4. True
5. The amplitude of the ripples decreases as the circumference of the circle increases.
<h3>What is a wave?</h3>
A wave is a disturbance that moves energy from one place to another.
Radio waves, gamma-rays, visible light, and all the other parts of the electromagnetic spectrum are electromagnetic radiation. Electromagnetic radiation can be described in terms of a stream of mass-less particles, called photons, each travelling in a wave-like pattern at the speed of light. Hence, the statement is true.
As the disturbance moves outwards the energy it carries is spread over a larger and larger region called the wavefront. For example, the ripples in the water lie in a circle with an ever-increasing circumference. The amplitude of the ripples decreases as the circumference of the circle increases.

Answer:
It pushes back with equal force.
Explanation:
This is pretty much newton's first law.
To balance this equation simply place the coefficient 2 in front of both the iron metal and the iron II oxide FeO.
The water molecules received enough energy through the heat for them to change to a liquid state by unfixing themselves from their fixed positions.
Ice is the solid phase of water, so it is not silicate.
