Seek to determine the characteristics of a solar panel for a luminous flux of 10 00 w. m2 . dimensions of the solar panel: 1500 x 800 x 50 (in mm). the figure below presents the electrical characteristics of the panel. we give : received luminous power = s maximum electrical power = urface x v mpp x i luminous flux mpp e fficiency ( η ) = ( maximum electrical power ) / (r eceived l uminous power ) 1. specify the types of energies absorbed and useful for a photovoltaic panel. 2. determine from the figure: a) b) the maximum power deliver the ed by the photovoltaic panel p voltage at the point of maximum power v c) mpp . m . the intensity of the current at the point of maximum power i 3 . calculate the efficiency of the photovoltaic panel η. mpp .

i don’t know what the answer is i wish i

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.

force is based upon mass and acceleration.the statement is not always true.

it can be explained from newton's second law of motion.

as per newton's second law of motion the rate of change of momentum is directly proportional to the applied force and takes place along the direction of force.

mathematically it can be written as -

                                              ⇒      

here   k is the proportionality constant whose value is 1.

                                                            [a is the acceleration=dv/dt]

hence we see that force not only depends on mass and acceleration but also on velocity and rate of change of mass. force f will depend on mass and acceleration only when mass is constant.

hence the statement that force is based upon mass and acceleration is false.
