The equipment is an osciloscope, a function generator and an emisor of sound waves and a receptor, it will be for a college level. It will be a great help if the experiment is explained in a book. Thanks!.

Hi everyone! I have to do an experiment in the lab related with interference in sound waves with same frecuency. I am just looking for ideas or suggestions. Thanks!.

I'm sorry for the inconviniences. I will edit my post.

Im not sure about this, maybe the problem is too easy or i have no idea about what I am doing, but you have one incognit and one ecuation defined in the following way: m_p sin i = K M^{2/3} ( \frac{P}{4.19 \times 10^{-10} \frac{Nm^2}{Kg^2} } )^{1/3} (1) Also you have:K = 62.5 m/s P = 379440...

I had a hard time trying to understand what do you want to find, also can you be more specific about the data that you have? Define k and P please.

The center of mass expression is defined by the following: \overline{R} = \frac{\sum_i^n \overline{x}_i m_i}{ \sum_i^n m_i } Where x_i are the positions of the particles, an m_i are the mases of these particles. In your example you have to do the following: |\overline{R}_{sj}| =...

You have to integrate the aceleration two times to get the movement ecuation. You know that: x (t) = x_0 + v_0 (t-t_0) + \frac{1}{2} a (t-t_0)^2 v (t) = v_0+ a (t-t_0) Part one we start from time, position and initial velocity cero and also positive aceleration f: x (t)...

We know that torque is calculated in the following way. \sum_i^n \overline{T_i} = \sum_i^n \overline{r} \times \overline{F} _i (1) Also we know that there are two external forces that are applied in the ball: The tension of the string: \overline{T} = -T \widehat{x}...

Wow!.
