Answer:
The energy carried by an electromagnetic wave is proportional to the frequency of the wave. The wavelength and frequency of the wave are connected via the speed of light: Electromagnetic waves are split into different categories based on their frequency (or, equivalently, on their wavelength).
Explanation:
Answer with explanation:
The given vectors in are reduced to their componednt form as shown
For vector A it can be written as
Similarly vector B can be written as
Hence The sum and difference is calculated as
The direction is given by
with positive x axis.
Similarly
The direction is given by
with positive x axis.
Answer:
one at the edge
Explanation:
The relation between the linear velocity and the angular velocity is given by
v = r x ω
Where, v be the linear velocity, ω be the angular velocity and r be the radius of the circular path.
As the angular velocity is constant, thus, the linear velocity depends on the radius of circular path.
So, the horse which is near to the edge has maximum radius of circular path in which it is rotating. So, the horse which is at the edge of the merry go round has maximum linear speed.
Conduction, Convection, and in some cases, Radiation.
