Which is the best definition of electric charge? A. It is a force of attraction and repulsion by magnetic materials.
B. It is the flow of electrons that have a negative charge to protons that have a positive charge.
C. It is a force of attraction based on an object's mass.

B

Explanation:

Electric charge, which can be positive or negative, occurs in discrete natural units and is neither created nor destroyed. Electric charges are of two general types: positive and negative. Two objects that have an excess of one type of charge exert a force of repulsion on each other when relatively close together. Two objects that have excess opposite charges, one positively charged and the other negatively charged, attract each other when relatively near.

the current is 0.6

voltage ÷ resistance = current

so 12 ÷ 20 = 0.6

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.

not copied too! hope this !
