Ignoring the mass of the spring, a 5 kg mass hanging from a coiled spring having a constant k= 50 n/m will have a period of oscillation of about: (a) 10 sec., (b) 5 sec., (c) 2 sec., (d) 0.1 secc., (e) 1 min.

Period of oscillation, T = 2 sec

Explanation:

It is given that,

Mass of the object, m = 5 kg

Spring constant of the spring, k = 50 N/m

This object is hanging from a coiled spring. We need to find the period of oscillation of the spring. The time period of oscillation of the spring is given by :

T = 1.98 sec

or

T = 2 sec

So, the period of oscillation is about 2 seconds. Hence, this is the required solution.

igneous rocks also form where plates converge. the subducting plate melts as it sinks into the crust of the earth, and the melt rises into the overriding plate forming volcanoes. metamorphic rocks are formed mainly in the lithosphere, wherever there is high pressure and high temperature. -woods

because if the tool that you are using is not balanced it there would be false mass.
