Answers
Answer:
An idea, event, or object can be represented by a 'model' to help people better understand it.
Explanation:
If an idea, event or object is to be represented or introduced to an individual or a group of people, a good idea is to represent it with a model.
The reason behind it being that a model will help the people understand it better as they will be able to see something in front of it and know what is being discussed.

Answers
To apply the same force as the person, the brother have to sit at a distance of 5 m.
What is meant by torque ?
Torque is defined as the rotational analogue of force. It is the cross product of force and the displacement of the object.
Here,
Mass of the person, m₁ = 50 kg
Mass of the brother, m₂ = 20 kg
Distance of the person, d₁ = 2 m
For the see-saw to get balanced, the torque applied by the two persons each side must be equal.
τ₁ = τ₂
where τ₁ is the torque applied by the person and τ₂ is that applied by the brother.
So, F₁d₁ = F₂d₂
m₁g x d₁ = m₂g x d₂
m₁d₁ = m₂d₂
Therefore, distance of the brother,
d₂ = m₁d₁/m₂
d₂ = 50 x 2/20
d₂ = 5 m
Hence,
To apply the same force as the person, the brother have to sit at a distance of 5 m.

fulcrum to get the correct mechanical advantage?
Answers
Answer:
The distance of load from fulcrum is 5 m.
Explanation:
Given:
Mechanical advantage, MA = 0.4
Distance of force from fulcrum is,
Distance of load from fulcrum is,
We know that, Mechanical advantage of a machine is the ratio of the effort arm and load arm.
So, Mechanical advantage is given as:
Therefore, the distance of load from fulcrum is 5 m.
