So there's no way for us to guide you to select the correct one, and
if I want to answer this question and scoop up a few points, I have to
invent an answer from scratch.
On a speed/time graph, a VERTICAL line segment represents something
that's physically impossible.
The top of the line segment is a speed that's faster than the bottom
of the segment, but the times are both the same.
A change of speed that takes no time would correspond to infinite
acceleration. That just simply sounds wrong, and it is. Can't happen.
Answer:
1.7N
Explanation:
Force = kx
Where x = spring compression and
K = spring constant
K =85N/m
x = 2.0cm / 100
= 0.02m
Force = 85 x 0.02
= 1.7N
Depends on how well built he is probably for the average American 8 MPH
1.) Its a controlled experiment because both groups A and B get the equal mount of sunlight and water. The manipulated variable would be the fertilizer.
2.) Because a theory must consists of more than experiment before it can actually be considered a theory. It must be performed multiple times.
3.) Because if the growth was on the B spot, the graph would be a bar graph because the growth would still increase by each day.
