What are the units for the spring constant, k? a. newton meters b. newton seconds c. newtons/meter d. newtons/second e. newtons/seconds2

C. N/m (newtons/meter)

Explanation:

Since the equation for potential energy for a spring is PE = 1/2kx², after you know k and x, you will get an answer in Joules.

Please let me know if you want me to explain further!

Thanks!

Option (c)

Explanation:

The spring constant is defined as the force per unit length of compression or expansion in spring. So it's unit is newton per metre.

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.
