Answer:
a = 0
Explanation:
The velocity of a sound wave in a straight line is 660 mph. The wave is moving with a constant velocity. It means that the change in velocity is equal to 0.
We know that acceleration of an object is equal to the change in velocity divided by time taken. But here the change in velocity is 0. As a result the acceleration of the sound wave is 0.
Newton's third law<span> is: For every </span>action, there is an equal and opposite reaction. This means that in every interaction, there is a<span> pair of forces acting on the two interacting objects.</span>

Answer: the acceleration is (g( 1 - sinθ)) / 2
Explanation:
the tension in one bag is expressed as;
T = ma + mg sin θ ........................lets say equ 1
now the tension in another bag is expressed as;
T = -ma + mg..................lets say equ 2
so equate both equations
ma + mg sinθ = -ma + mg
2ma = mg ( 1 - sinθ)
a = (g( 1 - sinθ)) / 2
therefore the acceleration is (g( 1 - sinθ)) / 2
