S~ cientists publish their original research in scientific journals, which are fundamentally different from news magazines. The articles in scientific journals are not written by journalists – they are written by scientists. Scientific articles are not sensational stories intended to entertain the reader with an amazing discovery, nor are they news stories intended to summarize recent scientific events, nor even records of every successful and unsuccessful research venture. Instead, scientists write articles to describe their findings to the community in a transparent manner.
An analog signal is a continuous signal whereas Digital signals are time separated signals. Analog signal is denoted by sine waves while It is denoted by square waves Analog signals are suited for audio and video transmission while Digital signals are suited for Computing and digital electronics.
Hope this helps :) have good day/night
I have no idea can someone help
Answer:
see that the correct one is D
Explanation:
In this problem the satellite is subjected to the universal force of attraction
F = G M m / r²
using Newton's second law with centripetal acceleration you can find the angular velocity of the satellite
F = m a
F = m w² r
G M / r³ = w²
and w = 2π / T
In this case, the satellite is in a two-dimensional movement, where the free fall of the satellite is compensated by the horizontal displacement, for which it is always at a distance from the earth, remaining at the same point.
When reviewing the different statements we see that the correct one isD
