Since static friction is the minimum force required to just start the motion of a stationary object.
Here if we need to start an object from rest then we required F = 700 N
So for the first part of the above problem Force will be F = 700 N
Now if the box is already moving then we will have to use kinetic friction force between box and floor
now we can write the equation of net force as
here
now we will have
The adaptation of a cheetah is shown in the image which shows it running is its long and strong legs to run fast which is denoted as option B.
<h3>What is Adaptation?</h3>
These are the physical and behavioral features which ensures that they survive in their changing environment.
Cheetahs are known to have long and strong legs which is the reason why it runs at a very high speed.

First you will want to sketch out both of the situations. It should be two sketches, one for the flagpole and one for the building.
To solve this, you will want to create a proportion.
Flagpole height/flagpole shadow=building height/building shadow
Therefore, it should look like this:
50/30= 300/x
Solve for x:
50x=9,000
X= 180 feet
YOUR ANSWER IS C.
They bounce off just like sun rays when they heat the atmosphere they bounce off reflection
