Answer:
The velocity of the pin is opposite its acceleration on the way up.
(d) option is correct.
Explanation:
when the juggler throws a bowling pin straight in the air, the acceleration working on the pin is in the downward direction due to the gravitational force of the earth.
According to Newton's Universal Law of Gravitation
''The gravitational force is a force that attracts any objects with mass''
Answer:
The magnetic force can act from a distance because of the magnetic field that is created around it. It can be defined as imaginary lines around the magnet upto which it has magnetic force.
If a piece of iron is put into the magnetic field but has a slight distance from the magnet, it will be pulled towards the magnet because it is in its magnetic field.
The south pole and the north poles of the magnet has effect on each other. Same poles repeal each other and opposite poles attract each other resulting in forming a field of attraction or repulsion.
The imaginary lines created are known as magnetic field which is responsible for the magnetic force from a distance.
A star will ultimately become a black hole when it collapses due to end of fuel.
<h3>Which star becomes a black hole?</h3>
When a star burns through the last of its fuel, the object may collapse, or fall into itself. For smaller stars which are about three times the sun's mass, the new core will become a white dwarf but when a larger star collapses, it turns into a black hole.
So we can can conclude that a star will ultimately become a black hole when it collapses due to end of fuel.
