Answer:
follows are the responses to the given question:
Explanation:
The kinetic energy of every object moving. any entity lifted against the strength of gravity stores elastic potential of gravity.
Its total power of an independent device stays constant underneath the Mass conservation on Energy and it is, the kinetic energy plus potential energy is just like a fixed . So, if KE improves, it is valid that PE declines.
If the PE is now at least then KE has been at the highest. It is also valid that KE is reduced as PE is increased as well as the maximum PE, the minimum KE.
Answer: The orbital speeds of stars far from the galactic center are surprisingly high.
Dark matter is a type of matter, whose composition is unknown and which corresponds to 80% of the matter in the universe. Its name refers to the fact it does not emit or interact with any type of electromagnetic radiation, being completely transparent throughout the electromagnetic spectrum.
<h2>However,
it interacts with the known matter through gravity. </h2><h2 />
In this sense, it is believed that the Milky Way has 90% dark matter and only 10% ordinary matter (known matter). Because, like gravity, dark matter can not be observed directly, however its existence is inferred through the movement of the stars far from the center and the cosmic dust within the galaxy.
Answer:
pretty sure for this one, "if the density affected the liquid's ability to retain heat."
Explanation:
a hypothesis should be in "if, then, because.." format, and while this bit of the passage doesnt include all three, it does include one! that bit of the passage would be an incomplete hypothesis.
Answer:
Explanation:
Apply a known AC voltage to the primary coil. Call it V₁
Measure the resultant voltage on the secondary coil. Call it V₂
If N₁ is the number of turns on the primary coil
and N₂ is the number of turns on the secondary coil
N₂ / N₁ = V₂ / V₁
N₂ = N₁V₂ / V₁
Answer:
I think A
Explanation:
because I don't think a unknowned number can be a division problem
