A triple junction Gallium arsenide(GaAs) thin film solar cell can work toharvest solar energy in three bandgaps (250nm-700nm, 700nm-900nm,900nm-1300nm). (1) Please find the fraction of the solar emission energy in each bandversus the total solar emission power.(2) Assume 50% of the emission reaches to the solar panel is harvestedin every band as electrical energy, what is the solar cell energy conversionefficiency.(3) Find the percentage of energy output by each P-N junction/bandgapcompared to that from the total three junctions

Two charged particles, q1 and q2, are located on the x-axis, with q1 at the origin and q2 initially at x1 = 12.2 mm. in this configuration, q1 exerts a repulsive force of 2.62 µn on q2. particle q2 is then moved to x2 = 18.0 mm. what is the force (magnitude and direction) that q2 exerts on q1 at this new location? (give the magnitude in µn.)
