Aparticle starts at the origin and moves away from it in a straight line. after 1.6 seconds it is 12.8 meters from the origin. it then reverses direction due to a force field with a like charge. after 3.8 seconds total , the particle is at -9.23 m what is the average velocity of the particle over 3.8 s?

Which type of microscope would allow the viewer to see ribosomes inside a cell?

Acoil suspended freely, points in some direction when no current is passed through it . can you tell what will happen when a current is passed though it?

The magnitude of the magnetic field at a certain distance from a long, straight conductor is represented by b. what is the magnitude of the magnetic field at twice the distance from the conductor? a. at twice the distance, the magnitude of the field is 4b.b. at twice the distance, the magnitude of the field is 2b.c. at twice the distance, the magnitude of the field is b/2.d. at twice the distance, the magnitude of the field is b/4.e. at twice the distance, the magnitude of the field remains equal to b.
