Electromagnetic radiation consists of discrete packets of kinetic energy called Photons, which are characterized by a certain wavelength and energy level.
<h3>What are
photons? </h3>
The representation by a particle of a quantum of light or any other electromagnetic radiation is called photons. The energy is proportional to the frequency of radiation however it has zero mass. It travels at a constant speed. It is a carrier of energy. When the sun changes the particles into both light and heat, it is a photon. They don’t carry any electrical charge. They are like electric fields traveling through space as shown by Maxwell in his theory. They can be easily created and destroyed. They are also called light quantum.

Answer:
The mass is 
Explanation:
Generally from Newton law for the first block
=> 
For the second block the force is 
and the acceleration is 
So from Newton law
=> 
substituting for a
=> 
=>
Answer
225 meters.
Explanation:
x=x0+30t-(1/2)(1.5)t^2
x=0+30(10)-(1/2)(1.5)(10)^2
x=300-75
x=225
Conduction, since the iron is in direct contact with the clothes.
