The answer is B.
Metalloids are elements that posses some of the characteristics of non-metals and also some of the characteristics of metals.
The semiconductivity property of metalloids such as Siliconium, Geranium have been leveraged to the maximum and these are used in LCD screens, televisions and many other technological appliances.
B Longitude
Explanation:
The line of longitude or longitude does not affects climates.
Climate is the weather condition over a place for a long period of time. It usually takes several years to delineate the climate of an area.
- Longitude is the distance on the earth surface that runs form east to west.
- All lines of longitude are all great circles.
- Latitude are lines from north to south on the earth surface. Only the equator is a great circle.
- Latitude affects climate. In fact based on the division of lines of latitude on can predict climatic patterns on earth.
- Proximity to water bodies also affects climatic condition because of the effect of land and sea breeze and other climatic factors.
- Elevation affects climate a whole lot. Physiography of a place determines the weather to a very large extent.

Given:
density of air at inlet, 
density of air at inlet, 
Solution:
Now,
(1)
where
A = Area of cross section
= velocity of air at inlet
= velocity of air at outlet
Now, using eqn (1), we get:
= 1.14
% increase in velocity = 
=114%
which is 14% more
Therefore % increase in velocity is 14%
Answer:
all colours are absorbed except for the colour of the filter.
Explanation:
When white light passes through a coloured filter, all colours are absorbed except for the colour of the filter. For example, an orange filter transmits orange light but absorbs all the other colours. If white light is shone on an orange filter, only the orange wavelengths will be observed by the human eye.
