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!.
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...
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}...
