At what speed is a particle's kinetic energy twice its rest energy?
bezimeni [28]
The total energy of a particle is its rest energy plus the kinetic energy. Its formula is: Et= m^2/sqrt((1-v^2)/c^2))
The rest energy is equal to the product of mass and the square of light velocity: Er=mc^2.
When the kinetics energy is twice its rest energy this holds:
Et=Er
m^2/sqrt((1-v^2)/c^2))=<span>mc^2.
</span><span>sqrt((1-v^2)/c^2))=m/c^2
</span>=> v=sqrt(3/2)c

1. Our solar system was created by the gravitational collapse of the______.
Elden [556K]

Answer:

  1. Solar nebula
  2. Planetesimal
  3. Heavy bombardment
  4. Accretion
  5. Solar wind
  6. Condensation
  7. Frost line
  8. Radiometric dating

Explanation:

Solar nebula is a gaseous cloud and it have been considered that when it condensed, Sun and other planets are formed.

Planetesimal term is used for an object which is formed from rock, dust and some other materials.

When growth occurs due to gradual accumulation of layers then it is called Accretion.

A stream of charged particles (electrons and protons) having extreme energy and flowing outward from the Sun at speeds approximately 900 km/s and at a temperature of 1 million degrees is termed as Solar wind.

Radiometric dating is the name of technique that is used to calculate the age of the materials such as rocks or carbon.
