A uniform thin rod of mass =3.41 kgM=3.41 kg pivots about an axis through its center and perpendicular to its length. Two small bodies, each of mass m=0.249 kgm=0.249 kg , are attached to the ends of the rod. What must the length LL of the rod be so that the moment of inertia of the three-body system with respect to the described axis is =0.929 kg·m2I=0.929 kg·m2

Starting with only the balmer series light (visible light), how could we ensure that the solar panels generate a current that mark can use for his power station? a)by gradually increasing the brightness (amount) of light that we shine on it. b)by gradually increasing the frequency of the light we shine on it. c)by gradually increasing the wavelength of the light that we shine on it.
