The instrument that measures wind is called anemometer. Anemometer not only measures wind, but also, this measures the direction of the wind. And anemometer is also a common device used in a station weather. It is dervived from the greek work anemos which means wind.
Answer:
Frequency = 2Hz
Explanation:
In simple harmonic motion,
Frequency is given by the formula;
f = (1/2π)√(k/m))
Where,
k is spring constant and
m is mass
Now, the question says there are 4 suspension springs with each having a spring constant of 47100 N/m. Thus, the total amount of spring constant will be;
K_total = 4 x 47100 N/m = 188,400 N/m
Thus, let's now find the frequency since we have m = 1190kg
f = (1/2π)√(k/m)
f = (1/2π)√(188400/1190)
f = (1/2π) x 12.5825
f = 0.159149 x 12.5825 = 2 Hz
Answer:
The electrons in oxygen are paired while in nitrogen, they are not.
Explanation:
To analyse this we start with writing out the ground state electronic configurations for both elements.
Oxygen: 1s²2s²2p4 meaning the p subshell has the following arrangement of electrons ↑↓ ↑ ↑
Nitrogen : 1s²2s²2p³ meaning the p subshell has the following arrangement of electrons ↑ ↑ ↑
Clearly the paired electron in oxygen will be experiencing repulsion from the electron it shares an orbital with causing it to be removed easily. The electrons in nitrogen are unpaired, each orbital is singly occupied
Answer:
<em>x=10.39 m/s</em>
<em>y = 6 m/s</em>
Explanation:
<u>Components of a Vector</u>
A vector can be expressed in several forms, including the rectangular and the polar form.
The rectangular form uses the x-y coordinates of the vector, being the right and up directions considered as positive.
The polar form uses the magnitude r and the angle it forms with the positive x-direction.
Given the polar form (r,θ), we can calculate the rectangular coordinates as follows:
The soccer ball is kicked with an initial speed of v=12 m/s and an angle of 30 degrees. Thus the horizontal and vertical components are:
x = 10.39 m/s
y = 6 m/s
