Please help the right answer get the and this is physical science btw Sadie rides her bike 1600 m East and then turns around and goes 800 m
West. What is her displacement?

(1600 m east) + (800 m west) = (800m east)

Her displacement is 800 m east.

Explanation:

Displacement is the distance and direction between the starting point and ending point,regardless of the route traveled between them.

step-by-step explanation:

we are given

we have to simplify it

firstly, we will factor it

now, we can cancel like terms

now, we can combine it

so, we get

a.) travels faster in solids because the particles are closer together.

air is a gas water is a liquid
