A block of mass 0.404 0.404 kg is hung from a vertical spring and allowed to reach equilibrium at rest. As a result, the spring

VARVARA [1.3K]

To solve this problem it is necessary to apply the concepts related to the Force from Hook's law as well as the definition of the period provided by the same definition.

We know that the Force can be defined as

$F = xk \rightarrow mg = kx \Rightarrow k = \frac{mg}{x}$

Where

k = Spring constant

x = Displacement

g = Gravity

m = mass

At the same time the period of a spring mass system is defined as

$T = 2\pi \sqrt{\frac{m}{k}}$

Where

m = Mass

k = Spring constant

Our values are given as,

m = 0.404kg

x = 0.666m

Replacing to find the value of the Spring constant we have that

$k = \frac{mg}{x}$

$k = \frac{(0.404)(9.8)}{0.666}$

$k = 5.944N/m$

Now using the formula of the period we know that

$T = 2\pi \sqrt{\frac{m}{k}}$

$T = 2\pi \sqrt{\frac{0.404}{5.944}}$

$T = 1.638s$

Finally, if the oscillation was 0.359m

The maximum height will be determined by the total length of that oscillation being equivalent to

$h=2a$

$h = 2*0.359$

$h = 0.718m$

amid [387]

A series of processes on Earth's surface and in the crust and in the mantle that slowly change rocks from one kind to another is called the rock cycle. This cycle is a group of changes. We all know that the rock has 3 kinds which are igneous rocks, the sedimentary rocks, and the metamorphic rocks. The igneous rocks in the rock cycle can change to the sedimentary rocks or to the metamorphic rocks. The sedimentary rocks can also change to the igneous rocks or to the metamorphic rocks. The metamorphic rocks can change to the igneous rocks or to the sedimentary rocks. All depends on the process it undergoes and the factors present to affect the change it undergoes.
