Answer:
The oldest maps were made by hand of course, and were based on fairly crude measurements of paces, strides and the like and directions only loosely related to NEWS. Clocks helped (as with navigation, latitude could be estimated by seeing what stars were above the horizon (or how high the sun seemed at its zenith), but longitude needed to know when they were seen).
Modern maps have the extraordinary advantage of precise locations of points, and even the benefit of direct overhead observation, and are no longer hand drawn.
Explanation:
Answer:Functional magnetic resonance imaging or functional MRI (fMRI)
Explanation:Functional magnetic resonance imaging or functional MRI (fMRI) is a technique used to measure activities that occurs in the brain by detecting how the blood flow changes. It is based on the fact that blood flow and neuronal activation occur together.
Answer:
Communication has a synchronous temporal structure
Explanation:
Temporal Structure communication means a communication can be synchronous or asynchronous. Real-time communication is a synchronous type. It is usually face to face or phone calls, or instant messages as these all occur in real time.
If messages have delay between them, it is a asynchronous type of communication, like an email or voice mail. Thus, online communication has temporal structure communication can be both synchronous or asynchronous as it can be real time in case the chats are instant online and in case of emails, it is asynchronous.
Answer:
In 1 hour it will cover a distance of 15°
Explanation:
We know that for each rotation earth takes 24 hour
In 24 hour its travels 360° of rotation
We have to find how much we travel in 1 hour in degree
We know that 1 rotation = 360° which is completed in 24 hours
So distance traveled in 1 hour in degree will be = 
So in 1 hour it will cover a distance of 15°
