After carefully studying the infographic, Dineo now needs to choose whether to use a relational database or a NoSQL database. She says that she needs to store the following information:
• She needs to know who built the vehicle, where it was launched from, and when for each launch. For crewed missions, she needs to know who the astronauts were on board.
• Each launch also has multimedia that should be included – a text description, photos, maybe even videos.
Explain to her which type of database (relational or NoSQL) you would recommend, and why, for each of the following types of data.
Q.2.1 Launch data.
Q.2.2 Multimedia related to the launch.
1. When a solution of lead(II) nitrate is mixed with a solution of potassium chromate, a yellow precipitate forms according to the equation.
𝑃𝑏(𝑁𝑂3 )2 (𝑎𝑞) + 𝐾2𝐶𝑟𝑂4 (𝑎𝑞) → 𝑃𝑏𝐶𝑟𝑂4 (𝑠) + 2𝐾𝑁𝑂3
(a)What volume of 0.105 M lead (II) nitrate is required to react with 100 mL of 0.120 M potassium chromate
(b)What mass of 𝑃𝑏𝐶𝑟𝑂4 solid forms?
2. Suppose a titration is run in which 25.05 mL of NaOH solution of unknown concentration reacts with 25.00 mL of 0.1000 M 𝐻2𝑆𝑂4 solution. The chemical equation that summarizes the reaction is as follows:
𝐻2𝑆𝑂4 (𝑎𝑞) + 2𝑁𝑎𝑂𝐻(𝑎𝑞) → 2𝐻2𝑂(𝑙) + 𝑁𝑎2𝑆𝑂4(𝑎𝑞)
What is the molarity of the solution?
3. If a solution of 𝐴𝑔𝑁𝑂3 is added to an HCl solution, insoluble AgCl will precipitate:
𝐴𝑔𝑁𝑂3 (𝑎𝑞) + 𝐻𝐶𝑙(𝑎𝑞) → 𝐴𝑔𝐶𝑙(𝑠) + 𝐻𝑁𝑂3(𝑎𝑞)
(a)What volume of 1.20 M 𝐴𝑔𝑁𝑂3 solution must be added to 250.0 mL of a 0.100 M HCl solution to precipitate all the chloride ion?
(b)What mass of AgCl should precipitate?

a. Form partial differential equation from the relation ½ (𝑧 − 𝑦2) = ƒ (1 + log 𝑦).
b. Solve the partial differential equation of Lagrange’s form (𝑥 − 𝑎)𝑝 + (𝑦 − 𝑏)𝑞 = 𝑧 − 𝑐
a. Solve the differential equation 𝑠i𝑛(𝑥 + 𝑦) + 𝑐𝑜𝑠(𝑥 + 𝑦) − 𝑑𝑦/𝑑𝑥 = 0.
b. Solve the differential equation (𝐷2 + 4𝐷 + 13)𝑦 = cos 3𝑥.
c. Eliminate arbitrary constants from 𝑧 − (𝑥 − 𝑎)2 = (𝑦 − 𝑏)2 to form the partial differential equation
Solve the homogeneous differential equation 𝑥𝑦 𝑑𝑦/𝑑𝑥 = 𝑦2 + 𝑥2 𝑑y/𝑑𝑥 .
Make a file by yourself named ”Integer.txt” and add 5 integer values in it. Now, write a C++
program that reads data (5 integers) from the file and store them in integer array. Also make another
integer array (int result []) of same size to store the results. The program should check for each number
in array if it is prime number or not. If the number is prime, update value in result[] array from 0 to 1.
Lastly, write output in another file named “Result.txt”
Example
Input:
Integer.txt
2 11 1 17 8
Output:
Result.txt
1 1 0 1 0
Hint: Prime number are those which is only divisible by 1 or itself.
Gula Sdn. Bhd was established in 2015. The company owns more than 5
restaurants in Malaysia. In 2016, Gula Sdn. Bhd took out a loan from CICB Bank
for RM 1,000,000.00 in order to expand their business. Unfortunately, after the
pandemic, the business's profit dropped drastically. They failed to pay monthly
installments. The company also unable to pay the employee's salary. CICB Bank
had sent a few notices to demand the arrears of payment.
As a lawyer, advise CICB Bank whether they can apply for winding up by court
and whether they have grounds to do so?

Lily has been appointed as an auditor in Yujung Construction Sdn. Bhd. One day,
her colleague Mr. Kim had informed her that the company accounts are not
properly drawn up. The upper management had embezzled the fund for illicit and
bribery. Lily felt very shocked and he told Lily to keep it a secret as he is still
being investigated about that. The next day, it shows that Mr. Kim had been
removed from his post in the company. Lily felt very dissatisfied with that and
started to investigate on her own.
During the general meeting, Lily as an auditor made a statement that the company
had embezzled the money for illicit purposes and fighting for Mr. Kim's right. The
upper management wants to sue Lily for defamation of the company due to the
statement that she made during the general meeting.
Discuss, whether Lily can be liable for her action for defamation in respect of her
statement as an auditor?
