pascal is the unit of pressure

The units of pressure is called derived units because it is simply derived from base unit which is distance and a derived unit which is force, which is derived from acceleration, a derived unit as well, and mass, a base unit. As we all know, work is defined as the force x distance. Thus making work a derived unit.Jun 23, 2020

Black_prince [1.1K]

Answer:

None of the animals are from the same species

Explanation:

The exact question is as follows :

Given -

Felis catus

Sylvilagus audubonii

Parus inornatus

Euarctos americanus

Check out the list of scientific names. These names all represent animals. These are all animals but they cannot reproduce to produce fertile offspring with each other.

To find - What conclusion can be drawn from the past statement?

Solution -

The conclusion we can made from past statement is that - None of the animals are from the same species

Reason -

When two members of the same species reproduce, they produce fertile offspring.

According to the scientific names of the animals, there are different genus and species names.

James Stewart, 2002 Motorcross/Supercross Rookie of the Year, is leading a race when he runs out of gas near the finish line. He

Flura [38]

We are given the coefficient of friction which is:
Cf = 0.90
The acceleration based on this would be:
a = -Cf * g
a = -0.90 * (9.81 m/s^2)
a = -8.83 m/s^2
Calculate the distance at his total stop v = 0 using the formula:
v^2 = vo^2 + 2ad
where v is final velocity = 0, vo is initial velocity = 16, d is distance
0 = 16^2 + 2 (-8.83) d
d = 14.5 m
So he is short by 0.5 m, he does not reach the finish line

A 0.14-km wide river flows with a uniform speed of 4.0 m/s toward the east. It takes 20 s for a boat to cross the river to a poi

Dmitry [639]

Answer:

The right approach is "8.1 m/s". A further explanation is provided below.

Explanation:

According to the table,

Speed of Boat

= $\frac{s}{t}$

$V_b=\frac{140}{20}$

$V_a = 4 \ m/s$

$V_B = 7 \ m/s$

Now,

⇒ $(V_{relative})^2 = (7)^2+(4)^2$

or,

⇒ $(V_r)^2=49+16$

$=65$

$V_r=\sqrt{65}$

$=8.1 \ m/s$

Which of these is outside of the solar system? A.Sun B.Galaxy C.Saturn D.Moon

Angelina_Jolie [31]

It would be the Galaxy because the solar system is just plants are stuff. But, the galaxy expands way farther out than the solar system. The galaxy is quite an interesting thing. (You should know that the galaxy is outside the solar system 0_0 )
