Refraction and reflection both shows the wave property of light and the difference between them is that during reflection the medium of light will not change while in refraction the light will change its medium
so in reflection of light we use that angle of incidence = angle of reflections with respect to normal
While in refraction we use Snell's law
Diffraction of light is the phenomenon of light in which light will bend at the corners and enter into the region of dark
While absorption is the phenomenon of energy absorption when light incident on any medium or surface
Answer:
<u>Gravitational Force</u> is a force that attracks two objects with mass. For example, you are being pulled onto this planet, and that's why when you jump upwards, you fall back down quickly. A fun fact is that every object, even the entire universe, are pulling all on each other, including you!

As the distance between two magnets increases, the force between them <em>decreases</em>.
If the force increased along with distance, then the magnet in your hand would reach out
and grab every magnet in Australia or on Mars and pull it toward you.
Answer:
0.0360531138247 V/m
Explanation:
= Resistivity of gold = (General value)
I = Current = 940 mA
d = Diameter = 0.9 mm
A = Area =
E = Electric field
Resistivity is given by
The electric field in the wire is 0.0360531138247 V/m
Answer:
option is option d)
Explanation:
the correct option is option d)
the characteristic of thunderstorm can be seen by the following scenario
in thunderstorm there is lot of movement of air the lighter i.e.warmer air moves up and the colder air moves down creating the condition of thunderstorm.
heavy rain , strong wind , potentially large hail stones is the situation of the thunderstorm.
during thunderstorm there is rain and snow at intermediate.
hence only option left is option d.
