Answer:
Standing wave
Explanation:
A standing wave is a wave that does not propagate - instead, the oscillations due to the wave occur always in the same place. A standing wave is produced, for instance, when a string (tied on both ends) is made oscillating, or when two identical waves travel in opposite directions.
A standing wave is characterized by two particular types of points:
- There are some points where the amplitude of the oscillation of the wave is always maximum - these points are called anti-nodes of the wave
- There are some points where the amplitude of the oscillation of the wave is always zero - these points are called nodes of the wave.
Hi hi I hope you know that you have a great time jaha
Answer:
a= 4.9m/s²
Explanation:
Using Fnet= mgsintheta = ma
But a= gsintheta
a= 9.8xsin 30
= 4.9m/s²
