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.

Tons of wind, rain, thunder. Stuff like that.
The third choice: it is equal to the total mass of glucose and oxygen formed because during the process of photosynthesis the reactants need to be equal to the total mass of the product which includes both sugar (glucose) and oxygen.
Answer:
The temperature of the mixture is 60°C
Explanation:
We can write the energy of water as follows:
E = m×C×T
<em>Where E is energy in Joules, m is mass of water, C is specific heat of water = 4.184J/g°C and T is temperature</em>
<em />
Replacing fot both samples:
E = 20g×4.184J/g°C×30°C
E = 2510.4J
E = 40g×4.184J/g°C×75°C
E = 12552J
The total energy of the mixture is 12552J + 2510.4J = 15062.4J
Mass = 60g:
15062.4J = 60g×4.184J/g°C×T
60°C = T
<h3>The temperature of the mixture is 60°C</h3>
Answer:
When published, each article expands the library of scientific literature available to all scientists and contributes to the overall knowledge base of the discipline of science. They report new research for the first time.
