The uncertainty in the time of the runner to complete the distance is 11.5 s ± 0.1955 s

The given parameters;

length of the track, d = 100 m

time to complete the track, t = 11.5 s

the uncertainty, = 1.7%

The uncertainty in the time of the runner to complete the distance is calculated as;

the uncertainty = ± (0.017 x 11.5)

the uncertainty = ± 0.1955 s

Thus, the uncertainty in the time of the runner to complete the distance is 11.5 s ± 0.1955 s

Georgia [21]

nuclear energy

Explanation:

The sunlight that reaches earth is generated by a transformation of nuclear energy. Radiant energy is a from of energy that reaches the earth from nuclear reactions in the core of the sun.

  • In this process, light nuclei combines to form larger ones through the process of nuclear fusion.
  • This process does not conserve energy and mass is converted to energy.
  • The nuclear reaction produces huge energy that goes into the solar system space and lights it up.
  • Therefore, it is a transformation of nuclear energy into radiant energy.
  • The radiant energy is made up of electromagnetic radiations.
