A kite is a quadrilateral (has four sides and four angles) with two pairs of congruent adjacent sides.
From the image we can see that one pair of congruent side has be formed with a length of 30 feet. Therefore the amount of rope that has been used is 60 feet and 40 feet (100 - 60) of rope would be remaining to complete the kite. Hence 40 feet of rope would be used to make the other pair of adjacent side.
This means that the remaining pair of adjacent side would be 20 feet each so that all the roe would be used.
Changes in the pressure create the flow of the air to move up and down in the ear and thus create popping sound.
Explanation:
The ear-popping is caused by the phenomenon of the opening of the Eustachian tube when one swallows and it might be automatically when you blow our nose or are setting in an airplane and this sound is created when the air enters the middle ear through the tube.
