List the following aqueous solutions in order of their expected freezing points ( from lowest to highest) : 0.50 m CaCl2 ; 0.15 m NaCl ; 0.10 m HCl ; 0.050 m HC2H3O2 ; 0.10 m C12H22O11. Then explain the reason why you arrange it that way.
Write a program in Python programming language, which allows the user to input an integer value. Based on the input values, the program should perform the following tasks:
⦁ If the entered value is negative then it should print “Factorial does not exist for negative numbers”.
⦁ If the entered value is 0 then it should print “The factorial of 0 is 1”.
⦁ Calculate and display the factorial of the given integer.
Write a program in Python programming language, which allows the user to input a number and upper limit, and based on the input values, the program should perform the following tasks:
⦁ Check whether the value entered by the user is a positive integer.
⦁ Generates an error massage in case of negative integer.
⦁ Generate a table of given number.
⦁ Upper limit for table will be get from user.
2. Survey tests on leadership skills and self-concept were administered to student-leaders.
Both tests use a 10-point Likert Scale, with 10 indicating the highest scores for each test.
Scores for the student-leaders on the tests follow:
Student Code: A B C D E F G H I J
Self-concept : 9.5 9.2 6.3 4.1 5.4 8.3 7.8 6.8 5.6 7.1
Leadership Skill :9.2 8.8 7.3 3.4 6.0 7.8 8.8 7.0 6.5 8.3
a. Compute the correlation coefficient r.
b. Interpret the results in terms of (a) strength and (b) direction of correlation.
c. Find the regression line that will predict the leadership skill if the self-
concept score is known.
d. Predict the leadership skill of a student leader whose self-concept skill is
1.5.
A student conducted a regression analysis between the math grades of his classmates
and the number of times they were absent in the subject. He found that the regression
line y = 97.732 – 2.61x will predict grade (y) if the number of absences (x) is known.
a) What is the predicted grade of a student who has no absences?
b) What is the predicted grade of a student who has ten absences?
c) Sketch the graph of the line predictor.
One box have some apples and another box have some oranges, develop a C++ program to find the sum of fruits and double the sum of fruits in the box using call by address concept
1. Compute the force of attraction between two planets (Planet A and Planet B). The mass of Planet A is 12.34 x 1024 kg and Planet B is 364.25 x 1020 kg and the distance between them is 788,354 km.

1. An inelastic collision occurs in one dimension, in which a 15 kg block traveling at 7.6 m/s collides with a 13.2 kg block traveling at 2.5 m/s in the same direction, and they stick together. What are the velocities of the blocks immediately after the collision?
I. COMPUTATION
1. The momentum of a particle is 50 kg-m/s. If the velocity of the particle is 5 m/s, what is its mass? If the particle is located on a certain planet where the acceleration due to gravity is 5.87 m/s2, what is its weight?
