Explanation:
we can use the formula F = ma
hence,
F = 20 × 80
F = 1600 Newtons
hope this helps.
Answer:
Prefixes often added to S. I. units because this system is globally accepted
Explanation:
S.I. is abbreviation for international system. International system of units is globally accepted. Thus, on international platform all physical quantities should be represented in S.I. system of units.
There are 7 fundamental units in S.I system 2 supplementary and many derived units are included in S.I. system.
While using another system of units create confusion on international level. Thus, to avoid confusion all prefix are added to S.I. system.
We know, f = ma
Here, m = 100 kg
a = 20 m/s²
Substitute their values,
f = 100 * 20
f = 2000 N
In short, Your Answer would be 2000 N
Hope this helps!
Astronomers thought that a nova was a new star, appearing for the first time in the heavens, today we know that it is as a binary star system.
<h3>What is the binary star system about?</h3>
A binary star system is known to be one where one star is known to be called a white dwarf and there is a mass that is said to be transferred to it
A binary star is known to be a kind of a system that is composed of two stars that are known to be gravitationally held together to and in orbit near each other.
Note that Binary stars in the night sky are ones that are often seen as a single object and thus Astronomers thought that a nova was a new star, appearing for the first time in the heavens, today we know that it is as a binary star system.
