Answer:
Friction, normal force, and weight
Explanation:
If the book slows down, it means that there must be friction acting in the opposite direction of the direction the book is moving in.
Weight is caused by the gravitational pull of the Earth on the book, and normal force is the table pushing the book up because the book is pushing down on the table (3rd law.)
Note that weight and normal force is not the 3rd law action-reaction pair. The pair is the force of the book on the table and the force of the table on the book.
Answer: It opposes the flow of electrons.
Explanation: just did the quiz on
An atom is made up of three different particles, which are proton, neutron and electron. The proton and the neutron are located in the nucleus of the atom and they make up mass of the atom. The electron orbit around the nucleus. The proton is positively charged while the electron is negatively charged, thus, for the atom to remain neutral, the number of proton and electron in an atom must be equal. The neutron has no charge.
The atomic mass of an element = number of proton + number of neutron
Atomic mass of magnesium= 24
Number of proton = 12
Therefore, number of neutron = 24 - 12 = 12.
Thus, the number of neutron = 12.
We need to find the time it takes an electron to move in the given circuit.
The time taken for electrons to reach the starting motor from the battery is 60.65 minutes.
I = Current = 134 A
= Avogadro's number = 
A = Area = 
L = Length = 92.2 cm
= Density of copper = 
M = Molar mass of copper = 63.5 g/mol
= Number of valence electrons of copper = 1
e = Charge of electron = 
Number of charge carriers per unit volume is given by

Time taken is given by

The time taken for electrons to reach the starting motor from the battery is 60.65 minutes.

Answer:
True
Explanation:
Whenever electrons are transferred between objects, neutral matter becomes charged. For example, when atoms lose or gain electrons they become charged particles called ions. Three ways electrons can be transferred are conduction, friction, and polarization. In each case, the total charge remains the same.
I tried, hope this helps :)
