Answer:
The name of the force is elastic (spring) force
Explanation:
The elastic force which is the restoration force of an elastic (spring like) object that tries to return to its initial non-stretched state built up by the pulling of the bow by the archer (using the muscles) pushes on the arrow which the archer releases the same time he leaves the bow string, and the arrow flies in the direction already pointed by the archer
The arrow ultimately falls down due to gravity forces that acts on all objects within the Earths gravitational field. However due to the speed of constant horizontal speed of the arrow and increasing downward speed of the due to the gravity force, the falling of the arrow looks disappointing.
Well, it's actually optical "density", but I understand
what you're getting at.
That phenomenon is called "refraction".
It happens with any wave motion. It's very prominent in the
progress of seismic waves, radio waves, sound waves etc.
Answer:
A neutron star.
Explanation:
A 10-solar-mass main-sequence star will produce a neutron star.
Neutron star is a celestial object having very high density, very small radius of 30 kilometers and predominantly made up of closely packed neutrons. They are formed due to gravitational collapse of a massive star when it runs out of fuel.
