____ is undeniably accepted by scientists all over the world as the primary language of science.
faust18 [17]

Answer:

Latin

Explanation:

In order for the scientists to have a common and official name for a particular thing that can be understood by every scientist in the world, a single language has been established for the purpose. The language chosen is the Latin language. The official scientific names are given in this language, so it is a necessity for the scientists to know and understand this language. The terms that are commonly used are regional, and they come in many different languages, which is why this language has been chosen. Occasionally, the ancient Greek language is used as well, though much less than the Latin.

Naya [18.7K]

In SBc galaxies, both the arms and the bar are highly resolved into star clouds and stellar associations. The arms are open in form and can start either at the ends of the bar or tangent to a ring.

<h3>Is the Milky Way a SBc galaxy?</h3>

Originally thought to be a hubble type Sb or Sc (Sbc), astronomers now believe that the Milky Way is has a central bar and is therefore a loosely wound, barred spiral galaxy – Hubble type SBbc.

<h3>What is the difference between an SBc galaxy and an Sc galaxy?</h3>

Sa (and SBa) galaxy types have tightly wound arms and large central bulges.

Sc's (and SBc's) have loosely wound arms and a small central bulge.

A horse performs 2600 joules of work pulling a wagon for 13 seconds. What is the horse's power? 33800 W 200 W 0.005 W 2600 WA ho
tensa zangetsu [6.8K]

Answer:

200 W

Explanation:

The power is given by the ratio between the amount of work done and the time taken to perform the work:

P=\frac{W}{t}

where in this problem we have

W = 2600 J is the work done

t = 13 s is the time taken to do the work

Substituting the numbers into the equation, we find

P=\frac{2600 J}{13 s}=200 W
