  1. 3. The SI unit for magnetic flux
  2. 5. The effect that results in the emission of electrons from a material caused by electromagnetic radiation
  3. 7. The interval of time between successive occurrences of the same state in an oscillatory or cyclic phenomenon
  4. 8. The quantum of light and all other forms of electromagnetic radiation, and the force carrier for the electromagnetic force.
  5. 14. A proton contains two up quarks and one _____ quark
  6. 15. The force that keeps a body moving with a uniform speed along a circular path and is directed along the radius towards the centre
  7. 16. The component of a contact force that is perpendicular to the surface that an object contacts.
  8. 17. This gauge boson mediates the strong interaction between quarks.
  9. 18. The unit for magnetic flux density, also called magnetic field strength
  10. 19. The radiation has a specific spectrum and intensity that depends only on the temperature of the body.

  1. 1. A non-accelerating frame of reference
  2. 2. The type of field that relates to the region of space surrounding a body in which another body experiences a force of gravitational attraction
  3. 4. Kepler's law that state that the square of the orbital periods of the planets are directly proportion to the cubes of the semi-major axes of their orbits.
  4. 6. The type of radiation including visible light, radio waves, in which electric and magnetic fields vary simultaneously

  7. 11. The wavelength associated with the wave-like nature of elementary particles such as electrons
  8. 12. This law states the direction of the electric current induced in a conductor by a changing magnetic field
  9. 13. The concept whether two spatially separated events occur at the same time – is not absolute, but depends on the observer's reference frame.
