Answer:
The hummingbird travels the total distance is 10 m
Explanation:
Given that,
A hummingbird flies forward and backward.
According to figure,
We know that,
The total distance is equal to the sum of all distance.
Forward direction is positive and backward direction is negative.
We need to calculate the hummingbird travels the total distance
Using figure,

Put the value into the formula


Hence, The hummingbird travels the total distance is 10 m.
Answer:
The electrical potential energy is 0.027 Joules.
Explanation:
The values from the question are
charge (q) = 
Electric Field strength (E) = 
Distance from source (d) = 0.030 m
Now the formula for the electrical potential energy (U) is given by

So now insert the values to find the answer

On further solving

Answer:
Rutherford and atomic model are correctly matched.
A compound is a substance that consists of two or more elements, which is chemically combined, meaning that it could only be split by chemical means.
Examples:-
- NaCl is salt, chemically combined of Sodium and Chloride.
- H2O is water, chemically combined of Hydrogen and oxygen.
