<u>Answer:</u>

<em>27 is its atomic mass</em>

<u>Explanation:</u>

Isotope in chemistry refers to a similar variant of same chemical element where they only differ in number of neutrons <em>while the number of protons remains the same. </em>

Since the <em>aluminum isotope consists 13 protons and 14 neutrons, the mass number of the aluminum isotope </em>would be equal to the sum of number of protons and neutrons present.

<em>As there are 13 protons and 14 neutrons so the mass number will be equal to 27.</em>

Answer:

R: 27 u

ou 27g/mol

Explanation:

A massa atômica de um elemento é dada pela soma do número atômico (número de protons) com o número de neutrons. Assim:

A= 13+14 = 27

Find the equilibrant of two 10.0-N forces acting upon a body when the angle between the forces is 90° Solve graphically using a
bazaltina [42]

The equilibrant force of the two given forces is 14.14 N.

<h3 /><h3 /><h3>What is equilibrant force?</h3>
  • This is a single force that balances other given forces.

The given parameters:

  • First force, F₁ = 10 N
  • Second force, F₂ = 10 N
  • Angle between the forces, θ = 90⁰

The equilibrant force of the two given forces is calculated as follows;

F = \sqrt{F_1 ^2 + F_2 ^2} \\\\F = \sqrt{(10)^2 + (10)^2} \\\\F = 14.14 \ N

Thus, the equilibrant force of the two given forces is 14.14 N.

Gwar [14]
<h3><u>Answer;</u></h3>

the north end to the south end.

<h3><u>Explanation;</u></h3>
  • Magnetic field lines from a bar magnet form lines that are closed. The direction of magnetic field is taken to be outward from the North pole of the magnet and in to the South pole of the magnet.
  • A magnetic field refers to  the area surrounding a magnet where a force is exerted on certain objects. These lines are spread out of the north end of the magnet.
  • The magnetic field lines resemble a bubble.
