Answer
Bottle B
Reason — Frequency is inversely proportional to the length of the air column ( ). Since pitch is directly proportional to frequency, Bottle B, having a shorter air column due to more water produces a higher frequency and therefore a higher pitch.

The picture below shows a boy climbing a rope ladder hanging from the branch of a tree. The boy in the picture finds it difficult to climb the ladder as it turns about the axis where he is holding. The instructor tells the boy to stretch the body with the hands stretched up and make the body parallel to the ladder and climb
(a) Which force caused the ladder to turn?
(b) How does keeping the body parallel to the ladder make climbing easier?
Regenerative braking involves harnessing the energy that is typically lost when a car decelerates and brakes and instead using it to recharge the car's batteries. Unlike traditional braking systems that simply dissipate energy, regenerative braking allows some of that energy to be recycled.
(a) What is the energy conversion process that results in the wastage of energy in a normal car during braking?
(b) How does regenerative braking differ from normal braking in terms of energy conversion?
