Answer:
A chemical reaction is a process in which the chemical bonds of a substance are broken or rearranged. One or more substances are formed with different properties because of this chemical reaction. Examples of chemical reactions are rust, combustion, and oxidation.
Answer:
You determine the net force of an object by adding up all of the individual forces.
Explanation:
If N is the number of forces acting on the body, the net force formula is:
= + + ....+
Where , , and as forces acting on a body.
When a body is at rest, the net force formula is given by
Fa = Applied force and
Fg = Gravitational force.
<u>Example:</u>
A truck is standing still and a force of 70 N is applied on it. If the frictional force is 20 N, then what will be the net force?
Solution:
Given
Applied force Fa = 70 N
Frictional force Ff = 20 N
The net force formula is given by
FNet = Fa + Ff
FNet = 70 + (-20)
FNet = 50 N
Therefore, the net force is 50 N
A would because its amplitude is higher than B's Hope this helps :D
Answer:
The answer to your question is: letter B
Explanation:
The information given is showing us three kinds of carbons and their respective number of protons and neutrons. Now, let's analize the options given:
A.)Carbon Bond Types This option is about trhe kind of bonds carbon is able to form like single, double or triple and is different from the information descrive above. So ,this option is incorrect.
B.)Carbon Isotopes is option is about the carbon atoms that have the same number of protons and different amount of neutrons exactly as it is describe above, to this option is correct.
C.)The Carbon Cycle
this option is about how carbon goes from one kind of matter to another and is completely different to the description given above, so this option is incorrect.
D.)Chemical Reactions this option is about reactants that after a process give products they could be from carbon -12, carbon-13 or carbon-14 and other elements, so this option is different from the description given above.
This question is more for Biology than Chemistry, but the role of producers is to make energy (food) to be consumed. In a pyramid diagram, the producers would be at the bottom. Now going up the pyramid, the primary conumers are the first to consume producers and obtain energy from them. As you go up the pyramid, the secondary consumers will consume the primary consumers as a way to obtain energy, and the same goes for tertiary consumers towards secondaries.
As you go up the energy pyramid, you will notice a trend that there is less energy being obtained from each consumer. In other words, the producers will ALWAYS have more energy than the tertiary consumers.
I hope this answers your question.
