An object traveling westward with an initial velocity of 11.2 m/s experiences a constant acceleration of 2.78 m/s^2 2 in the eastward direction for 2.03 seconds. During this time, the object travels a distance of:

Find the magnetic field a distance r from the center of a long wire that has radius a and carries a uniform current per unit area j in the positive z direction.

What happens when you slowly pulled the carboard?

Large electric fields in cell membranes cause ions to move through the cell wall. the field strength in a typical membrane is 1.0 x 10 7 n/c. what is the magnitude of the force on a calcium ion with charge +e? what is its acceleration? is it possible for a particle with the same charge as as calcium to have a different acceleration if placed at this location? what would change the acceleration: mass of the particle? diameter of the particle?
