pulse length = 28.7 cm = 1/2 wave length

Ok, so f'=f(c+v0)/(c-vs)=f(c)/(c-3.18 )=665 Hz f''=f'(c+3.18)/(c)=671.2Hz fbeat = 671.2 - 658.8 = 12.4 Hz Is this correct now?

[FONT=Arial]Yes, I understand now, which means in any situation, if the ropes is at mechanical equilibrium, the tension in the rope is consistent no matter the properties of the rope. Thank you very much.

Homework Statement [FONT=Arial]A cyclist with a bell ringing with a frequency of 658.8 Hz drives towards a wall with a speed of 3.18 ms-1. Just before colliding with the wall the cyclist hears beats, due to the bell itself and the reflection of the sound from the wall. What is the frequency of...

[FONT=Arial]I think if the tension in the thin rope is higher than the tension in the thick rope during the passing process, then the rope will accelerate? but in fact it doesn't? therefore tension in these two mediums is constant? is this correct?

Homework Statement A pulse of length 28.7 cm is transmitted from a thin rope to a thicker rope. If the thin rope has a linear density μ1 = 0.316 g/m and the thick rope has a linear density μ2 = 1.85 g/m what is the length of the pulse in the thicker rope? Homework Equations...

Homework Statement [FONT=Arial]A ball (like the one used in lectures) generating a sound with a frequency of 594 Hz is swung around in a large circle with a radius of 1.49 m. The time it takes the ball to travel around one complete circle is measured and found to be 0.96 s. the speed of sound...

[FONT=Arial]OMG, that was a huge mistake:nb). really really sorry for that mistake I made. But for the second question what would T be? average temperature Tf and Ti? because function T (t) is not given and same problem confused me at the third question. [FONT=Arial]if Tf is half of Ti...

[FONT=Arial]I kind of understand what do you mean now, but I am so confused about the question too, that's why I want some tips for the question, but still really appreciate for your reply. if you think the picture below can help you to figure out your confusion and you do have some ideal how to...

[FONT=Arial]Hi, I am really appreciate for your reply. but I am not sure what do you mean. because I think I used Fourier's law also I am sorry for i didn't make myself clear as ##\frac{dT_f}{dt} = -\frac{P}{m_wc_w+m_mc_m/2}## is given by the question. therefore I think I have to combine these...

[FONT=Arial]Thank you for your reply, and this is my new approach: distance from pivot to centre mass is L/6 torque(mg) = sin(theta)*(L/6)*mg also torque = I*angular acceleration. I am confused here, as w in simple harmonic motion is angular frequency and in the torque formula it is angular...

Homework Statement [FONT=Arial]A warm water bath containing 10.0L of water is connected to an ice-water bath with a piece of metal of length L = 2.11 m and cross sectional area A = 1975 cm2. The metal has a thermal conductivity of km = 60.5 Wm-1K-1, a specific heat of cm = 239.7 Jkg-1K-1 and a...

Homework Statement [FONT=Arial]A L = 1.48 m long metal rod is pivoted from a point one third of the way along its length. The rod has a mass of 0.208 kg. What period will the rod oscillate with when released from a small angle? Homework Equations T = 2 \pi \sqrt{\frac{L}{g}} The Attempt...

[FONT=Arial]Thank you so much, really appreciate you answered all my question with patience !

[FONT=Arial]Sorry, I think I didn't make myself clear enough, of course if the container increase temperature it's open volume will increase, but in the first paragraph, I actually try to say that after container increase temperature, if we put 462.7 mL glycerin in 20 C scale to 105.2 C scale...
