A spring suspended vertically is 11.9 cm long. When you suspend a 37 g weight from the spring, at rest, the spring is 21.5 cm lo

Naddika [18.5K]

Answer:

Time period of oscillations is 0.62 s

Explanation:

Due to suspension of weight the change in the length of the spring is given as

$\Delta L = L_f - L_i$

$\Delta L = 21.5 - 11.9 = 9.6 cm$

now we know that spring is stretched due to its weight so at equilibrium the force due to weight is counter balanced by the spring force

$mg = kx$

$0.037 (9.81) = k(0.096)$

$k = 3.78 N/m$

Now the period of oscillation of spring is given as

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

Now plug in all values in it

$T = 2\pi \sqrt{\frac{0.037}{3.78}}$

$T = 0.62 s$

The rocky planets are made of material that is much (mire/less) dense than the outer planets.

IRINA_888 [86]

The outer planets (Jupiter, Saturn, Uranus, Neptune) are called the "<u>GAS</u> giants".

The rocky planets are called "rocky" because they're made of <u>ROCK</u>.

Does this help guide you to the correct choice ?

Here's another hint: The MOST dense planet in our solar system, the one we call "Earth", is one of the 'rocky planets'.

Nataly_w [17]

Answer:

63

Explanation:

You first have to add all the numbers together.

22+72+79+72+70 = 315

You divide the total by the amount of numbers (5)

315/5 = 63

The mean is 63
