The correct option is B.
In the ecosystem, energy flows from one trophic level to the other. The first trophic level is that of the producers which use the energy of the sun to produce their own food. Out of the energy obtained from the sun by the producers only about 3% of it is converted into food products. The second trophic level is made up of the herbivores and the omnivores which eat the plant. Only about 10% of the energy from the plant is transferred to the animals in the second trophic level. These second trophic level animals will also transfer about 10% of the energy they obtain to the animals in the third trophic level when they are eaten. Thus, it can be seen that the energy that is transferred in the ecosystem is gradually reducing from one trophic level to another.

The nucleus of "Lead-208", 208 82 Pb, has 82 protons within a sphere of radius 6.34×10-15 m. Each electric charge has a value of
jarptica [38.1K]

Answer:

2.94 × 10²⁰ N/C

Explanation:

Given that:  

The nucleus of "Lead-208 has 82 protons,

with a radius (r) 6.34×10-15 m, &

each electric charge has a value of 1.60218 × 10^-19 C

∴ The formula for calculating an electrical field at the surface of the nucleus is:

 E=\frac{k*q}{r^2}  

Substituting our values into the equation above, we have;

 E = \frac{8.98755*10^8*82(1.60218*10^{-19C)}}{(6.34*10^{-15}_m)^2}

E = 2.93870499×10²⁰ N/C

E ≅ 2.94 × 10²⁰ N/C
