Florence Griffith-Joyner recorded a time 10.61 seconds (wind reading +1.2) in the final at the 1988 U.S. Olympic Trials the wind reading for this race is not in doubt, and the performance should be the official IAAF women's 100-m world record
Answer:
due to the effect of gravity begins thermonuclear fusion processes, in these processes energy is released in the form of electromagnetic radiation
Explanation:
The Sun is a star of great size, which due to the effect of gravity begins thermonuclear fusion processes, in these processes energy is released in the form of electromagnetic radiation.
This radiation crosses the different layers of the Sun and escapes from it in the form of light that is emitted throughout the radiation spectrum, due to the temperature reached by the Sun about 5500K the most likely radiation is around 5500 nm corresponding to the green- yellow of the visible spectrum, but the entire spectrum is emitted with different intensity according to Stefan's law
In quantum mechanics this spectrum can also be analyzed as the emission of particles called photons, where each one is characterized by an energy and has a moment equal to zero, the energy of these photons is related to their frequency by the Planck equation
E = h f
I think the correct answer is D: Potential Energy.
Radioactivity is a nuclear phenomenon. It is the process of spontaneous emission of α (alpha particles) or β (beta particles) and γ (gamma particles ) radiations from the nucleus of atoms during their decay.
- Uranium and radium are the two radioactive substances.

<h2>The distance covered by man is 6.4 m</h2>
Explanation:
In the interference of two waves , these will fall upon each other .
It will make nodes and anti-nodes in between . There will be one node in between two anti-nodes and will be one anti-node between two nodes .
The distance between two nodes is λ/2 and distance between two anti-nodes is also λ/2
Thus if the man is at constructive interference , so to move at destructive interference , it has to cover a distance equal to λ/4
Here λ = velocity/frequency = 344/632 = 18.4 m
Thus the distance he will cover = 18.4/4 = 4.6 m
