Answer:
Explanation:
Given that,
Charge, Q = 2.1 C
The radius of sphere, r = 1.3 cm = 0.013 m
We need to find the charge per unit volume for this situation. It can be calculated a follows:
So, the charge per unit volume is 
.
Answer:
Because there is less energy at higher trophic levels
Explanation:
- In a food chain that shows the feeding levels of organisms in an ecosystem, energy decreases as you move from the lowest trophic level to the highest trophic level.
- The lowest trophic level consists of producers which have the highest energy as they trap energy directly from the sunlight.
- The energy is lost from one trophic level to the next up to the highest trophic level which has the lowest energy.
- Therefore, organisms at the highest trophic level are fewer in number but large in size.
Newton was given the title "scientist" when he was given the Merit Badge at the age of 15. He continued to work in the field of science, and was considered a scientist until his death at the age of 84. That is a total of 69 years of work. Hope this helps!
Answer:
300 J
Explanation:
Work = (Force)*(distance) = 600 N ∗ 0.5 m = 300 J
