The correct hierarchy would be
-<span>A solar system is a collection of planets, their moons, and other objects in orbit around a central star.
</span><span>-A galaxy refers to all existing matter, energy, and space that is held together by gravity</span>
KE=1/2mass time velocity squared so 15kg x 20^2=6000
Answer:
Here are all the possible meanings and translations of the word gravitational energy. Gravitational energy is the potential energy associated with the gravitational field. This phrase is found frequently in scientific writings about quasars and other active galaxies. Quasars generate and emit their energy from a very small region.
Explanation:
Answer:
Magnitude = 3.64 × 
စ = 43.9°
Explanation:
given data
ship to travel = 1.7 × kilometers
turn = 70°
travel an additional = 2.7 × kilometers
solution
we will consider here
Px = 1.7 ×
Py = 0
Qx =2.7 × cos(70)
Qy= 2.7 × sin(70)
so that
Hx = Px + Qx ............1
Hx = 2.62 ×
and
Hy = Py + Qy ..........2
Hy = 2.53 ×
so Magnitude = 
Magnitude = 3.64 ×
so direction will be
tan စ = Hy ÷ Hx ......................3
tan စ = 
tan စ = 0.9656
စ = 43.9°
Well basically in physics and chemistry, the law of conservation of energy states that the total energy of an isolated system remains constant, it is said to be conserved over time. This law means that energy can neither be created nor destroyed, it can only be transformed or transferred from one form to another.
Hope this helps (:
