Hannah made a chart to describe speed and velocity.

which best describes how to correct hannah's error?

speed

scalar quantity

calculated by dividing

time by distance

has magnitude

depends on a reference

frame

velocity

vector quantity

calculated by dividing

change in position by time

is a displacement

depends on a reference

frame

switch the chart headings "speed" and "velocity."

describe the calculation for speed as "dividing distance

by time."

in the "speed" column, change "has magnitude" to "is a

displacement."

change the last row of the "velocity" column to "does

not depend on a reference frame."

Describe the calculation for speed as "dividing distance  by time."

Explanation:

As we know that distance is the ratio of distance and time

so we can say that the speed of the given object is

while velocity is a vector term

so it is defined as the ratio of displacement and time

so speed must have magnitude while velocity must have direction and magnitude both

so correct answer will be

Describe the calculation for speed as "dividing distance  by time."

i think its

they are non-matter

explanation:

they are non-matter. basically, any type of energy or any abstract concept is an example of something that does not matter. other examples include dreams, magnetism, radio, and hate
