A group of students are measuring how the acceleration of a mass will change due to a force.
Fudgin [204]

The graph of the plot of acceleration against force is a straight line graph. Option B

<h3>What is the relationship between force and acceleration?</h3>

From the Newton's second law of motion we can derive that; F = ma

F= mass

a = acceleration.

This implies that the acceleration and the mass of a body has a linear relationship. We could then assert that the force is directly proportional to the acceleration with the mass being the constant in the equation.

As such, the force that is imparted to the body is what determines the acceleration and the both increases or decreases linearly. Thus the graph of the plot of acceleration against force is a straight line graph. Option B

How does the comic strip define a polar molecule
zmey [24]

The answer is: A molecule with a difference in electrical charge between two ends.

Electronegativity (χ) is a property that describes the tendency of an atom to attract a shared pair of electrons.

Atoms with higher electronegativity attracts more electrons towards it, electrons are closer to that atom.

For example fluorine has electronegativity approximately χ = 4 and oxygen χ = 3,5, fluorine attracts electron and he has negative charge and oxygen has positive charge.

If metal ions in a solution were reduced, what would you expect to see?
marysya [2.9K]

Answer:

Solid metal

Explanation:

The reduced form of metal ions is the metal in elemental state (simple substance). So, if you have a solution with metal ions and they are reduced, you probably will see the deposition of the metal. For example: if you have a solution with sodium ions (Na⁺), and the ions are then reduced, you will see the aparition of a solid phase of metallic sodium (Na(s)), according to the following half-reaction:

Na⁺ + e- → Na(s)
