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.
C. Homogeneous mixtures These alloys are homogeneous mixtures because they have a uniform composition throughout.
Answer:
For the most part radish seed growth is best when they are planted in cool soil; early spring or fall are the preferred seasons for many varieties. Next, be sure to get the soil in good shape before planting – loose, full of seasoned organic material, but not overly fertile. Moisture and soil depth must be right, too.
Explanation:
Answer:
Explanation:
Solubility of many solid in a solvent increases with increase in temperature. Increase in temperature increases kinetic energy of the solute, increasing collision and weakens the intermolecular force within the solute. This makes the solute dissolve faster in their solvents.
During recrystallization, more solutes are added to the solvent at higher temperature so that a supersaturated solution is produced on cooling. As the solution cools the over saturated solute begins to precipitate out of the solution.
Recrystallization is a form of purification if solid, as the crystalline solids continue to precipitate it reject impurities are comes out as a purer solid
