How Does Doubling the Mass Affect Wave Speed on a Wire?

AI Thread Summary
Doubling the mass M hanging from a vertical wire increases the tension in the wire, which affects wave speed. The wave speed is determined by the formula v = √(T/μ), where T is tension and μ is mass per unit length. Increasing the mass results in greater tension, leading to a new wave speed. The correct relationship for wave speed when mass is doubled is v = √2 * V, not just √2. Clarification on terminology, such as "rad 2" versus "root 2," is also discussed.

Homework Statement



When a mass M hangs from a vertical wire of length L, waves travel on this wire with a speed V.

a) What will be the speed of these waves in terms of V if we double M without stretching the wire?

V=?

Good morning, could someone please tell me why my answer of rad 2 is wrong. I thought i was on the right track.

The speed of a wave along a stretched string depends on the tension in the string and the mass per unit length.

v = √(T/μ) where T = tension in the string and μ = mass per unit length.
Can you get it from this??
What do you mean by rad2...
 
Do you mean root2 (√2) ?
 
Thread 'Collision of a bullet on a rod-string system: query'
In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
Thread 'A cylinder connected to a hanged mass'
Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
