If this synoptic chart were created in a GIS, several layers of data would have
(1 x 6 = 6)
been used to create it.
6.1
Name at least four layers that are needed to show all the information on
this map
(4 x1 = 4)
Which two of the following kinds of data are used: raster, vector or
attribute?
(2x1=2)
6,3 Suggest one benefit of having the layers used for this map in a GIS.(1 x 2 =2)

Alinearly polarized electromagnetic wave has an average intensity of 196 w/m^2. this wave is directed towards two ideal polarizers (in real polarizers, transmission is also effected by reflection and absorption). polarizer a is oriented with its transmission axis at an angle of θ_1=20.8∘ with the incident electric field. polarizer b has its axis at an angle of θ_2=63.0∘ with the incident electric field. what is the average intensity of the wave after it passes through polarizer a? what is the average intensity of the wave after it passes through polarizer b? suppose that the two polarizers a and b are interchanged. what would the average intensity be after passing through both polarizers?

Point charges q1 = 51 µc and q2 = −27 µc are placed 1.0 m apart, with q2 on the right. what is the force (in n) on a third charge q3 = 19 µc placed midway between q1 and q2? (assume the positive direction is to the right. indicate the direction with the sign of your answer.)
