Given a PV cell with light current density of 0.035A/cm2 and reverse saturation current density of 1.5x10-10 A/cm2 . Calculate the voltage and current at the maximum power and also the fill factor under the ambient temperature of 32 o C. Use m=1 for an ideal diode. Plot current and power as a function of voltage from V=0 to V=Voc to verify that the approximation method for maximum current and voltage is a good agreement with the plotted values.

Astone is thrown with a speed v0 and returns to earth, as the drawing shows. ignore friction and air resistance, and consider the initial and final locations of the stone. which one of the following correctly describes the change δpe in the gravitational potential energy and the change δke in the kinetic energy of the stone as it moves from its initial to its final location? options a.δpe = 0 j and δke = 0 j b.δpe is positive and δke is negative c.δpe = 0 j and δke is positive d.δpe is negative and δke is positive e.δpe = 0 j and δke is negative
