Answer:
1 mm^3 = 1.0 x 10^-9 m³
Hence;
5.23 x 10^-6 kg/mm^-3 = (5.23 x 10^-6 kg)/ 1x10^-9 m³
= 5230 kg/m³
Your pet must have current vaccinations that are required by the place (state, country, etc.) that it will be entering. Your pet would also need a health certificate that was done by a licensed veterinarian.
The function of concrete shielding in a nuclear reactor is: <u>to contain radiation.</u>
<u>Explanation</u>:
The reactor core in the nuclear reactor is placed in a steel pressure vessel. The steel vessel is then shielded by a thick layer of concrete. The concrete shielding is done to protect the workers from radiation.
The nuclear power station must be built on hard solid rock as the reactor is heavy in structure. The radiation emitted from the reactor may harm the human being. To avoid this, the concrete shield is made to prevent the emission of radiation.
C, all cells contain chloroplast, is not part of the cell theory.
Mass = 0.5 kg
H = 20m
G = 9.8 m/s^2
U (Potential energy) = M×g×h
= 0.5 × 9.8 × 20 = 98 J
