Answer:
The difference in the phase angle between any two waves at any given position along the waves.
Explanation:
Phase difference describes the difference in the phase angle between any two waves at any given position along the waves. The equation of wave is given by :
Wave 1, 
Wave 2, 
Where
A is the amplitude of wave
is the angular frequency
is the phase difference between two waves
If 
is the path difference, it is given by :
Hence, the correct option is (a) "the difference in the phase angle between any two waves at any given position along the waves".
Answer:
Yes, this is true, unless there were other outside forces, such as wind.
Explanation:
The First Law of Motion states, "A body at rest will remain at rest, and <u>a body in motion will remain in motion unless it is acted upon by an external force."</u>

Hello there!
<span>Which of the following statements is TRUE?
Correct answer: </span>Light waves are electromagnetic waves and sound waves are mechanical waves.
Answer:
Explanation:
Let after time t , Tina catches up David .
Distance travelled by them are equal ,
Distance travelled by Tina
s = ut + 1/2 a t²
= .5 x 2.10 t²
= 1.05 t²
Distance travelled by David
= 30 t ( because of uniform velocity )
1.05 t² = 30t
t = 28.57 s
Distance travelled by Tina
= 1/2 a t²
= .5 x 2.10 x 28.57²
= 857 m approx.
