Answer:
Greyfields are vacant commercial spaces and empty shopping malls.
Explanation:
Greyfields are basically large objects, usually, ones that were accomodating commercial entities like shopping malls. Because of multiple factors, those shopping malls and other types of commercial entities have closed, mostly because they have been outcompeted by more modern malls that were more attractive to the consumers.
Because they tend to be surrounded by asphalt, and the concrete dominates in the structure, they have been given the name ''grayfields''. Even though they stay unused in the urban landscape, they often offer every condition for a mall to be restarted, as the facilities are there, they tend to have a good location and are well connected with infrastructure.
Answer:
C. <ISN and <TSW
D. <TSN and <ISW
Explanation:
When two straight lines intersect each other, the two pairs of the opposite angles formed are called vertical angles.
In the figure given, we have two straight lines, NW and IT, which crosses each other. They form two pairs of opposite angles. They are:
<ISN and <TSW;
<TSN and <ISW.
These pairs of angles formed are vertical angles.
Answer:
Explanation:
The refractive index of the suspected glass can be known by using the backe- line method. This process takes place in a petrographic microscope. In this method an oil comparable to the refractive index of the glass is used. At a point when the refractive index of the glass becomes equal to that of the oil in which it is immersed the yellow line under the observation of the plane polarized light gets disappeared. This method can be used to identify the refractive index of the suspect glass and comparing it with the source of origin or sample glass.
