kit.

Lab manual activity :

Write Objective, Perquisite knowledge, material required, Procedure, Observation and result

and perform the activities no. 1,3 & 5

Power point presentation:Make presentation on the topic Statistic (ch – 14).

Topic Statistics

Nature of Task Data Presentation

Content coverage

Tabular and graphical representation of data. Presentation of mean, median and mode.

Interpretation of Ogive graph

Guidelines:

There should be minimum 5 and maximum 10 slides

Content should include the entire chapter.

Also bring the hard copy of the same (print out)

Practice questions:

Solve the following questions on A4 size sheet.

If α and β are zeros of the polynomial f(x) = x2-5x+k, such that α-β=1. Find the value of k.

If two zeros of the polynomial f(x) =x3-4x2-3x+12 are √3and -√3 then find its third zero.

Find the zeros of the polynomial f(x) =x3-5x2-2x+24, if its given that the product of its zeros is

12.

Find the value of k for which the given system of equation has a unique solution.

x-ky =2

3x +2y =-5

For what value of k the following system of equation have infinitely many solutions.

2x+3y =4

k+2x+6y =3k +2

The sum of two digit numbers and the number obtained by reversing the order of digits is

121 and the two digits differ by 3, Fin the number.

I am three times as old as my son. Five years later, I shall be two and a half times as old as

my son. How old am I and how old is my son ?

Places A & B are 80 Kms apart from each other on a highway. A car starts from A and other

from B at the same time. If they move in the same direction, they meet in 8 hours and if

they move in opposite direction, they meet in one hour twenty minutes. Find the speeds of

the car.

MANAGEMENT OF NATURAL RESOURCES

Assessment Technique: Project work

Topic of the Project: Learning from the past for sustainable Management of Natural resources

Procedure: The student should prepare the project under the following headings:

Introduction Relevance of today’s scenario

Need for conservation and preservation

Ancient practices (i.e Rain water harvesting, Water conservation, Reduce, Reuse, Recycle, Conservation practices in Bishnoi Community, Water harvesting practices in Rajasthan, Environment friendly technique in Mughal Architecture, Dams in ancient India)

Data collection

Data interpretation

Result and its Interpretation Bibliography

Students shall also collect information / pictures / photographs / or any other illustrations / relevant material from different sources.

STUDENT WORKSHEET

(PHYSICS) I B 1. Graphs between V and I across two conductors A and B A

are plotted as shown in figure . Which of the two conductors

has more resistance?

V

2. Following table gives the resistivity of three samples in(Ωm)

Sample A B C Resistivity in Ωm 1.6 x 10-8 7.5 x 10-7 44 x 10-6

3. Two metallic wires A and B are connected in series. Wire A has length l and radius r, while wire B has length 2l and radius 2r. Find the ratio of the total resistance of series

combination and the resistance of wire A, if both the wires are of same material. 4. Two metallic wires A and B are of same material are connected in parallel. Wire A has

length l and radius r and wire B has length 2l and radius 2r. Compute the ratio of the total

resistance of parallel combination and the resistance of wire A. 5. In the house of Tanmay, there are 20 bulbs each of 100W, three geysers each of 2000W

and 20 tubes each of 40 W. All these appliances work for 5 hrs in a day. Every month, he

pays heavy amount as electricity bill. His son Arihant studying in X standard asked his father to replace all bulbs with CFL bulb each of 40 W to save electricity.

i) How much units of electricity are saved per month (30 days) by replacing bulb with CFL?

ii) What values are shown by Arihant? 6. A welder was asked by Mr. Harshit to weld an iron grill in his house. He started using

electricity by connecting the wires of welding set directly with the transmission wires and

not through the energy meter. Harshit’s neighbour objected the action of welder but Harshit sided with the welder. However, the son of Harshit appreciated the neighbour.

i) Why was the action of welder objected by Harshit’s neighbour ? ii) Why, Harshit supported the action of the welder? iii) Why, Harshit son appreciated the action of the neighbour?
