AnnZ [28]

Answer:

20 N/m

Explanation:

From the question,

The ball-point pen obays hook's law.

From hook's law,

F = ke............................ Equation 1

Where F = Force, k = spring constant, e = compression.

Make k the subject of the equation

k = F/e........................ Equation 2

Given: F = 0.1 N, e = 0.005 m.

Substitute these values into equation 2

k = 0.1/0.005

k = 20 N/m.

Hence the spring constant of the tiny spring is 20 N/m

How is it possible to get three precise but inaccurate measurements of the same volume of water
Lubov Fominskaja [6]
The inaccurate measurements must be similar to the other two measurements (ex; 590, 589, 599), but different from the actual volume of water. (Ex; the actual volume is let say.. 100, but you measured 50, 49, 40)

already did the work, i just need someone to see if i did the tangent line right? the line has to touch the point 0.6! thank you

The tangent looks good.

The curve is a bit crooked, at the 0.9 and 1.

But overall, cool graph.
