Letter na that would be the answer
Answer:
Friction, normal force, and weight
Explanation:
If the book slows down, it means that there must be friction acting in the opposite direction of the direction the book is moving in.
Weight is caused by the gravitational pull of the Earth on the book, and normal force is the table pushing the book up because the book is pushing down on the table (3rd law.)
Note that weight and normal force is not the 3rd law action-reaction pair. The pair is the force of the book on the table and the force of the table on the book.
Answer:
no material that were once part of living things
Answer:
Newton
Explanation:
The earth attracts every body towards its centre. The force with which the earth attracts any body towards its centre, is called its weight.
It is a vector quantity.
It always acts towards the centre of earth.
The SI unit of Newton.
Answer:
The arrow rise 44.64 m high assuming air friction is negligible
Explanation:
According to the law of conservation of energy
Kinetic energy = Potential energy at highest
----1
We know that F=kx
So,
Substitute the value in 1
Hence the arrow rise 44.64 m high assuming air friction is negligible
