A2.0 kg hanging mass stretches a coiled spring by 0.15 m. the spring constant, k, is: (a) 0.075 n/m, (b) 2.9 n/m (c) 131 n/m, (d) 1,742 n/m, (e) none of the above.

C

Explanation:

Givens

m = 2 kg

F = 2 * 9.81

F =  19.62 N

x = 0.15 m

Formula

F = k*x

Solution

19.62 = k*0.15

k = 19.62/0.15

k = 130.8 which rounded to the nearest given answer is C

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.
