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:
Substituting our values into the equation above, we have;
E = 
E = 2.93870499×10²⁰ N/C
E ≅ 2.94 × 10²⁰ N/C
So you know what is what and where it goes
A volcanologist is a geologist who studies the process involved in the formation of a volcano. He also studies the eruptive nature of the volcano along with their current and historic eruptions.
The tasks done by a volcanologist do to study volcanoes are =
1. use autoclaves to imitate the interior of a volcano
2. simulate volcanic explosions with computer programs
3. study lava samples
4. listen to the sounds of the interior of a volcano
Answer:
The answer is C. BPG aids oxygen delivery to tissues by increasing the affinity of myoglobin for oxygen
Explanation:
The 2,3-bisphosphoglycerate (BPG) which can also be referred to as the 2,3 - di phosphoglycerate , is being produced by the red cells and has the ability to deoxygenate hemoglobin. This is because , his accumulation results to a decrease in the affinity for oxygen, this means that , it will convert hemoglobin to a low oxygen affinity state.
In this case, comparing the options given, it will be concluded that, 2,3 -biphosphoglycerate {BPG} does not aids the delivery of oxygen to tissues, but decreases the affinity of oxygen, which deoxygenate hemoglobin, and causes the concentration of the carbon dioxide to increase.
NITROGEN FIXING BACTERIA processes nitrogen in the atmosphere and make it available to other living forms in a usable form. Nitrogen fixing bacteria are micro organisms which are capable of transforming atmospheric nitrogen into fixed nitrogen. An example of a nitrogen fixing bacteria are bacteria in the genera azotobacter.
