Answer:
P = 1000000[Pa] = 1000 [kPa]
Explanation:
To solve this problem we must use the definition of pressure, which is equal to the relationship of force over area.
where:
P = pressure [Pa] (units of pascals)
F = force = 100 [N]
A = area = 100 [mm²]
But first we must convert the units from square millimeters to square meters.
Now replacing:
Ways carbon is added to the atmosphere is through the respiration of animals, the decay of plant matter, combustion of organic materials, and volcanic eruptions.

1. Approximately how many people watch the March Madness tournament? There are more than 140 million that watch March Madness.
The left end should the fulcrum be placed is 29.8 cm.
What is fulcrum?
The lever's pivot point is known as a fulcrum. You probably first came across a fulcrum on the playground, directly beneath the see-saw. Any general prop as well as support was referred to as a fulcrum in the 17th century. Thanks to physics class, it now has more scientific connotations. However, the term "fulcrum" is still frequently used to refer to something that is central to an event or activity, as in "the fulcrum of a debate." Who is the father who arranges everyone's playdates? He serves as the focal point of the playground social group.
counter clockwise moments = clockwise moments
(0.055 kg * x) + (0.120*(x-25)) = 0.110 kg * (50-x)
0.055x + 0.12x - 3 = 5.5 - 0.11x
x = 29.8 cm

In this system we have the conservation of angular momentum: L₁ = L₂
We can write L = m·r²·ω
Therefore, we will have:
m₁ · r₁² · ω₁ = m₂ · r₂² · ω₂
The mass stays constant, therefore it cancels out, and we can solve for ω<span>₂:
</span>ω₂ = (r₁/ r₂)² · ω<span>₁
Since we know that r</span>₁ = 4r<span>₂, we get:
</span>ω₂ = (4)² · ω<span>₁
= 16 </span>· ω<span>₁
Hence, the protostar will be rotating 16 </span><span>times faster.</span>
