If you have a neutral atom (like you normally would) then the number of electrons is equal to the number of protons. If you had more electrons then the charge would be negative. In this case, you would have 20 electrons.
Hypothesis testing is a formal procedure for investigating our ideas about the world using statistics. It is most often used by scientists to test specific predictions, called hypotheses, that arise from theories.
There are 5 main steps in hypothesis testing:
State your research hypothesis as a null and alternate hypothesis.
Collect data in a way designed to test the hypothesis.
Perform an appropriate statistical test.
Decide whether to reject or fail to reject your null hypothesis.
Present the findings in your results and discussion section.
Though the specific details might vary, the procedure you will use when testing a hypothesis will always follow some version of these step

Answer:
It's the first option. A distance between two similar points on a wave of light.
Explanation:
On a wavelength chart, where you measure the rate at which the light travels at its distance from the source. You have two points to compare to.
Wind blows__wind energy ____causing the turbine to turn, rotating shaft works pump__mechanical___energy.
Motion of water moving up from well___kinetic energy___energy.
Water in tank which is positioned 5 feet above the ground level______potential energy
Explanation:
Wind has in it wind energy which is then used to rotate the turbine shaft which is a form of mechanical work and hence possess mechanical energy
Moving water posses kinetic energy and when this water is kept at some height it possess potential energy
Answer:
The answer is
<h2>1.30 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula

From the question
mass of object = 6.9 g
volume = final volume of water - initial volume of water
volume = 30.4 - 25.1 = 5.3 mL
It's density is

We have the final answer as
<h3>1.30 g/mL</h3>
