It all depends on what kind of wave, and what kind of medium.
For mechanical waves, like sound and earthquakes, the speed
is determined by the mechanical properties of the medium, like
density and stiffness.
For electromagnetic waves, like radio and light, the speed is
determined by the electrical properties of the medium, like
magnetic permeability and electrostatic permittivity.
That's a big part of the reason why sound and light travel
at different speeds through air, water, and jello.
Answer:
Explanation:
Given that,
Mass of ball 1, 
Initial speed of ball 1, 
Mass of ball 2, 
Initial speed of ball 2, 
(at rest)
After the collision,
Final speed of ball 2, 
Let 
is the final speed of ball 1.
Initial momentum of the system is :
Final momentum of the system is :
According the law of conservation of linear momentum :
initial momentum = final momentum
So, the final velocity of ball 1 is (-2.616)m/s.
Answer:
3.33m/s
Explanation:
Speed is the change in distance of a body with respect to time.
Speed = Distance/Time
Given
Distance = 1100m
Time = 330s
Speed = 1100/330
Speed = 3.33m/s
Hence her average speed in m/s is 3.33m/s
Answer:
No it will not (false)
Explanation:
I say this because if anything the ice will sink and melt from a solid to a liquid and that will lead to i guess more water for the aquatic life. (THIS IS A THEORY SHAWTY)
