Answer:
If I add sugar or salt, the water's density will increase.
Explanation:
Density is the relation between mass and volume. We can represent it with the formula δ= m/v. Where δ stans for density, m for mass, v for volume.
If we add salt or sugar, we increase the mass, but the volume is the same. As a result, the density will increase.
We can use numbers to understand it better.
Suppose that before adding salt or sugar, the mass is 1 g and the volume is 1 l
δ= 1g/l1t
δ= 1 g/lt
Now, if we add sugar or salt, the mass increases. Suppose that we have 2g of mass and the volume is the same, 1l.
δ= 2g/1lt
δ= 2g/lt
We can see that the density increased when the mass increased.
Strenuous muscular is just a fancy way to say exercise. As the muscles are used more often the need more oxygen, so that is why your breathing rate increases while doing "exercise".
The right option is; B. What is the effect of plastic bags on birds?
The scientific process is a systematic method of exploring observations and answering questions. Asking a question is the first part of the scientific process (followed by research, hypothesis, experiment, data/analysis and conclusion). A question that can be answered using the scientific process must have some answers, must be testable through an experiment and must lead to a hypothesis that is confirmable. From the question, ‘’what is the effect of plastic bags on birds’’ is a question that have some answers and can also be tested by someone through an experiment.
The energy of the electrons increases
