A closed organ pipe of length L and an open organ pipe contain gases of densities ρ\(_1\)and ρ\(_2\) respectively. The compressibility of gases is equal in both the pipes. Both the pipes are vibrating in their first overtone with the same frequency. Please help me to find the length of the open organ pipe.Topic: AMIE
A hydrogen electrode X was placed in a buffer solution of sodium acetate and acetic acid in the ratio a:b and another hydrogen electrode Y was placed in a buffer solution of sodium acetate and acetic acid in the ratio b:a. If reduction potential values for two cells are found to be E\(_1\) and E\(_2\)respectively w.r.t. standard hydrogen electrode, what would be the pKa values of the acid? Please explain the answer in brief.Topic: Chemistry
An open pipe of sufficient length is dipping in water with a speed v vertically. If at any instant l is the length of tube water. Then the rate at which fundamental frequency of pipe changes, is. (speed of sound = c)Topic: AMIE

A string fixed at both ends is vibrating in the lowest mode of vibration for which a point at a quarter of its length from one end is a point of maximum displacement. The frequency of vibration in this mode is 100Hz. What will be the frequency emitted when it vibrates in the next mode such that this point is again a point of maximum displacement? Please explain the answer in brief.Topic: AMIE
A point P lies on the axis of a ring of mass M and radius a, at a distance a from its centre C. A small particle starts from P and reaches C under gravitational attraction only. What would be its speed at C? Please help me to solve this problem.Topic: Physics

A simple pendulum has a string of length l and bob of mass m. When the bob is at its lowest position, it is given the minimum horizontal speed necessary for it to move in a circular path about the point of suspension. The tension in the string at the lowest position of the bob is.Topic: AMIE
A ball is projected upwards from the foot of a tower. The ball crosses the top of the tower twice after an interval of 6s and the ball reaches the ground after 12s. What would be the height of the tower? (g = 10m/s\(^2\) )Topic: AMIE
Compound A has molecular formula C\(_2\) Cl\(_3\) OH. It reduces Fehling’s solution and on oxidation it gives monocarboxylic acid, B. If A is obtained by the action of chlorine on ethyl alcohol, the compound A is.Topic: Chemistry
My sir Mr. Gadadhar Nayak is a very excellent teacher. He is a sincere person and his teaching method is very good.
She is an experienced teacher in Mathematics and has very good skills in overall subjects. She teaches me Mathematics in very effective way. I get very good marks in my subject. She is best for me and I recommend her to others.
Quality Of Teaching is amazing. He explains very well.
Took Math and Computer tuition from Sir for my B. Tech level, teaches quite well and explains the concepts in easy-to-understand details.
She is a good blend of fun and educare. I have always felt free to approach her with my doubts and she is always available. She is a good planner and has helped many students like me to plan out the study schedule. She is highly enterprising and I have had a good learning experience as her student. Thank you.
Manoj sir is an excellent teacher, a humble disciplined sir I ever met. He teaches very well.
My sir is excellent in Mathematics. He can explain any difficult Math in an easy process and very quickly. I am grateful to him.
I have taken classes of HTML and CSS. He is best in HTML/CSS. With the guidance of Sir, I have now designed many web pages. He is the best option for HTML.
He is very cooperative and very talented tutor in Bhubaneswar. He has the best knowledge about web development technology. I am very satisfied with his coaching and will highly recommend him to other students who need the best web development tuition.
His teaching method is really very good. It helps us understand the subject very easily.
