When 2 waves interefere (or collide with eachother), it usually affects the crest of the wave. If both waves collide with both crests, it will create an amplified crest, and the waves will pass through eachother afterwards. If a trough of a wave meets a crest, it will cause the crest to be lowered shortly before both continue on.
4000 seconds
Explanation:
speed = distance / time
0.0004m/s = 1.6m / time
Subject time
time = 1.6 / 0.0004
time = 4000 seconds.
Hope this helps. Mark as brainliest if possible. tks
Answer: the force of impact is the same in magnitude for both the winshield and the bug, and in opposed directions.
Explanation:
1) Whenever two objects are in contact you have to think about the Third Law of Newton, named action-reaction force.
2) According to this law, action and reaction have the same magnitude but opposite directions.
3) Think that forces always come in pairs. They act over different objects, have the same magnitude and act on opposite directions. Some additional examples are:
i) When you kick a stone, the force of your foot on the stone is the same force of the stone on your foot.
ii) When you stand on the ground, the force that your feet exert on the ground is equal to that that the ground exerts on you feet, but in opposite direction.
iii) When you push a block, the block pushes you with the same magnitude.
Given :
Initial velocity, u = -6 m/s.
Time taken, t = 4 seconds.
Acceleration due to gravity, 
.( Here negative sign means downward direction )
To Find :
Velocity after 4 seconds.
Solution :
By equation of motion.
v = u + at
Here , a = g.
v = u + gt
v = -6 + (-9.8)×4
v = -6 + (-39.2)
v = -45.2 m/s
Therefore, velocity after 4 seconds is -45.2 m/s.
Hence, this is the required solution.
