A neutron and a large nucleus.

In normal fission reactors, the fuel used to start the nuclear fission is Uranium-235. 
Generally, fuel rods enriched with uranium-235 are used to start the fission. When a nucleus of uranium-235 absorbs a neutron, it becomes unstable and then it breaks apart, producing two smaller nuclei, several neutrons and energy. The additional neutrons produced in the reaction are then absorbed by other nuclei of uranium-235, triggering other fission reactions, and so on.

All objects in the universe radiate some form of energy.<br> a. True<br> b. False
Harrizon [31]

That's true.  The only way to stop an object from radiating energy
is to cool it to absolute zero.  Since the temperature of space is
roughly 3 degrees above absolute zero, the atoms or molecules
of every object have some kinetic energy, and the object radiates
some heat. 

Of course it also absorbs heat at the same time, mostly from the
huge number of stars shining on it.

A 6.25 L tank holds helium gas at a pressure of 1759 psi. A second 6.25 L tank holds oxygen at a pressure of 467.7 psi. The two
rodikova [14]

Answer:

P=1113.35 psi

Explanation:

For tank 1

V₁= 6.25 L

P₁=1759 psi

For tank 2

V₂=6.25 L

P₂=467.7 psi

Lets take final pressure is P

The final volume  V= 6.25 + 6.25 L = 12.5 L

P V = V₂P₂+V₁P₁

Now by putting the values

P V = V₂P₂+V₁P₁

P x 12.5 = 6.25 x 467.7+6.25 x 1759

P=1113.35 psi

So the final volume of the system will be 1113.35 psi.

While for the Topography,

Geology and Soils Minor, localized

impacts within project

footprint where observed and there was a potential major impacts within the footprint of the lake.

Surface Water Hydrology, it has minor short term adverse impact and a major, long term adverse impacts to Rough River hydrology between the dam and new outlet works Increased risk of major, long

term changes to hydrology upstream of dam. For the Groundwater there was no significant adverse impact. While the Vegetation had minor adverse impact Minor adverse impact.

Aquatic Resources had long-term beneficial impact.
