An Atwood Machine is set up like the figure below. If m1= 6.0 kg and m2= 4.5 kg, calculate the following:(a.)The acceleration, a, of the system when the masses are releasedfrom rest(b.)The tension force, FT

Light from a sodium lamp passes through a diffraction grating that has 1000 slits per millimeter. the interference pattern is viewed on a screen 1.000 m behind the grating. the first (m = 1) two bright yellow fringes that are visible are 0.7288 m and 0.7300 m from the central maximum. what are the wavelengths of these two fringes?
