First:
d = 100 m
t = 200 sec
v = 100/200 = 0.5 m/s
Displacement is zero since he returned to his start point.
t2 = d/v2 = 100/2 = 50 sec
total time = 50 + 200 + 500 = 750 sec
73.5 million million million metric tons. or 7.3477 x 10^22 kilograms
When 2 waves interefere (or collide with eachother), it usually affects the crest of the wave. If both waves collide with both crests, it will create an amplified crest, and the waves will pass through eachother afterwards. If a trough of a wave meets a crest, it will cause the crest to be lowered shortly before both continue on.
The types of fusion that occurs in stars are:
- proton-proton fusion - stars with temperatures less than 15 million Kelvin and masses of 0.08 solar mass or more.
- carbon cycle fusion - occurs in stars with temperatures of 15 million Kelvin or more and masses of 4.0 solar mass or more
- helium fusion - occurs in stars with temperatures of 100 million Kelvin or more and masses of 0.5 solar mass or more
<h3>What is a nuclear fusion reaction?</h3>
A nuclear fusion is reaction in which nucleus of small atoms combine together to produces atoms of larger nucleus.
The types of nuclear fusion that can occur in a star include;
- Proton-proton fusion - occur in stars with core temperatures less than 15 million Kelvin and masses of 0.08 solar mass or more.
- Carbon cycle fusion occurs in stars with core temperatures greater than 15 million Kelvin having masses of 4.0 solar mass or more.
- Helium fusion - occurs in stars with core temperatures greater than 100 million Kelvin and masses of 0.5 solar mass or more
In conclusion, the types of fusion that occur in stars are proton-proton fusion, carbon cycle fusion and helium fusion.
