A spring has an unstretched length of 14 cm . When an 81 g ball is hung from it, the length increases by 6.0 cm . Then the ball

Varvara68 [4.7K]

To solve this problem we will apply the two concepts mentioned. To find the constant we will apply Hooke's law, and to find the period we will apply the relationship between the mass and the spring constant. Let us begin,

PART A) For this section we will use Hooke's law. In turn, since the force applied is equivalent to weight, we will use Newton's law for which weight is defined as the product between mass and gravity. This weight is equal to the Spring Force.

$F = k\Delta L$

Here,

k = Spring constant

$\Delta L$ = Displacement

F = Force, the same as the Weight (mg)

Then we have that

$mg = k\Delta L$

$k = \frac{mg}{\Delta L}$

$k = \frac{9.8*0.081}{0.06}$

$k = 13.23N/m$

Therefore the spring constant is 13.23N/m

PART B) To find the period of oscillation, the relationship that allows us to find is given by the following mathematical function,

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

Here

m = mass

k = Spring constant

Replacing,

$T = 2\pi \sqrt{\frac{0.081}{13.23}}$

$T = 0.491s$

Therefore the period of the oscillation is 0.491s

How does a metamorphic rock become an igneous rock?

Oksana_A [137]

Answer:

If the newly formed metamorphic rock continues to heat, it can eventually melt and become molten (magma). When the molten rock cools it forms an igneous rock. Metamorphic rocks can form from either sedimentary or igneous rocks.

In what sense did the flappers dressand dance represent a display of freedom

pishuonlain [190]

Answer:

Flappers are symbols of the Thundering Twenties, the social, political disturbance and expanded transoceanic social trade that followed the finish of World War I. Flappers were viewed as reckless for wearing inordinate cosmetics, drinking liquor, smoking cigarettes in broad daylight, driving vehicles and treating sex nonchalantly. They guaranteed that the flappers' dresses were 'close to exposure', 'nervy', 'foolish', and unintelligent.
