Answer:
Cosmic ray is not considered electromagnetic radiation.
Explanation:
Electromagnetic radiation refers to
- It is Radiation that has both electric and magnetic fields and travels in waves.
- Electromagnetic radiation can vary in strength from low energy to high energy.
X rays are the rays produced when a negatively charged electrode is heated by electricity and electrons are released, thereby producing energy. It is a type of radiation called EM waves.
Radio wave are wave from the portion of the electromagnetic spectrum at lower frequencies than microwaves. It is an EM wave.
Ultraviolet wave Invisible rays that are part of the energy that comes from the sun. It is an example of EM wave.
Cosmic ray is a high-speed particle either an atomic nucleus or an electron that travels through space.
Cosmic ray is not an electromagnetic wave.
Hence
Cosmic ray is not considered electromagnetic radiation

Solid elements are rigid elements. For example an element iron is in solid form. You can touch it and it’s hard.
Answer:In first case
Explanation:
When two People pull the spring, let the applied force by each person be 
and spring constant of spring be k
so Total force is 
total extension according to Hooke's law is
When they detach the spring and apply force in opposite direction then force on either side is F so net extension is
so in first case there will be more extension
Answer:
the peak wavelength when the temperature is 3200 K = 
Explanation:
Given that:
the temperature = 3200 K
By applying Wien's displacement law ,we have
T = 0.2898×10⁻² m.K
The peak wavelength of the emitted radiation at this temperature is given by
= 
=
Hence, the peak wavelength when the temperature is 3200 K =
