Remote sensing is the acquisition of information about an object or phenomenon without making physical contact with the object.
The methods of sensing are based on electromagnetic energy released or reflected from Earth's surface at some range above the earth. Remote sensors can be either passive or active depending upon the source of electromagnetic energy.
Earth's surface and atmosphere may involve the use of any of the instruments depending on the type of research to be done.
There are mainly two types of instruments used, passive and active instruments, below are some of the instruments used;
Ozone and Aerosol LiDAR. Radar Wind Profiler, Radiometer, Imaging Radiometer, Spectrometer, Spectroradiometer, Radar (Radio Detection and Ranging), Scatterometer, Lidar (Light Detection and Ranging), Laser Altimeter, SAOZ Instrument.
Answer:
1. Electronegativity is the property of an atom that attracts the shared pair of an electron to itself.
2. Electronegativity increases and decrease. It increases when to you from to the side or across of a period because the number of charge in the nucleus increases. Electronegativity decreases when you move down in a group because the electrons move farther or become far from the nucleus's pull.

The answer would be new theories come up and are replaced by the older inaccurate theories. Obviously this theories are checked by scientists over and over and over again to see if they can make it more accurate and better.
There are several types of charts that can be graphed; however the given chart is an example of a (d) supply schedule
From the chart, we can see that the chart shows the amount of goods supplied when a certain demand is made, at a given price.
Take for instance,
When the price of goods is $5 and the demand is 50, the quantity supplied is 30
This is an illustration of a supply schedule
Hence, the chart is an example of a (d) supply schedule
