Ok, so I added 0.0065 to 0.079318m and got 0.085818m. Then I did 34.9/ 0.085818 and got 406.6737 Hz, but that's not right either.

Ok, so I used this new answer and followed the same steps as I described earlier and its still not the right answer. My answer was 241.927. Its greater than the original frequency, but still not the right answer.

So then I did 34.9 / 220 and got 0.15863 for the wavelength. Then I divided that by 2 and got 0.0793. After that, do I follow the same steps as I desctibed in the problem?

Two strings which are fixed at both ends are identical except that one is 0.65 cm longer than the other. Waves on both of these string propagate with a speed of 34.9 m/sec and the fundamental frequency of the shorter string is 220 Hz. a) What is frequency of the beat that would result if...

I got 2.331644763, which is also not correct.

I attached the picture. Can you see it? Its supposed to be an attachement.

Its still not right. I don't understand any other way to solve for it.

A student gets a 3 kg mass to oscillate up and down on bottom of a light vertical spring by pulling her hand up and down on the top end of the spring. The spring is a real spring with a spring constant of 94 N/m and a damping constant of 0.6 N sec/m. (a) At what approximate frequency should...

Alright, when I converted it, my final answer was 4.386885896 and that is not right.

How do you do that when there's no units for the numerator? I tried doing 4.4 * cos (2pi/29 * 2), but that didnt work. How do you convert it?

I did 4.4 * cos(29*2)= 2.33164. But this is not the right answer.

seconds?

The position of the center of the box shown is given by the equation: x = 4.4 m * cos(29/sec * t) (a) What is the position of the box 2 seconds after the oscillations have started? x = m I don't know how to start A. I plugged in 2 seconds for t in the above equation, but my answer...

So the kinetic energy or the 240,000 J was the Work?

Do you divide 240,000 by 6 seconds? I got 40,000 Watts when I did that which is 40 kW. So is it D?
