Answer: Universe.
Explanation: In addition to the solar system, the heliocentric model stated that the sun was the center of the UNIVERSE.
Every plant orbits around the sun, which makes our universe whole and bright.

(a) 0.74 m/s^2
Explanation:
There are two forces acting on the skier: the component of the weight parallel to the slope, which acts downward, and the frictional force, which acts upward along the incline.
The component of the weight parallel to the inclined plane is:

where m is the mass of the skier,
and
.
The frictional force is instead

is the coefficient of friction for waxed wood on wet snow.
If we apply Newton's second law, we can write that the net force must be equal to the product of mass per acceleration:

And symplifying m, we can find the acceleration:


(b) 
Explanation:
This time, the skier is moving at constant velocity. Therefore, the acceleration is zero (a=0) and Newton's second law becomes:

By simplifying, we get

From which we can find the angle at which the skier could coast at a constant velocity:

Answer:
If you take the first example of the walk around the desk, it should be apparent that sometimes the distance is the same as the magnitude of the displacement. ... Since the displacement is measured along the shortest path between two points, its magnitude is always less than or equal to the distance.
Neutrons
Explanation:
Atoms of the same elements are called isotopes. They differ from other atoms in the number of neutrons they posses. They share the same chemical properties but only differ with regards to their mass number.
- Isotopy is a phenomenon whereby an atom of an element exist in more than one form but they have the same atomic number.
- Atoms of such element only differ in the number of neutrons they contain.
- Since the mass number of an atom is the sum of protons and neutrons, they differ in this number too
- Isotopes have the same chemical properties.

Answer:
after 6 second it will stop
he travel 36 m to stop
Explanation:
given data
speed = 12 m/s
distance = 100 m
decelerates rate = 2.00 m/s²
so acceleration a = - 2.00 m/s²
to find out
how long does it take to stop and how far does he travel
solution
we will apply here first equation of motion that is
v = u + at ......1
here u is speed 12 and v is 0 because we stop finally
put here all value in equation 1
0 = 12 + (-2) t
t = 6 s
so after 6 second it will stop
and
for distance we apply equation of motion
v²-u² = 2×a×s ..........2
here v is 0 u is 12 and a is -2 and find distance s
put all value in equation 2
0-12² = 2×(-2)×s
s = 36 m
so he travel 36 m to stop
