Answer:
The windowpanes are- transparent.
The color of the panes are due to the wavelengths of light that the glass- allows to pass through

Titty milk I think because it taste amazing so you can go 21km/h
A diverging lens is used to permit clear vision of an object placed at infinity. The focal length of the lens is -100 cm.
<h3>What is focal length?</h3>
The focal length is half of the radius of curvature of the focal lens.
By the lens maker formula,
1/f = 1/v +1/u
where, v is the image distance and u is the object distance.
Give, the object is at infinity and the image must form at 100 cm, the the focal length will be
1/f = 1/ -100 + 1/∞
f = -100 cm
The focal length must be -100 cm for the diverging lens.

Answer:
0.0979 N/c
Explanation:
Electric field, E is given as a product of resistivity and current density
E=jP where P is resistivity and j is current density
But the current density is given as
where I is current and A is area and ![A=\pi r^{2}](https://tex.z-dn.net/?f=A%3D%5Cpi%20r%5E%7B2%7D)
Substituting this into the first equation then ![E=P\times \frac {I}{\pi r^{2}}](https://tex.z-dn.net/?f=E%3DP%5Ctimes%20%5Cfrac%20%7BI%7D%7B%5Cpi%20r%5E%7B2%7D%7D)
Given diameter of 0.259 cm= 0.00259 m and the radius will be half of it which is 0.001295 m
![E=1.72\times 10^{-8}\times \frac {30}{\pi \times 0.001295^{2}}=9.79\times 10^{-2} N/c=0.0979 N/c](https://tex.z-dn.net/?f=E%3D1.72%5Ctimes%2010%5E%7B-8%7D%5Ctimes%20%5Cfrac%20%7B30%7D%7B%5Cpi%20%5Ctimes%200.001295%5E%7B2%7D%7D%3D9.79%5Ctimes%2010%5E%7B-2%7D%20N%2Fc%3D0.0979%20N%2Fc)
The answer to this question is "Buffeting". This is an unusual strong wind condition that resulted in the loss of vehicle control. This condition occurs in roads and bridges, across and along mountains that affected vehicles control. The drivers must be alert and put their full attention to overcome this condition.
