Part A)

Distance is given as sum of total path length

So here as we are given that car drives 40 miles East and 30 miles West

So here the total path length is

Distance = 40 miles + 30 miles

distance = 70 miles

Part B)

Displacement is given as straight line distance between initial and final position

So here we can see that

d_1 = 40 miles East

d_2 = 30 miles West

Now the total displacement will be

d = d_1 - d_2 = 40 - 30 = 10 miles

<u><em>so the displacement will be 10 miles East</em></u>

Can density be used to identify what a substance is made of?
Korolek [52]
Possibly, if you have list of densities and you have to match it. I can't think of any other scenarios in which it would be able to.

Hope I helped! :)

A student moves a box across the floor by exerting 56.7 N of force and doing 195 J of
Paha777 [63]

Answer:

A. 3.4 m

Explanation:

Given the following data;

Force = 56.7N

Workdone = 195J

To find the distance

Workdone is given by the formula;

Workdone = force * distance

Making "distance" the subject of formula, we have;

Distance = \frac {workdone}{force}

Substituting into the equation, we have;

Distance = \frac {195}{56.7}

Distance = 3.4 meters.
