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.
Answer:
The minimum force is required is, f = 0.3 mg Newton
Explanation:
Given data,
The coefficient of the static friction, μₓ = 0.3
Let the mass of the wheel is, m = M kg
The minimum force required to set the wheel in motion is equal to the force of static friction. This amount of force can be applied tangentially to the wheel in a vertical direction to set the wheel in motion.
<em> Fₓ = μₓ. F</em>
Where F is the normal force acting on the wheel and it is equal to mg.
Therefore, the minimum force is required is, f = 0.3 mg Newton
This answer is false. A visual artist is defined as someone involved in the arts of painting, sculpting, photography, etc, as opposed to music, drama, and literature. A visual artist is in the form of making somthing more visable. So, a graphic designer is a visual artist.
