The performance of a student in `1^(st)` Term and `2^(nd)` Term is given. Draw a double bar graph choosing appropriate scale and answer the following:

Has the performance gone down in any subject?

Consider this data collected from a survey of a colony. Draw a double bar graph choosing an appropriate scale.

Take the data giving the minimum and the maximum temperature of various cities given. Plot a double bar graph using the and answer the following: Which city has the largest difference in the minimum and maximum temperature on the given data?

In these question, a statement of asertion followed by a statement of reason is given .Choose the correct answer out of the following choices: Assertion and reason both are correct statements and reason is correct explanation for assertion. Assertion and reason both are correct statements but reason is not correct explanation for assertion. Assertion is correct statement but reason is wrong statement. Assertion is wrong statement and reason is also false statement. Assertion:In Young's double slit experiment ,the fringe width for dark fringes is different from that for white fringes. Reason:In Young's double slit experimnet performed witha source of white light ,only black and bright fringes are observed.

In these question, a statement of asertion followed by a statement of reason is given .Choose the correct answer out of the following choices: Assertion and reason both are correct statements and reason is correct explanation for assertion. Assertion and reason both are correct statements but reason is not correct explanation for assertion. Assertion is correct statement but reason is wrong statement. Assertion is wrong statement but reason is correct statement. Assertion:In Young's double slit experiment,the fringe width for dark fringes is equal to that for white fringes . Reason:In Young's double slit experiment performed with a source of white light ,only black and white fringes are observed.

The questions given below consist of an assertion and the reason. Use the following key to choose the appropriate answer. (a) Both the Assertion and the Reason are correct and the Reason is the correct explanation of the Assertion. (b) The Assertion and the Reason are correct but the Reason is not the correct explanation of the Assertion.(c) Assertion is is CORRECT but reason is INCORRECT. (d) If assertion is INCORRECT but reason is CORRECT. (e)If both assertion and reason are INCORRECT. Assertion: In CaF_2, F^- ions occupy all the tetrahedral sites. Reason: The number of Ca^(2+) is double the number of F^- ions.

Two students perform the experiments on series and parallel combinatins of two given resistors R_1 and R_2 and plotted the following V-I graphs: Which of the graph is correctly labelled in term sof the words "series" and "paralle"? justify your answer.
