Hey
Your answer is the one on the bottom
Newton's first law states that objects in motion will remain in motion (unless acted on by an external force) and that objects at rest will remain at rest.
On earth, if you throw a ball it will hit the ground and the friction between the grass and ball will slow it down. If the ground was frictionless then it would keep going forever.

In 2006, the International Astronomical Union created a new category of object in the solar system. The first object to be listed in that category was Pluto, and several more have been discovered and included since then.
The category is "Dwarf Planet" .
Answer: They both produce new cells, and start both with a single parent cell for similarities. For differences, Meiosis has only 8 stages in total, while mitosis is 4 stages in total. And for the Meiosis, it produces 4 haploid cells, and mitosis, only produces 2 haploid cells. These are the similarities and differences.
Hope this helped!
Answer:
Explanation:
Given
Sphere of Radius R
Suppose mass of block is m
At any instant \theta Normal reaction(N) and weight(mg) is acting such that
, where v is velocity of block at any angle \theta
When block is just about to leave then N=0
therefore
-------------------1
Also by conserving Energy we get
Potential Energy=kinetic Energy of block
here h=vertical distance traveled by block
From diagram
-----------------2
From 1 and 2
Thus from this value of h is
Explanation:
Iron has tiny magnetic domains inside it. Each domain acts like a tiny magnet with its own magnetic field. These domains are randomly distributed thus resulting in zero magnetic field and iron doesn't behave like a magnet.
When a copper wire is wound around the nail and current is passed through the coil, magnetic field is generated. This magnetic field penetrates through the nail. Due to this the magnetic domains of the nail align in the same direction thus having a net magnetic field. The nail behaves like a magnet till the time current flows through the coil.
