Answer:
Explanation:
If angle of incidence and angle of refraction be i and r respectively ,
sini / sinr = μ ( refractive index )
sin r = sin i / μ
If angle of incidence i be constant and medium becomes denser that means μ becomes higher in value , the value of sin r will be low ( because of increase in value of denominator )
As sin r decreases , r also decreases also.
Hence when medium becomes denser , angle of refraction becomes less .
The firearm is unloaded.
The ramrod establishes whether the firearm is loaded or unloaded. It thrusts the bullet down the barrel. It is marked by wrapping some tape around it ( at the muzzle end ). This is to effectively signal if the muzzleloader is empty or loaded.
Answer:
An opposing force caused by friction produced a lower acceleration than calculated.
Explanation:
This is a poorly written question.
<span>Out of the choices listed, the first one is the only one that includes
a true statement ... the greater the mass of two objects, the
greater
the gravitational attraction is between them.</span>
-- Newton's law of universal gravitation doesn't "suggest" that. It states it ...
boldly and unequivocally.
-- The law doesn't refer to the "greatness" of the mass of the two objects.
It refers to the product of their masses.
-- It's true that the law of universal gravitation can be massaged and
manipulated to reveal the existence of gravitational planetary orbits.
But there's a lot more to it than simply the masses.
For example ... the gravitational force between two objects is inversely
proportional to
(the distance between the objects)² .
It turns out that IF that exponent were not precisely, exactly 2.000000... ,
then gravitational orbits could not exist.
