⇒ P = 45°

According to question,
A's weight is twice as much as of B.
1. A = 2B.
B's weight is four and half times as much as of C.
2. B = 4.5C
C's weight is half times as much as of D.
3. C = D/2.
D's weight is half as much as of E.
4. D = E/2.
E weight is less than A but more than C.
5. A > E > C
from 1 and 2
6. A = 2B = 9C
from 6 and 3
7. A = 2B = 9C = 4.5D
from 7 and 4
8. A = 2B = 9C = 4.5D = 2.25E
so from 8 and 5
A > B > E > D > C
Descending order of weights of the articles will be
A, B, E, D, C

To group non-contiguous worksheets in Microsoft Excel, you can use the following method:
1. The Ctrl key and mouse:
- Open Excel and go to the worksheet tab bar at the bottom of the Excel window.
- Hold down the Ctrl key on your keyboard.
- Click on the first worksheet tab that you want to include in the group.
- While holding down the Ctrl key, click on the other worksheet tabs that you want to include in the group. You can select multiple non-contiguous worksheets using this method.
- Release the Ctrl key after selecting all the desired worksheets.
- The selected worksheets will now be grouped together.
Note: When you group non-contiguous worksheets, any actions or changes you make to one worksheet will apply to all the grouped worksheets simultaneously.
It is important to note that the other options mentioned in the question are not the correct methods to group non-contiguous worksheets:
- The group button on the standard toolbar (Option A) is used to group contiguous worksheets, not non-contiguous ones.
- The shift key and the mouse (Option B) is used to select a range of contiguous worksheets, not non-contiguous ones.
- The alt enter key (Option D) is used to insert a line break within a cell, and it is not related to grouping worksheets.
Therefore, the correct answer is Option C: The Ctrl key and mouse.

Answer:
The horizontal and vertical scroll bars in a worksheet allow users to navigate and view different rows and columns of data. Here is a detailed explanation of how the scroll bars are used:
1. Split a worksheet into two panes:
- By using the horizontal and vertical scroll bars, you can split a worksheet into two panes. This is particularly useful when you want to view different sections of a large worksheet simultaneously.
2. View different rows and columns:
- The horizontal scroll bar allows you to scroll left and right, enabling you to view different columns of data that are beyond the visible area of the worksheet.
- The vertical scroll bar allows you to scroll up and down, allowing you to view different rows of data that are not immediately visible.
3. Edit the contents of a cell:
- When you click on a cell in a worksheet, the contents of the cell appear in the formula bar. You can use the horizontal scroll bar within the formula bar to edit the contents of the cell if the text exceeds the width of the formula bar.
4. View different worksheets:
- If a workbook contains multiple worksheets, the horizontal scroll bar can be used to navigate between different sheets. You can scroll left or right to switch between worksheets.
In summary, the horizontal and vertical scroll bars in a worksheet are essential tools for navigating and viewing different rows and columns of data, splitting a worksheet into two panes, editing cell contents, and switching between worksheets.

Programmed instruction method is most suitable to teach heterogeneous group of students for self placed learning. Programmed instruction is a method of presenting new subject matters to students in a graded sequence of controlled steps.

Grades and marks come in the category of analytic. When analysis of the performance of the students is done on the basis of grades and marks, it is more reliable and accurate than marks in terms of all possible potential of the students.
Hence, the correct answer is, 'Analytic.'

Diversity in literary terms means differences. The term diversity, when used in discourse related to people or communities or in social contexts is more specific.

• Diversity is that a group of people is made up of individuals who are different from each other in some way or the other or it means collective differences among people, that is, those differences which mark off one group of people from another.
  For example, differences in culture, language, gender, appearance (e.g. skin color, hair type) lifestyle, social and economic status, family structure, abilities, (e.g. physical, social, creative, and intellectual), values, and beliefs.
• In the classroom, it is important that the children interact with each other to minimize the effects of differences with respect to gender, religion, class, caste etc.

 Therefore, it can be concluded that one way of minimizing the effects of diversity is to allow the children to Socialize with each other.

UNESCO is a United Nations' organization that uses education, culture and science as a medium to promote international collaboration and lead to peace and security in the world.

Psychologist Albert Bandura is the researcher most often associated with learning through observation. He and others have demonstrated that we are naturally inclined to engage in observational learning.

Teaching regularly and effectively in a class by teachers develops an interest in students in studies and it prevents them from being absent from school. The teacher must make sure that the study material used in the class is interesting for the students, and that she is able to clearly convey the idea. The involvement of students is also a must to develop interest in studies, and hence reduce absenteeism in the class.

Continuous and Comprehensive Evaluation refers to a school-based evaluation, which covers all aspects of school activities related to a child’s development.

• It emphasizes two-fold objectives such as continuity of evaluation and assessment of learning outcomes in a comprehensive manner.
• It covers all the domains of learning i.e. cognitive, affective, and psychomotor domains.

The concrete operational stage is defined as the stage of child development in which a child starts performing mental operations and starts thinking logically. This stage occurs in children at the age of 7 – 11 years.

The Huygens-Fresnel principle states that every point on a wavefront is a source of wavelets. These wavelets spread out in the forward direction, at the same speed as the source wave. The new wavefront is a line tangent to all of the wavelets.
The correct answer is option B.

We know that for two coherent sources, the intensity of their maxima is (I_max +  I_min)² and that of its minima is (I_max +  I_min)² . Thus we get the intensity of maxima = 121k and that of minima = 9k, for some constant k as (I_max = 100k and  I_min = k.
Thus we get the ratio as 121:81.

Potential gradient Is given by V/l. If V and l are constant, the potential gradient also remains constant. The change in the radius will cause a change in the current. This does not change the potential gradient.

Kirchhoff's Current Law or KCL, states that the “total current or charge entering a junction or node is exactly equal to the charge leaving the node as it has no other place to go except to leave, as no charge is lost within the node“. In other words the algebraic sum of ALL the currents entering and leaving a node must be equal to zero, I_(exiting) + I_(entering) = 0. 

22.4 L of H₂ = 79.5g of CuO
2.80 L of H₂ = 79.5/22.4 x 2.80 = 9.9 g of CuO  

Ionic radius in a group increases from top to bottom since one energy shell is added with each period

Mendeleev's Periodic Table was initially arranged based on increasing atomic mass. He noticed that elements with similar properties appeared at regular intervals when arranged in order of increasing atomic mass.

 Since, 5 and 8 are the remainders of 70 and 125, respectively. Thus, after subtracting these remainders from the numbers, we have the numbers 65 = (70-5),
117 = (125 – 8), which is divisible by the required number.
Now, required number = HCF of 65,117                                     [for the largest number]
For this, 117 = 65 × 1 + 52 [∵ dividend = divisior × quotient + remainder]
⇒ 65 = 52 × 1 + 13
⇒ 52 = 13 × 4 + 0
∴ HCF = 13 
Hence, 13 is the largest number which divides 70 and 125, leaving remainders 5 and 8.

As the case is of 2 consecutive integers, one will be odd and the other one even,
⇒ Their product will always be even i.e. it will always be divisible by an even no., i.e. 2, here.
