A shopper walks westward 5.4 meters and then eastward 7.8 meters

We put a force of 50n on an object and the acceleration is 100 m/s². what is the mass of the object?

What organization and environment is described above?

Point charges q1=+2.00μc and q2=−2.00μc are placed at adjacent corners of a square for which the length of each side is 1.50 cm . point a is at the center of the square, and point b is at the empty corner closest to q2. take the electric potential to be zero at a distance far from both charges. part a what is the electric potential at point a due to q1 and q2? express your answer with the appropriate units.
