Answer:
Wave Variables
In the chapter on motion in two dimensions, we defined the following variables to describe harmonic motion:
Amplitude—maximum displacement from the equilibrium position of an object oscillating around such equilibrium position
Frequency—number of events per unit of time
Period—time it takes to complete one oscillation
For waves, these variables have the same basic meaning. However, it is helpful to word the definitions in a more specific way that applies directly to waves:

Explanation:
Answer:
the lowest point, where the amount of energy is the greatest
Explanation:
The correct answer is "The roller coaster cars determine the amount of kinetic energy in the system. It’s the only part of the system that moves. Kinetic energy depends on the velocity and mass of a moving object."
Answer:
Matter is everything that surrounds us. It has mass and occupies a place in space. Matter can be described by measuring the value of its properties; for example: density, color, mass, volume, etc.
al ser homogenea no se puede percibir con la vista pero si se le agrega acido sulfurico la reaccion hara que el hidrogeno y el oxigeno se evaporen dejando unicamente una masa negra de carbono
No, ya que, es una mezcla homogénea, es decir, sus elementos están muy unidos mas no combinados de manera química, es posible separarlos pero con mucha dificultad, por tanto, es imposible diferenciarlos a simple vista. Se sabe que están distribuidos de manera uniforme, su estado es conocido como solución o disolución, tal como es el caso del azúcar.

Answer: Positive
Explanation:
Are you familiar with differential calculus? In a plot of position vs. time, the velocity at any given moment is the derivative at that point. A derivative is just the slope. For this plot, the slope is x/t.
Looking at t = 1s, the slope is 1/1. This means the velocity is a positive 1m/s at time equal to 1 second
Answer:
D. Steel is made of different compounds distributed unevenly.
Explanation:
The statement that will support her claim that steel is a homogenous mixture is that steel is made up of different compounds distributed unevenly.
- Steel is an alloy of carbon and iron in its composition.
- Alloys are classified as mixtures.
- Their constituent reacts differently to changed medium.
- The iron in steel does not chemically bond with the carbon.
