Suppose that two pith balls, each with a charge of 1 coulomb, are hanging in the lab room, seperated by a distance of 1 meter, and applying a force on eachother. what will be the magnitude of the electrostatic force between them?

Alead ball is dropped into a lake from a diving board 5m above the water . it hits the water with a certain velocity and then sink with constant velocity in bottom . it reaches the bottom 5 second after it is dropped if g= 10m/s2 . find depth of the lake and average velocity of the ball ?

What is special about a dc circuit ?

This is one type of line graph in which the independent variable is time plotted on the x axis and the dependent variable, also numerical, is plotted on the y axis.
