Electromagnetic radiation can be specified by its wavelength ( ), its frequency ( ) or its period ( ). The period is the time it
1 answer:
Answer:
The relation between f,T,λ
f=
λ =
λ =
Explanation:
Let us consider,
wavelength as λ
frequency as f
time period as T
The <em>time period</em> is defined as time taken by the wave to complete one oscillation or number or seconds to complete one full oscillation.
The <em>frequency </em>is defined as number of oscillation done per second.
The <em>wavelength</em> is defined as distance between two successive crests or trough. in a wave.
<em>The frequency and time period are reciprocals. </em>
<em>The wavelength and frequency are reciprocals ie larger the wavelength shorter is the frequency</em>
The relation between frequency and time period is f =.
The relation between wavelength and frequency is λ =
where v is velocity of light.
The relation between wavelength and time period is λ =

By holding a positive charge and there are positive charges of equal magnitude 1 m to your north and 1 m to your east. Therefore, the direction of the force on the charge you are holding will be to the southwest.
Let I hold the charge , q at the centre of given co-ordinate system and two positive charge of equal magnitude Q are placed 1 m to my North and 1 m to my South .
now, both the charge are same nature e.g., positive . Let my charge is also positive (well, you can assume negative too , I am considering positive because it makes me easy to solve) then, both charge repel to my charge.
charge Q placed on east is repelling my charge q toward west . similarly charge Q placed on North is repelling my charge q toward south.
Now , use vector for solve it.
vector = vector Fe + vector Fn,
⇒ || =
⇒ Fe = Fs = KqQ/(1m)² = KqQ
⇒ = √{Fe² + Fs²} = √{(kqQ)²+(KqQ)²}
⇒ = √2KqQ
Hence, net force act on q {my charge } is √2KqQ and the direction of force is S - W (southwest )direction.

Answer:
Small sports car.
Explanation:
Lets take
mass of the small car = m
mass of the truck = M
As we know that when car collide with the massive truck then due to change in the moment of the car both car as well as truck will feel force.We also know that from Third law of Newton's ,it states that every action have it reaction with same magnitude but in the opposite direction.
Therefore
F = m a
a=Acceleration of the car
F= M a'
a'=Acceleration of the massive truck
Here given that M > m that is why a > a'
Therefore car will experiences more acceleration.
