A spring whose stiffness is 980 N/m has a relaxed length of 0. 50 m. If the length of the spring changes from 0. 25 m to 0. 81 m
Gelneren [198K]

151.9j

Explanation:

PE=1/2kx^2

PE=1/2(980)(.50)= 245j

PE=(1/2)(980)(.81)= 396.9j

396.9- 245= 151.9j

Define distance and displacement with illustration​
Deffense [45]

Answer:

<h2><em>Distance</em></h2>

<em>The </em><em>length</em><em> </em><em>of </em><em>the </em><em>actual </em><em>path </em><em>travelled by </em><em>a </em><em>body </em><em>is </em><em>called </em><em>distance </em><em>travelled </em><em>by </em><em>a </em><em>body.It </em><em>is </em><em>a </em><em>scalar </em><em>Quantity.</em><em>I</em><em>t</em><em> </em><em>is </em><em>measured</em><em> </em><em>in </em><em>meter(</em><em>m)</em><em> </em><em>in </em><em>SI </em><em>system.</em>

<h2><em>Displacement</em></h2>

<em>The </em><em>shortest </em><em>distance</em><em> </em><em>from </em><em>initial </em><em>position</em><em> </em><em>to </em><em>the </em><em>final </em><em>position</em><em> </em><em>of </em><em>a </em><em>body </em><em>is </em><em>called </em><em>displacement</em><em> </em><em>of </em><em>the </em><em>body.It </em><em>is </em><em>a </em><em>vector</em><em> </em><em>Quantity.</em><em>I</em><em>t</em><em> </em><em> </em><em>is </em><em>measured</em><em> </em><em>in </em><em>meter(</em><em>m)</em><em> </em><em>in </em><em>SI </em><em>system.</em><em>.</em>

<em>Please </em><em>see </em><em>the </em><em>attached </em><em>picture.</em><em>.</em><em>.</em>

<em>It </em><em>is </em><em>the </em><em>example </em><em>of </em><em>distance </em><em>and </em><em>displacement.</em><em>.</em><em>.</em><em>.</em>

<em>Hope </em><em>this </em><em>helps.</em><em>.</em><em>.</em>

<em>Good </em><em>luck</em><em> on</em><em> your</em><em> assignment</em><em>.</em><em>.</em><em>.</em>

Megan walks 1100 m to the left in 330s. What was her average speed in m/s?
Hunter-Best [27]

Answer:

3.33m/s

Explanation:

Speed is the change in distance of a body with respect to time.

Speed = Distance/Time

Given

Distance = 1100m

Time = 330s

Speed = 1100/330

Speed = 3.33m/s

Hence her average speed in m/s is 3.33m/s
