b) The speed of the block is determined by using the Principle of Energy Conservation:




The radius of the circular loop is:



Homeostasis is the tendency toward a relatively stable equilibrium between interdependent elements, especially as maintained by physiological processes.
B. Fusion requires very high pressure and temperature.
Explanation:
Nuclear fusion is the combination of atomic nuclei into larger ones with the release of a large amount of energy.
Nuclear fission is the decay process in which a heavy nuclide is bombarded with with neutrons.
- Both processes release a huge amount of energy.
- But fusion produces far more energy.
- The reason why nuclear fusion is not in use is because of the high pressure and temperature needed start it.
- The activation energy is high and the energy barrier is very great.
- Only the core of the sun naturally favors fusion

Answer:
1/3 m/s
Explanation:
Because the graph goes from 3 to 8 on the Y axis we know that each line is 0.5 and on the X axis each line is 1, Then, the slope , or velocity, is 1/3
see? This graph is kinda set up to throw you.
Is there a 1/3 option for this ??
