If a and b are hermitian operators, prove that (1) the operator of ab is only hermitian if a and b commute, and (2) the operator (a+b)" is hermitian

i think if it were me i whould divide 300 dide 15

step-by-step explanation:

battery with hi vtge high val resist in series

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.

because if the tool that you are using is not balanced it there would be false mass.
