GALA ASSIGNMENT 2022 SCIENCE STD 10 SECTION C

Directions: Read the given information carefully and answer the following questions. Three streams Arts, Science, and Commerce are offered in 3 colleges A, B, and C. There are 1750 students in college A. The number of Commerce students in college A is 400 more than that of in Science in college A. the ratio of the number of students in college A in Arts and Science is 23 : 2) (2) There are 3250 students in Arts in all colleges. The number of students in Science in all colleges is 37.5% less than that of in Commerce in all colleges. (3) The number of Arts students in college C is 10% more than that of in college B. the ratio of the number of students in Science in college B to that of in college C is 3 : 4) (4) The number of students in Commerce in college B is 30% less than that in college A. total number of students in college B is 280 less than that of in college C. The total number of students in college B is what percent more/less than that of in Science in all colleges?

(a) Expand STDS (b) Cite any two examples for STDs. (c) Suggest any two methods for the prevention of STDs.

A circuit has section AB as shown in The emf of the cell is 10 V , and the capacitors have capacitances C_(1)=1 muF and C_(2)=2 muF . .

The adjacent figure is the part of a horizontally stretched net. section AB is stretched with a force of 10 N . The tensions in the sections BC and BF are

An iron bar whose cross sectional area is 4cm^(2) is heated from 0^(@)C and 10^(@)C . The force required to prevent the expansion of the rod is [ Y of Iron = 2 xx 10^(12) "dyne" // cm^(2) alpha of Iron = 12 xx 10^(-6 //@) C ]

In a maths paper there are 3 sections A,B& C. Section A is compulsory. Out of sections B & C a student has to attempt any one. Passing in the paper means passing in A & passing in B or C. The probability of the student passing in A, B & C are p,q & 1/2 respectively. If the probability that the student is successful is 1/2 then :
