Trina makes a diagram to summarize how to use the right-hand rule to determine the direction of the magnetic force on each type of charge.

A venn diagram with 2 intersecting circles. The circle on the left is labeled negative and the circle on the right is labeled positive. There is an X in the negative circle. There is an Y in the intersecting area. There is a Z in the positive circle.

B

Explanation:

Back of the hand faces the direction of magnetic force on a neg. charge (X)

Thumb is the velocity and can be negative or positive (Y)

Palm of the hand faces the direction of magnetic force on a pos. charge (Z)

increases it

note: the given question is incomplete.

complete question is given below.

which is an example of kinetic energy?

a. the energy stored in ethanol  

b. a hockey puck sliding across the ice  

c. a compressed spring  

d. a ball sitting at the top of a ramp

solution: the kinetic energy is the energy posses by the virtue of the motion of the object.

in the given options, a, c and d are the example of potential energy because it is the energy posses by the virtue of the rest of the object. but option b has the kinetic energy as the object is in motion.

hence, a hockey puck sliding across the ice   is the apex example of kinetic energy.

so, the option (b) a hockey puck sliding across the ice   is the correct option.
