A student walks 10meters east down a hallway before realizing she has dropped a book. She turns around and walks 3meters west to

pick it up. She then turns back around and walks 8 more meters east to her classroom. What is the total distance? What is the total displacement?
If in doubt...sketch it out!


The total distance traveled is 8 m

Her displacement was 10 m east



The total distance traveled is 15 m

Her displacement was 3 m east



The total distance traveled is 10 m

Her displacement was 15 m east



The total distance traveled is 21 m

Her displacement was 15 m east

10 – 3 + 8 = 15 meters

10 + 3 + 8 = 21 meters

Her total traveled is 21 meters, displacement is 15 meters.

A nearsighted person wants to see an apple that is 7 meters away but can only clearly see objects that are at most 62 cm away fr
natulia [17]

Answer:

The power of the corrective lenses is 3.162 D.

Explanation:

Given that,

Object distance = 70 cm

Image distance = 62 cm

Distance between eyes and glasses = 2.5 cm

Eyeglasses made of diverging corrective lenses can help her to see the apple clearly

So now ,

Object distance from glass =70-2.5 = 67.5 cm

Image distance from glass = 62-2.5 = 59.5 cm

We need to calculate the focal length

Using formula for focal length

\dfrac{1}{f}=\dfrac{1}{v}+\dfrac{1}{u}

\dfrac{1}{f}=-\dfrac{1}{59.5}-\dfrac{1}{67.5}

\dfrac{1}{f}=-\dfrac{508}{16065}\ cm

We need to calculate the power of lens

Using formula of power

P=\dfrac{100}{f}

P=-\dfrac{508}{16065}\times100

P=-3.162 \ D

Negative sign shows the lens is diverging.

Hence, The power of the corrective lenses is 3.162 D.

Softa [21]
<h2>Answer:</h2>

<u>Turning a magnet very quickly would be BEST used to create an electric current</u>

<h2>Explanation:</h2>

In Electromagnetic waves electric field produces magnetic field and vice versa. A moving magnet can produce electric current. Dynamo is the best example for it. In dynamo armature is rotated between the magnets which results in the development of electric field and hence an electric current is produced in it.
