Answer:
20N
Explanation:
Given parameters:
Work done = 200J
Distance moved = 10m
Unknown:
Amount of force applied =?
Solution:
Work done is the force applied on a body to move it in the direction of the force.
Work done = force x distance
The unit of work done is in joules
Since the unknown is force, we make it the subject of the expression;
Force = 
Force = 
= 20N
<h2>
Answer:Stretched rubber band with an mass</h2>
Explanation:
Simple harmonic motion requires a restoring force.
Simple harmonic motion should be periodic.
Option A:
When a rubber band is stretched,the internal forces of the rubber band pulls the band inside.So,internal forces are the restoring forces in a rubber band.
The motion is periodic as well since the the rubber band makes to an fro motion expanding ans contracting.
So,this performs SHM.
Option B:
There is no restoring force and no periodicity.
So,this is not SHM.
Option C:
There is no restoring force and no periodicity.
So,this is not SHM.
Option D:
There is periodicity but no restoring force.
So,this is not SHM.

The change in energy after the collision is <u>0.5</u>
<u />
<h3>What is change in energy?</h3>
This refers to the difference in the energy where energy is the capacity to do work. There different forms of energy they include mechanical energy, solar energy, electrical energy and so on.
The energy described in the problem is mechanical energy and it is of two types kinetic energy and potential energy
<h3>solving for the change in energy as a result of the collision</h3>
where mass of particle mp = 4 kg
mass of object mb = 6 kg
force constant of spring k = 100 N/m
amplitude A = 2 m
kinetic energy = 1/2 mv^2
initial velocity u = Aω
ω = sqrt ( 100/ 4 )
u = 2 sqrt ( 100/ 4 )
u = 10m/s
final velocity v = 5 m/s
change in energy
= - 0.5 * ( 4 + 4 ) * 5^2 + 0.5 * 4 * 10^2 ) / 0.5 * 4 * 10^2
= 0.5

We Know, F = Gm₁m₂ / r²
When, distance is doubled, it would be:
F' = Gm₁m₂ / (2r)²
F' = Gm₁m₂ / 4r
So, we can see, Force has decreased by 4 times.
Hope this helps!
