'Jack', the program will display an error message such as 'Sorry, but this student is not in the list'.
Answer:
titles =['name', 'physics', 'chemistry', 'math', 'programming']
student_1 =['Kathy', 90, 80, 75, 100]
student_2 =['John', 65, 84, 79, 90]
student_3 =['Joe', 45, 89, 100, 10]
student_4 =['Sarah', 68, 89, 93, 90]
all_info =[titles, student_1, student_2, student_3, student_4]
student = input("Enter student's name: ")
student_list = [name[0] for name in all_info]
if student in student_list:
print(all_info[student_list.index(student)][4])
if student not in student_list:
print("Student name does not exist.")
Explanation:
The python program prompts for user input "student" and the input is used to search and return the result of the student in the programming exam. If the name is not in the student_list, the program print an error message.

What will be the different if the syringes and tube are filled with air instead of water?Explain your answer
Answer:
If the syringes and tubes are filled with air instead of water, the difference would be mainly due to the difference in the properties of air and water. Air is a compressible gas, while water is an incompressible liquid. This would result in a different behavior of the fluid when being pushed through the system.
When the syringe plunger is pushed to force air through the tube, the air molecules will begin to compress, decreasing the distance between them. This will cause an increase in pressure within the tube that can be measured using the pressure gauge. However, this pressure will not remain constant as the air continues to compress, making the measured pressure unreliable.
On the other hand, when the syringe plunger is pushed to force water through the tube, the water molecules will not compress. Therefore, the increase in pressure within the tube will be directly proportional to the force applied to the syringe plunger, resulting in an accurate measurement of pressure.
In summary, if the syringes and tube are filled with air instead of water, the difference would be that the measured pressure would not be reliable due to the compressibility of air.

Define a function ScaleGrade that takes two parameters: • points: an integer, passed by value, for the student's score. • grade: a char, passed by reference, for the student's letter grade. ScaleGrade() changes grade to C if the points are greater than or equal to 67 and less than 80, and grade is not C. Otherwise, grade is not changed. The function returns true if grade has changed, and returns false otherwise. Ex: If the input is 67 D, then the output is: Grade is C after curving. 2 using namespace std; 3 4 int main() { 5 int studentTotal; 6 char studentGrade; 7 bool isChanged; 8 9 cin >> student Total; 10 cin >> studentGrade; 11 12 isChanged = ScaleGrade (studentTotal, studentGrade); 13 14 if (isChanged) { 15 cout << "Grade is " << studentGrade << " after curving." endl; 16 } 17 else { 18 cout << "Grade " << studentGrade << " is not changed." << endl; 19 } 20 1 2 3
Who is least likely to be treated with somatropin?
A 3-year-old cow on a dairy farm
A 4-year-old girl with an XO genetic genotype
A 44-year-old boy with chronic renal failure and gronih deficiency
A 10-year-old boy with polydipsia and polyuria
A 10-year-old boy with polydipsia and polyuria would likely not be treated with somatropin.
This is because somatropin is often used for growth issues and even short bowel syndrome, but from what I could find, nothing about polydipsia or polyuria.
A 3-year-old cow on a dairy farm could need somatropin, specifically Bovine Somatotropin (bST) to increase milk production or fix growth issues
A 4-year-old girl with an XO genetic genotype would get somatropin because it is used to treat Turner syndrome (Same as XO genetic genotype)
A 44-year-old boy with chronic renal failure and growth deficiency would get somatropin because it is used to treat growth issues even in adults and chronic renal failure

The equation of certain traveling waves is y(x.t) = 0.0450 sin(25.12x - 37.68t-0.523) where x and y are in
meters, and t in seconds. Determine the following:
(a) Amplitude. (b) wave number (C) wavelength. (d) angular frequency. (e) frequency: (1) phase angle, (g) the
wave propagation speed, (b) the expression for the medium's particles velocity as the waves pass by them, and (i)
the velocity of a particle that is at x=3.50m from the origin at t=21.os
Answer:
A. 0.0450
B. 4
C. 0.25
D. 37.68
E. 6Hz
F. -0.523
G. 1.5m/s
H. vy = ∂y/∂t = 0.045(-37.68) cos (25.12x - 37.68t - 0.523)
I. -1.67m/s.
Explanation:
Given the equation:
y(x,t) = 0.0450 sin(25.12x - 37.68t-0.523)
Standard wave equation:
y(x, t)=Asin(kx−ωt+ϕ)
a.) Amplitude = 0.0450
b.) Wave number = 1/ λ
λ=2π/k
From the equation k = 25.12
Wavelength(λ ) = 2π/25.12 = 0.25
Wave number (1/0.25) = 4
c.) Wavelength(λ ) = 2π/25.12 = 0.25
d.) Angular frequency(ω)
ωt = 37.68t
ω = 37.68
E.) Frequency (f)
ω = 2πf
f = ω/2π
f = 37.68/6.28
f = 6Hz
f.) Phase angle(ϕ) = -0.523
g.) Wave propagation speed :
ω/k=37.68/25.12=1.5m/s
h.) vy = ∂y/∂t = 0.045(-37.68) cos (25.12x - 37.68t - 0.523)
(i) vy(3.5m, 21s) = 0.045(-37.68) cos (25.12*3.5-37.68*21-0.523) = -1.67m/s.

Write a program that accepts a positive integer N as command-line argument, and outputs True if N is the square of some integer, and False otherwise. Do not use math.sqrt() or similar! Hint: Clearly, all candidates i which may satisfy i2 = N must be at most N (for which "corner case" of N is i equal to N?). Therefore, it is sufficient to check if there exists an i in the range 1 ≤ i ≤ N such that i2 = N. In other words, you want to evaluate the expression (12 == N)or (22 == N)or (32 == N)or ··· or ((N − 1)2 == N) or (N2 == N). Practice goal: A variation of the primality checking program we have seen in class; follows a Boolean accumulation pattern, with logical or.
Answer:
In Python:
N = int(input("Positive integer: "))
if N > 0:
flag = False
for i in range(1,N+1):
if i * i == N:
flag = True
break
print(str(flag))
else:
print("Positive integer only")
Explanation:
N = int(input("Positive integer: "))
If the number is positive
if N > 0:
This initializes a boolean variable to false
flag = False
This iterates from 1 to the input integer
for i in range(1,N+1):
This checks if th number is a square of some integer
if i * i == N:
If yes, flag is set to true
flag = True
The loop is exited
break
This prints either true or false, depending on the result of the loop
print(str(flag))
If otherwise, that the number is not positive
else:
print("Positive integer only")

How does BigQuery's Regexp replace work?For instance, the result of SELECT REGEXP REPLACE("abc", "b(.)", "X1"); is aXc. Only non-overlapping matches are replaced using the REGEXP REPLACE function. As an illustration, substituting ana with banana only causes one replacement, not two. This function gives a false value if the regex parameter is an invalid regular expression. Additionally, it presumes that the input was typed accurately and without any mistakes or typos. You might want to add more validation and error-handling logic to a real-world application to make sure the input is accurate and complete.
# Read street address
street_address = input("Enter street address (4-digit street number, street name): ")
# Split the street address into street number and street name
