-- There is no need to develop the pictures. They are available immediately in a digital camera.
-- There is no change in the teacher from one picture to the next.
-- The distance the watermelon falls from the teacher in each new picture is more in each picture than in the picture before it. (C)
Testable: Able to be tested or tried.
<em>ex. An example of a testable hypothesis is, Students who attend class more have higher grades, while those who skip have lower grades. </em>
Data: Data is the items of information that represent our analyze, or our findings in an experiment.
<em>ex. An example of Data, is the results of information collected for a research paper.</em>
Evidence: Evidence is information that helps show whether a proposed idea is valid.
<em>ex. We can use evidence to help support our point and strengthen our findings with reasoning.</em>
Theory: Theory is an explanation of something in the natural world that can be tested and gives us the same results each time. A proven hypothesis.
<em>ex. Examples of scientific theories are gravitation, evolution, and plate tectonics. </em>
Hypothesis: A hypothesis is a theory or question that can be tested through study and experimentation. It has more reasoning to it than a simple guess, but not enough information to be a theory.
<em>ex. An example of a possible hypothesis is, If we play music while working on homework, the participant's perfomance will increase.</em>
Answer: 58,045,522,878.8 meters
Explanation:
Ok, the data we have is
Period = T = 88 days
Radial acceleration = ar = 3.96x10^-2 m/s^2
And we know that the equation for the radial acceleration is:
ar = v^2/r = r*w^2
Where v is the velocity. r is the radius and w is the angular velocity.
And we know that:
w = 2*pi*f
where f is the frequency, and:
T = 1/f.
Then we can write:
w = 2*pi/T
and our equation becomes:
ar = r*(2*pi/T)^2
Now we solve this for r.
First we need to use the same units in both equations, so we want to write T in seconds.
T = 88 days,
A day has 24 hours, and one hour has 3600 seconds:
T = 88*24*3600 s =7,603,200s
Then:
3.96x10^-2 m/s^2 = r*(2*3.14/7,603,200s)^2
r = (3.96x10^-2 m/s^2) /(2*3.14/7,603,200s)^2 = 58,045,522,878.8 meters
<span>NaCH is not an element, it is a compound. An element can be found and identified on the periodic table to elements. A compound is a combination of two of more elements. NaCH is composed of three elements: Na (sodium), C (carbon) and H (hydrogen), making it a compound.</span>
Nuclear size are measured in a unit called fermi
Magnetism at the centre of a bar magnet is zero, because there is no magnetism at all in the centre
Hope this helps :)
