Answer:
Explanation:
Ions are substances the have lost or gained a certain amount of electrons. This makes them either positively or negatively charged.
They are charged particles.
- Every atom is made up of protons, neutrons and electrons.
- They are the three fundamental particles in any atom
- The protons and neutrons are located in the central part called the nucleus of an atom. It is a simple tiny space.
- Protons are positively charged particles. Neutrons do not carry any charges. Therefore, the nucleus is negatively charged.
- Electrons are negatively charged particles. They occupy the bulk volume of an atom.
Every atom is neutral and the number of protons and electrons are the same. The equal number of protons and electrons balances to attain neutrality of an atom.
Electrons are very easy to lose since they occupy the outermost shell.
- When an atom loses an electron, the number of protons is more than electrons. Therefore, it becomes positively charged. Hence, its is called an anion.
- An atom can also gain an electron, the electron number will be more than the protons. They then become negatively charged and are called cation.
Cations and ions are substances that are produced to attain a special type of bonding called electrovalent bonding.
Oppositely charged substances attracts one another.
Answer:
The answer to your question is: 5 N to the west or to the left
Explanation:
Both forces go to the left, so the net force will be the sum of them.
Net force = 3 N + 2 N
Net force = 5 N
to the left, because the arrows signal to that direction
Answer : The electric current of a circuit is, 2.8 A.
Explanation :
Using Ohm's law :
Or,
where,
R = resistance of a circuit = 28 Ω
V = voltage of circuit = 76 volts = 76 V
I = current flowing in a circuit = ?
Now put all the given values in the above formula, we get :
Therefore, the electric current of a circuit is, 2.8 A
We know that the centripetal acceleration is zero, since the summation of forces is the mass times the acceleration in the x- component.
