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
Answer:
B. Habitat destruction

What is the number one cause of biodiversity loss? 1. Habitat destruction. Habitat destruction is a major cause of biodiversity loss.
Answer:
What is a good example of a response-based definition of stress?
Bruce experiences stress because his heart rate increased when he noticed Jack had a knife.
Explanation:
Stress can have many different causes. In this case, it is produced by seeing danger in Jack by having a knife. His heart rate increases because this is a common response in stress, which would enable people to scape. It is important to control stress lebels.
A stressor is distinguished as a threat. If someone anticipates that it could lead to some kind of harm, loss, or other negative consequence. However, if you see the positive side and believe that it carries the potential for gain or personal growth, it would be appraised as a Challenge.
Answer:
Explanation:
Yes, for a couple of reasons.
1. Carbon connects easily with other carbons.
2. Carbon forms chemical that can change and connect with other carbons even in biology or especially in Biology. If you take a brown seen and plant it where it can get water and soil nutrients, to will come up as a green plant. Think about the chemistry that goes into that. Not only that, but there are mechanisms that tell the upper part of the plant that the roots can't supply any more growth. Isn't that something? All made from Carbon.
3. The human body is a mass of Carbon based chemicals and all cells there can have different functions. Amazing isn't it? I'm a fan of the diversity of our planet and its growth.
Answer:
pericardium
Explanation:
A double-walled membrane, the pericardium, separates the right and left chambers, preventing oxygen-rich blood from mixing up with the one without oxygen. So, the heart functions go smoothly. Deoxygenated blood enters the right atrium.
