How much displacement will a spring with a constant of 120N / m achieve if it is stretched by a force of 60N?

Explanation:

There's a formula for this:

F being force, k being the spring constant, and displacement being the change in x

We are given the force and the spring constant, so this is essentially isolating the Δx term. Do 60N/120N per meter. The newtons cancel out and you get a final answer of Δx = 0.5 meters

when heated, the valance electrons increased their speed and transferred the heat from electron to electron.   i just took the test.
