If the work done to stretch an ideal spring by 4.0 cm is 6.0j, what is the spring constant (force constant) of this spring?

Spring constant or the force constant, k = 7500 N/m.

Explanation:

Given that,

Energy stored in the spring, E = 6 J

Stretching in the spring, x = 4 cm = 0.04 m

To find,

The spring constant (force constant) of this spring.

Solution,

We know that the work done by the spring when it is stretched is given by :

k is the spring constant

k = 7500 N/m

So, the spring constant (force constant) of this spring is 7500 N/m.

a.   mass number from atomic number

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.

not copied too! hope this !
