10. A weight hangs on a spring. The vibration period of that weight is the time in which it makes a complete cycle in motion. Su

Alenkinab [10]

The vibration period of the spring will be 0.2 seconds

Explanation

The relationship between the vibration period "T" (in seconds) and the weight "w" (in kilograms) is given by...

$T= 2\sqrt{\frac{w}{200}}$

Given that, the weight(w) = 2.0 kilograms

So, plugging w = 2.0 into the above equation, we will get...

$T= 2\sqrt{\frac{2.0}{200} } \\ \\ T= 2\sqrt{\frac{1}{100} }\\ \\ T= 2*\frac{1}{10}\\ \\ T= \frac{1}{5}=0.2$

So, the vibration period of the spring will be 0.2 seconds.

Agata [3.3K]

Answer:

$\frac{60}{13}$

[improper fraction]

$4 \frac{8}{13}$

[mixed fraction]

$4.\overline{615384}$

[decimal]

Explanation:

$\frac{\frac{a}{b}}{\frac{c}{d}} = \frac{a}{b} × \frac{d}{c} = \frac{ad}{bc}$

12/13 divided by 3/15 →

$\frac{\frac{12}{13}}{\frac{3}{15}}$ →

$\frac{12}{13} × \frac{15}{3}$ →

$\frac{12}{13} × 5$ →

$\frac{60}{13}$
