The kinetic energy of an object depends on which of the following?

a.
the object’s mass and direction

b.
the object’s speed and mass

c.
the object’s work and direction

d.
the object’s speed and work

Aneuron is stimulated with an electric pulse. the action potential is detected at a point 3.70 cm down the axon 0.0052 s later. when the action potential is detected 7.20 cm from the point of stimulation, the time required is 0.0063 s. what is the speed of the electric pulse along the axon? (why are two measurements needed instead of only one? )

Which units ate used to measure both velocity and speed? check all that apply
