This is pretty easy lol.... AS and AR
<h2>
Answer:B</h2>
Explanation:
A solution is a homogeneous mixture of two or more substances. A solution may exist in any phase.A solution has two components.The minor component solute is dissolved in a major component called solvent.
Any option that claims against this definition is wrong.
option A:
Since the solution is homogeneous,it has same properties throughout.
option B:
Solutions contain solute dissolved in solvent not solvent dissolved in solute.
option C:
The solution can be in any phase.
option D:
Solutions are a kind of mixtures because they have no chemical interactions among the solute and solvent particles.
So,option B is wrong.
Answer & Explanation:
In physics, a contact force is a force that acts at the point of contact between two objects, in contrast to body forces. Contact forces are described by Newton's laws of motion, as with all other forces in dynamics. Contact force is the force in which an object comes in contact with another object. Contact forces are also direct forces. Contact forces are ubiquitous and are responsible for most visible interactions between macroscopic collections of matter. Pushing a car up a hill or kicking a ball or pushing a desk across a room are some of the everyday examples where contact forces are at work. In the first case the force is continuously applied by the person on the car, while in the second case the force is delivered in a short impulse.

Hey there!
1.)
The law of conservation of mass states that matter cannot be created or destroyed. This means in a chemical reaction, the products must be equal to the reactants.
2.)
In a balanced chemical equation, there are the same amount of each type of atom, or element, on each side. The products must be equal to the reactants to follow the law of conservation of mass.
3.)
When a chemical reaction occurs, we can see evidence such as bubbles, odor, color change, and heat/light being released. These all are signs that a new substance is being formed.
Hope this helps!
