The sequence of types of electromagnetic radiation is arranged from that with the least to the most energetic photons will be visible light , ultraviolet, x-rays, gamma rays.
<h3>What is electromagnetic radiation?</h3>
Electromagnetic radiation is a type of energy that is transmitted in incident photons as both magnetic and electric waves.
Electromagnetic radiation has a spectrum with varying wavelengths and frequencies, which gives it different properties.
Electromagnetic radiation is a type of energy that travels in packets of energy called photons as both electrical and magnetic waves.
Wave-particle duality is the name given to this phenomenon. This is a notion that defines how a wave behaves whether it behaves like particles, waves, or both particles and waves.
Hence the sequence of types of electromagnetic radiation is arranged from that with the least to the most energetic photons will be visible light , ultraviolet, x-rays, gamma rays.

Answer:
Decrease the number of gas particles, increase the object's area, and reduce the temperature of the gas
Explanation:
<u>TEMPERATURE</u>:
Decreasing the temperature will slow down the molecules. Hence, less no. of collisions will take place between walls of object and molecules. This will result in decrease of pressure.
Therefore, the pressure of a gas can be decreased by increasing its temperature.
<u>NUMBER OF GAS PARTICLES</u>:
Decreasing the number of particles will result in less no. of collisions, hence decreasing the pressure.
Therefore, the pressure of a gas can be decreased by decreasing its no. of molecules or no. of particles.
<u>AREA OF OBJECT:</u>
The pressure is given by the formula:
where,
A = Area of Object
Therefore, the pressure of a gas can be decreased by increasing area of object.
So, the correct option is:
<u>Decrease the number of gas particles, increase the object's area, and reduce the temperature of the gas</u>
Answer:
The required angular speed the neutron star is 10992.32 rad/s
Explanation:
Given the data in the question;
mass of the sun M = 1.99 × 10³⁰ kg
Mass of the neutron star
M = 2( M )
M = 2( 1.99 × 10³⁰ kg )
M = ( 3.98 × 10³⁰ kg )
Radius of neutron star R = 13.0 km = 13 × 10³ m
Now, let mass of a small object on the neutron star be m
angular speed be ω.
During rotational motion, the gravitational force on the object supplies the necessary centripetal force.
GmM = / R² = mRω²
ω² = GM = / R³
ω = √(GM = / R³)
we know that gravitational G = 6.67 × 10⁻¹¹ Nm²/kg²
we substitute
ω = √( ( 6.67 × 10⁻¹¹ )( 3.98 × 10³⁰ ) ) / (13 × 10³ )³)
ω = √( 2.65466 × 10²⁰ / 2.197 × 10¹²
ω = √ 120831133.3636777
ω = 10992.32 rad/s
Therefore, The required angular speed the neutron star is 10992.32 rad/s
That would be false
