هلا فيكم عندي مسألتين أتمنى أن يتم حلها من قبلكم مع شرح مبسط إن أمكن طبعا في الفيزياء
(1)
check the correcthness of the relation f=(1/2l)*(T/m) by the method of dimensionswhere f is the frequency , T is the tension in the wire, l is the resonating length and m is the mass per unit length of the wire
للعلم أن (T/m) تكون تحت الجذر
(2)
the velocity a particle at any instant of time is given by v=p + qt +rt^2
where v is in metre/ second and t in seconds. then obtain the dimensionsp,q and r by the method of dimensions
