Convert the following db to decimal a. -12 b. 3 c. 10 d. 0

for -12db

for 3db

for 10db

for 0db

Explanation:

The decibel is a logaritmic value given by:

we use 10 for power values and 20 for other values such voltages or currents.

for -12db

for 3db

for 10db

for 0db

  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.
