A parallel plate capacitor with plates of area (A) and plate separation (d) is charged so that the potential difference between its plates is (V). If the capacitor is now disconnected from the power source and its plate separation is increased to 2d, which statement is correct? a) The voltage between the plates is unchanged.
b) The voltage between the plates is decreased to one-half its original value.
c) The charge on the plates is decreased to one-half its original value.
d) The capacitance is unchanged.
e) The capacitance is increased two times its original value.
f) The charge on the plates is increased two times its original value.
g) The capacitance is decreased to one-half its original value.

  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.

the only real purpose of sputnik 1 was to beat the us into space. we were getting close to launching a useful satellite, explorer 1 - which launched on january 31, 1958. the ussr had to beat that, so they launched sputnik 1 on october 4, 19

false.

explanation:

this statement is false. after falling for 5 seconds, its speed will not be 100 m/s.
