Answer:
ΔE / E = ΔV / V + Δd / d
Explanation:
The electric field and voltage are related by the expression
E = V / d
The uncertainty of the field is
ΔE / E = ΔV / V + Δd / d
We see that the uncertainty of the field must be added the uncertainty of the distance that in the measure of the different potential has no effect.
The only case in which the uncertainties are equal is if the distance measurement has no uncertainty, or the separation of very high
I go with D .
Explanation:
I go with D because neither if the ballons have the same thermal energy.
Answer:In primary succession, newly exposed or newly formed rock is colonized by living things for the first time. In secondary succession, an area previously occupied by living things is disturbed—disrupted—then recolonized following the disturbance.The first organisms to appear in areas of primary succession are often mosses or lichens. These organisms are known as pioneer species because they are the first species present; pioneer species must be hardy and strong, just like human pioneers.A heterotroph is an organism that eats other plants or animals for energy and nutrients. The term stems from the Greek words hetero for “other” and trophe for “nourishment.” Organisms are characterized into two broad categories based upon how they obtain their energy and nutrients: autotrophs and heterotrophs.
