1 coulomb of electric charge is carried by 6.25 x 10^18 electrons
1 Ampere = 1 coulomb per second
10 A = 10 coulombs per second
(2.0 x 10^20 electrons) x (coul / 6.25 x 10^18 electrons) / (10 coul/sec) =
(2.0 x 10^20) / (6.25 x 10^18 x 10) sec = <em>3.2 seconds</em>

Explanation:
Answer:
The dog should walk 60 steps to the southeast to return to its starting point.
Explanation:
To solve the present mathematical problem, we must use the Pythagorean theorem. This establishes that in right triangles the sum of their squared legs is equal to the hypotenuse squared, that is:
A ^ 2 + B ^ 2 = X ^ 2
Thus, in the case, the calculation would be the following:
24 ^ 2 + 55 ^ 2 = X ^ 2
576 + 3,025 = X ^ 2
√3,601 = X
60 = X
Therefore, the dog should walk 60 steps to the southeast to return to its starting point.
Answer:
c) The concepts of quantitative and qualitative are not related at all.
Explanation:
Quantitative properties are those which can be compared by its magnitude only
so it is always in relative terms like we can compare them by which one is larger and which one is smaller
Qualitative terms are those which will compare the quality of two like which one is better in terms of given property
so here we can say that quantitative and qualitative terms is not comparable
hence correct answer will be
c) The concepts of quantitative and qualitative are not related at all.
