Answer:
The non-relativistic kinetic energy of a proton is 
The relativistic kinetic energy of a proton is 
Explanation:
Given that,
Mass of proton 
Speed
We need to calculate the kinetic energy for non relativistic
Using formula of kinetic energy

Put the value into the formula


We need to calculate the kinetic energy for relativistic
Using formula of kinetic energy



Hence, The non-relativistic kinetic energy of a proton is 
The relativistic kinetic energy of a proton is 
Answer:

Explanation:
The textbooks say that the maximum range for projectile motion (with no air resistance) is 45 degrees.
Answer:
A blackbody, or Planckian radiator, is a cavity within a heated material from which heat cannot escape. No matter what the material, the walls of the cavity exhibit a characteristic spectral emission, which is a function of its temperature.
Example:
Emission from a blackbody is temperature dependent and at high temperature, a blackbody will emit a spectrum of photon energies that span the visible range, and therefore it will appear white. The Sun is an example of a high-temperature blackbody.
The frequency of the wave is 6800 Hz
<u>Explanation:</u>
Given:
Wave number, n = 20
Speed of light, v = 340 m/s
Frequency, f = ?
we know:
wave number = 

Therefore, the frequency of the wave is 6800 Hz
