Max Weber believed that the study of society should involve social activism.
The reason why iron oxide has more mass than the iron is because Iron oxide has oxygen atoms, and pure iron does not.
When iron rusts and forms iron oxide, the iron oxide has more mass than the iron. Which statement correctly explains this
observation?
(A)Iron oxide has oxygen atoms, and pure iron does not.
(B)The oxygen atoms in iron oxide have more mass than the iron atoms in pure iron.
(C)The iron atoms in iron oxide have more mass than pure iron.
(D)There are more iron atoms in iron oxide than in pure iron.
When a chemical reaction takes place, other atoms are combined with pure elements to form compounds. This addition of another atom (oxygen) after reaction makes iron oxide formed heavier than pure iron.
Iron oxide is a chemical substance formed when pure iron rusts. The formation of iron oxide is a chemical reaction.
Hence, the correct answer to the question is; the iron is heavier because Iron oxide has oxygen atoms, and pure iron does not.

The watts that are consumed in a circuit that is having power factor of 0.2 and input is 100V at 4 ampheres is 80 watts.
Given that power factor is 0.2, input is 100V and electricity current be 4 amperes.
We are required to find the number of watts that are consumed in circuit.
An electric current is basically a stream of charged particles, such as electrons or ions, moving through an electrical conductor or space.
Power factor is basically the ratio of working power, measured in kilowatts , to apparent power, measured in kilovolt amperes.
Number of watts that are consumed will be=100*0.2*4
=80 watts
Hence the watts that are consumed in a circuit that is having power factor of 0.2 and input is 100V at 4 ampheres is 80 watts.
