1. ### Simple Harmonic Wave

For a simple harmonic transverse wave that is propagating along a string toward the right, how is maximum speed of a particle on the string calculated? Is it 4A/T If A=amplitude and T=Period?
2. ### Destructive Interference:

Haha, thanks! Those careless mistakes make such a difference!
3. ### Destructive Interference:

Destructive Interference: Please Help! Two loudspeakers are 2.36m apart. A person stands 2.8m from one speaker and 3.4m from the other. What is the lowest frequency at which destructive interference will occur at this point? My answer is wrong, but this is what I did: 3.4m-2.8m=0.6m, so...
4. ### Understanding the Dynamics of a Simple Pendulum

Because I thought T=mg at 0.
5. ### Understanding the Dynamics of a Simple Pendulum

A simple pendulum consists of a mas M suspended by a thin string. The magnitude of the tension is T. The mass swings back and forth between +,- theta0. I need help identifying which of the following statements are correct. These are my answers, but I'm getting something wrong. A)T=Mg at...
6. ### Unsure how to begin

I'm not even sure how to begin this problem. Can someone help me out? A dog, with a mass of 12.0 kg, is standing on a flatboat so that he is 29.7 m from the shore. He walks 8.7m on the boat toward the shore and then stops. The boat has a mass of 44.0kg. Assuming there is no friction...
7. ### Conservation of Energy Problem

Here's a problem involving conservation of energy. My answer is wrong, but I can't figure out why. I would be extremely grateful for some help :smile: A skier (m=59.00 kg) starts sliding down from the top of a ski jump with negligible friction and takes off horizontally. If h, the...
8. ### True or false questions, Help

Thanks, I figured it out!
9. ### True or false questions, Help

For some reason, my answers to these questions are wrong, but I don't understand which ones and why, please help: A)The speed of an accelerated body changes with time...False B)THe velocity of an accelerated body changes with time...True C)The words motion and acceleration can be used...
