The image shows two opposite forces acting on a rolling cart, what can we say is true about the effect on the forces on the cart
1 answer:
Question options:
1. It cannot be determined without knowing which man is stronger.
2. The forces are unbalanced, and net force on the cart moves it to the left.
3. It cannot be determined because one man is taller than the other.
4. The forces are unbalanced, and net force on the cart moves it to the right.
Answer:
<em>2.The forces are unbalanced, and net force on the cart moves it to the left.</em>
Explanation:
In the image, two opposite forces acting on a rolling cart. The person on the right side exerting more force (50N) toward the left than the person on the left side (10N). The more the force applying on the object, it will drag on the followed direction.
It is because the person on the right side exerting force (50N) toward the left, rolling cart will moves to the left.

<u>Answer:</u> In a chemical reaction, the total mass of the particles in the system stays the same
<u>Explanation:</u>
Law of conservation of mass states that mass can neither be created nor be destroyed but it can only be transformed from one form to another form.
This also means that total mass on the reactant side must be equal to the total mass on the product side in a chemical reaction.
Every balanced chemical reaction follows law of conservation of mass.
<u>For Example:</u> Formation of water molecule
Total mass on reactant side =
Total mass on product side =
Hence, in a chemical reaction, the total mass of the particles in the system stays the same
