To solve the problem of determining at which desk students will start laughing and weeping simultaneously due to the diffusion of nitrous oxide (N₂O) and tear gas (C₆H₁₁OBr), we can follow these steps: ### Step 1: Understand the Setup We have 10 equidistant benches (desks) in a classroom. Nitrous oxide (N₂O), a laughing gas, is released from the first desk (Desk 1), and tear gas (C₆H₁₁OBr) is released from the last desk (Desk 10). ### Step 2: Determine Molar Masses - Molar mass of nitrous oxide (N₂O) = 44 g/mol - Molar mass of tear gas (C₆H₁₁OBr) = 179 g/mol ...

A teacher enters a classroom from front door while a student from back door. There are 13 equidistant rows of benches in the classroom. The teacher releases N_(2)O , the laughing gas, from the first bench while the student releases the weeping gas (C_(6)H_(11)OBr) from the last bench. At which row will the students starts laughing and weeping simultaneously?

A cinema hall has equidistant rows 1 m apart. The length of the cinema hall is 287 m and it has 287 rows. From one side of the cinema hall, laughing gas (N_(2)O) is released and from the other side, weeping gas (C_(6)H_(5)COCH_(2)Cl) is released. In which rows, spectors will be laughing and weeping simultaneously?

If a body moves through a liquid or a gas then the fluid applies a force on the body which is called drag force. Direction of the drag force is always opposite to the motion of the body relative to the fluid. At low speeds of the body, drag frog ( F _(P)) is directly proportional to the speed. F_(D) = kv What K is a proportionally constant and it depends upon the dimension of the body moving in air at relatively high speeds, the drag force applied by air an the body is proportional to v^(2) Where this proportionally constant K can be given by K_(2) rho CA Where rho is the density of air C is another constant givig the drag property of air A is area of cross-section of the body Consider a case an object of mass m is released from a height h and it falls under gravity. As it's speed increases the drag force starts increasing on the object. Due to this at some instant, the object attains equilibrium. The speed attained by the body at this instant is called "terminal speed" of the body. Assume that the drag force applied by air on the body follows the relation F_(D) = kv ,neglect the force by buoyancy applied by air on the body then answer the following questions. What is the pattern of acceleration change of the body ?

Two identical beads, each of m=100g , are connected by an inextensible massless string, which can slide along the two arms AC and BC of a rigid smooth wire frame in a vertical plane. If the system is released from rest, the kinetic energy of the first bead when the second bead has moved down by a distance of 0.1m is xxx10^-3J . Find the value of x(g=10ms^-2) (shown situation is after movement of 0.1m ).

Read the following passage and answer the questions that follows: In a class room, four students Sita, Gita, Rita and Anita are sitting at A(3, 4), B(6, 7), C(9, 4), D(6, 1) respectively. Then a new student Anjali joins the class (i) Teacher tells Anjali to sit in the middle of the four students. Find the coordinates of the position where she can sit. (ii) Calculate the distance between Sita and Anita. (iii) Which two students are equidistant from Gita.

(a) A certain mass of gas initially at (1L, 5 atm, 300 K) is expanded reversible and isothermally to final volume of 5L , calculate the work done by the gas and heat supplied in this process to the gas. (b) Now, if the gas is released to initial position by compressing it using an external constant pressure of 5 atm. Find work done on the gas in this process and heat rejected by gas (c ) In the above two processes, what is the net gained by surroundings ? [Note: From above question see that surrounding has done extra work on the system but system has returned that work in the form of heat to surrounding and work is considered on organized form of energy while heat as an unorganised form hence in the above process, there must be net increment in randomness of universe which be called Entropy, soon]
