Answer:
There are four categories of byproduct material: Radioactive material that results from the fissioning, or splitting apart, of enriched uranium or plutonium in nuclear reactors. Examples include cobalt-60, cesium-137 and iridium-192. Tailings or waste produced by processing uranium or thorium from ore.
In 1869, just five years after John Newlands put forward his law of octaves, a Russian chemist called Dmitri Mendeleev published a periodic table. Mendeleev also arranged the elements known at the time in order of relative atomic mass, but he did some other things that made his table much more successful.
i hope this helps in some way!

Answer:
Initial Speed ____4m/s. Final Speed ______6m/s. Time ______5 seconds . Acceleration =________0.4m/s²
Explanation:
The acceleration is the rate of change of velocity during time t .
acceleration = Final velocity- Initial velocity/ Time
= Vf- Vi/ t
a = Δv/ Δt
= 6m/s- 4m/s/ 5s
= 2m/s/ 5s
= 0.4m/s²
It can also be defined as the difference of the initial and final velocity ( velocities measured in meters per second) during the given time t measured in seconds .The SI unit of acceleration is meter per second squared.
If the velocities are not measured in meters per second or time is not measured in seconds then the units are changed accordingly.
