- Please solve this If \(\alpha,\beta \neq0, f (n) = \alpha^n + \beta^n\)and \(\begin{vmatrix} 3 & 1 + f(1) & 1 + f(2) \\ 1 + f(1) & 1 + f(2) & 1 + f(3) \\ 1 + f(2) & 1 + f(3) & 1 + f(4) \end{vmatrix}\) \(= K (1-\alpha)^2(1-\beta)^2 (\alpha-\beta)^2,\) then K is equal to (a) \(\alpha \beta\) (b) \( {{1} \over \alpha\beta}\) (c) 1 (d) \(-1\)
- In lecture c110504, while solving the question (picture below), you kept R constant which is a constant and you also kept V constant as stated in the question. Ignoring these, you came up with P1=n1T1.Then you said P1=P2. I couldn't understand that properly. We can say P is constant as volume is constant as per Boyle's law, however for that,temperature has to be constant which is not.

- Plz solve the question. A narrow, U-shaped glass tube with open ends is filled with 25.0 cm of oil (of specific graity 0.80) and 25.0 cm of water on opposite sides, with a barrier separating the liquids (Fig. below) (a) Assume that the two liquids do not mix, and find the final heights of the column s of liquid in each side of the tube after the barrier is removed. (b) For the following cases, arrieve at your answer by simpel physical reasoning, not by calculations : (i) What would be the heigh on each side if the oil and water had equal densities? (ii) What would the heights be it the oil's density were much less than that of water?

- A small block of mass m is fixed at upper end of a massless vertical spring of spring constant K = 4mg/L and natural length '10L'. The lower end of spring is free and is at a height L from fixed horizontal floor. The spring is initially unstressed and the spring-block system is released from rest. When free end of spring just touches the ground, the velocity of the block at that instant is 'v'. Then which of the following is (are) true : (a) The magnitude of velocity 'v' is \(\sqrt {2gL}\). (b) Block wil regain the velocity of magnitude 'v', when compression in spring is \(\frac {L}{2}\). (c) Block will reach the velocity of magnitude 'v', twice in a cycle. (d) Block will reach the velocity of magnitude 'v', four times in a cycle.
