D
Explanation:
<em>The correct answer would be in the axle of the wheels while you ride your bicycle.</em>
Options A, B, and C requires that the forces of friction is increased in order to have more control.
However, option D requires that there is a minimal frictional force in the axle of the wheels of a bicycle while riding so that a little effort would be required to keep the bicycle moving.
<u>The lesser the friction, the lower the effort that would be needed to keep the bicycle moving and vice versa.</u>
A Atom is the basic unit of each type of element
<h3><u>Answer;</u></h3>
<u> = 55.2 Coulombs </u>
<h3><u>Explanation</u>;</h3>
We can determine Charge using the formula
Q =It, where Q is the amount of charge in Coulombs, I is the current in amperes and t is the time in seconds.
I = 0.92 amperes, t = 1 minute or 60 seconds
Charge = 0.92 × 60
<u> = 55.2 Coulombs </u>
