Answer:circulatory system
Answer:
Therefore,
The speed of the wave on the longer wire is 95 m/s.
Explanation:
Given:
For Short wire, speed is
Let length of Short and Longer wire be 
such that
To Find:
Speed on the longer wire
Solution:
The speed of a pulse or wave on a string under tension can be found with the equation,
Where,
= Tension on the wire
L = Length of Sting
m = mass of String
So here we have,
= same
Therefore,
......equation ( 1 )
And
.......equation ( 2 )
Dividing equation 1 by equation 2 and on Solving we get
Therefore,
Therefore,
The speed of the wave on the longer wire is 95 m/s.
A cation
Cations are positive ions that have lost an electron
Diffusion is different from osmosis. Diffusion is when a solute passes through a semipermeable membrane inorder to reach equalibrium, while osmosis is water passing through a semipermeable membrane in order to reach equilibrium. Diffusion is when a higher concentration dilutes a lower concentration to reach its most equal state.
Answer:
Vf = 5.05 m/s
Explanation:
To know this, you need to use the expressions for free fall.
In this case, we only know the length of the stick which is 1.3 m.
The stick is held vertically and then is allowed to fall freely. Now, we want to know the final speed of the stick when it reach the floor.
In this case, we can assume that when the stick is allowed to fall, the innitial speed is 0. Then, the other thing we can assume is the height where the stick is put to fall. In this case, the height is the same as the length, because the stick is already on the floor but is standing vertically.
So, we have here the height, and if the stick is falling, is because of gravity, which is 9.8 m/s²
To calculate the speed, you can use this expression:
Vf = √2*g*h
Replacing the data we have:
Vf = √2 * 9.8 * 1.3
Vf = 5.05 m/s
