This  organ is capable of storing blood that can be released into circulation when the animal needs it.

What type of immunologic cell can protect an animal from a pathogen after the animal’s initial exposure and during a subsequent exposure?

Two point charges are on the x-axis.  Charge q1 = -7.0 uC is at the origin and q2 = 10 uC is at x = 0.40 m.  Find the electric potential at x = 0.80 m.

A 3.67 uC point charge gains 1.6 J of potential energy when it moves between two points in an electric field.  What is the potential difference between these two points?

What magnitude of electric force will a 2.1 uC charge experience if it is placed in an electric field of magnitude 3.6 x 10^4 N/C?

A 4.5 u C point charge is released from rest in a uniform electric field of magnitude 1.47 x 10^4 N/C.  The mass of the charge is 2.8 x 10^-4 kg and the electric force is the only force present.  Find the speed of the charge when it has moved a distance of 0.65 m in this field.

Three point charges are on the x-axis.  Charge q1 = 7.6 uC is at the origin, q2 = -4.2 uC is at x = 0.40 m, and q3 = -3.1 uC is at x = 0.75 m.  Find the magnitude of the electric force acting on charge q3.
