Answer:

<h2>A. Energy is absorbed in the reaction.</h2>

Explanation:

In chemistry, there are two types of reactions: <em>Exothermic and Endothermic Reactions.</em>

An <em>exothermic reaction </em>occurs when the reactants have higher energy than the products, the effect is <em>energy released</em>.

On the contrary, an <em>endothermic reaction</em> is when the products have higher energy than reactants, and the <em>energy is absorbed.</em>

So, based on these concepts, the correct answer is A, in a given chemical reaction, if the energy of the products is greater than the energy of the reactants, energy is absorbed.

An object in motion will have a speed which is a scaler , or ( blank ) which is a vector .
mylen [45]

Answer:

Velocity

Explanation:

Objects in motion usually have a speed which is scalar or velocity which is a vector.

A scalar quantity is one with magnitude but has no directional attribute.

A vector quantity is one with both magnitude and directional attribute.

Speed is a scalar quantity that describes the magnitude of motion a body accrues.

Velocity is a vector quantity that describes both the magnitude of motion and the direction of motion in a body.

How does the amplitude of the wave change as you get farther from the speaker?
KatRina [158]

Answer:

The amplitude decreases

Explanation:

From the inverse square law, we know that;

I ∝ 1/d²

Where;

I is intensity

d is distance

Also, we know that;

A² ∝ I

Where A is amplitude

Thus, we can say that;

A ∝ 1/d²

Thus, amplitude is inversely proportional to the distance.

So the larger the distance, the lesser the amplitude and the lesser the distance, the higher the amplitude.

Thus, as you move farther from the speaker the distance increases and therefore the amplitude decreases
