Vectors vs. Scalars Most of the quantities used to describe motion can be categorized as either vectors or scalars. A vector is a quantity that is fully described by both magnitude and direction. A scalar is a quantity that is fully described by magnitude alone. Categorize the following quantities by placing them under one of the two column headings.

displacement, distance, speed, velocity, acceleration

Will you chech and finish these for me, because i am stumped with them.

A3.9 g aluminum foil ball with a charge of +4.1×10−9 c is suspended on a string in a uniform horizontal e⃗ field. the string deviates to the right and makes an angle of 30∘ with the vertical. part a part complete what information about the e⃗ field can you determine for this situation? what information about the field can you determine for this situation? only the magnitude of e⃗ only the direction of e⃗ both the magnitude and the direction of e⃗ none of the above previous answers correct part b determine the magnitude of the electric field. express your answer with the appropriate units. e e = nothing nothing request answer part c determine the direction of the electric field. determine the direction of the electric field. to the right to the left away from you toward you
