Answer:
The answer is: a column that shows how the dependent variable changes.
Explanation:
An experiment is <em>a process that is carried out by a researcher in order to find out whether his hypothesis is valid.</em> In order to conduct a proper experiment, it is very important to include both the <u>"dependent"</u> and <u>"independent" variables.</u>
A dependent variable refers to <u>the variable that changes in response to the presence of an independent variable.</u> On the contrary, an independent variable is <u>the variable (such as factors) that is being changed in order to control the experiment. </u>
Remember that<em> independent variables do not depend on other factors.</em> Thus, i<u>t is only the dependent variable's change that matters in an experiment.</u>
This is the reason why Dalila needs to have a column that shows the dependent variable changes (and not the independent variable changes).
PE = mgh
137200 = mg x 200
686 = mg
686/9.81 = m
m = 69.9286.... (idk how many decimals / sig. figs. you need)
The answer is A) seconds hand
Answer with Explanation:
We are given that
Initial speed=
a.
Final velocity of ball=

g is negative because the ball is going against to gravity.




Using the formula


a.The ball rise upto height 18.4 m
b.It take 1.94 s to reach its highest point.
c.Initial velocity=0,s=18.4 m







Using the formula
