surface wave of water is due to the disturbance of medium particles
this is also known as mechanical waves
In mechanical waves we need a mechanical medium to disturb the medium particles which will produce the disturbance
While electromagnetic waves do not require any medium and it can propagate through vacuum
Electromagnetic waves are propagation of electric and magnetic field which is due to oscillation of charge.
So electromagnetic field requires to and from motion of charge particle in which time dependent electric field will induce magnetic field and then they induce each other and propagate in the medium
Answer:
6m/s
Explanation:
Given parameters:
Initial velocity = 0m/s
Acceleration = 2m/s²
Distance = 9m
Unknown:
Final velocity = ?
Solution:
To solve this problem, we use the expression below:
v² = u² + 2as
v is the final velocity
u is the initial velocity
a is the acceleration
s is the distance
v² = 0² + (2 x 2 x 9) = 36
v = 6m/s
if they are oriented in the shape of an equaliteral triangle
basically the angle between them is 120 degrees if they both start at the same point
