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

<em><u>Explanation </u></em>

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, <u>plugging w = 2.0</u> 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.

If the area of a trapezoid is 28 m with a height of 14 m in with one of the base being 1 m to find the length of the second face
In-s [12.5K]
The area of a trapezoid is basically the average width times the altitude, or as a formula:
Area = h ·

b 1 + b 2
2


where
b1, b2 are the lengths of each base
h is the altitude (height)
Recall that the bases are the two parallel sides of the trapezoid. The altitude (or height) of a trapezoid is the perpendicular distance between the two bases.

In the applet above, click on "freeze dimensions". As you drag any vertex, you will see that the trapezoid redraws itself keeping the height and bases constant. Notice how the area does not change in the displayed formula. The area depends only on the height and base lengths, so as you can see, there are many trapezoids with a given set of dimensions which all have the same area.
