Answer:
The amplitude of the wave is decreasing with time.
Something is damping the wave (the amplitude is decreasing with time)
The energy possessed by a body because of its motion, equal to one half the mass of the body times the square of its speed is called its kinetic energy.

Hence, when velocity is doubled, kinetic energy becomes 4 times.
Answer:
The answer is "4-5-6 because the bank is growing too quickly in the beginning of its turn".
Explanation:
The S-turns is also known as the reference technique, in which the ground track of the aircraft on both sides of a defined ground-based straight-line distance represents 2 different but equivalent circles.
Throughout the S-turns, on either side of the road, a progressively smaller half-circle is formed, and this turn does not stop until the road or reference line is crossed during the early part of the turn, the twists increase too quickly.
Answer:
708.3 Hz
Explanation:
For an open-air column, like the empty can, the fundamental frequency is given by
where
v = 340 m/s is the speed of sound
L is the length of the column
In this problem, the length of the bottle is
L = 24 cm = 0.24 m
Therefore, the fundamental frequency is
