Answer: The number of electrons in an atom of zirconium are 40.

Explanation:

Electrons are one of the subatomic particles present in an atom.

Electrons in an atom is judged by the atomic number of the atom.

Atomic number = Number of protons = Number of electrons

Atomic number of Zirconium = 40

Number of electrons will be equal to 40

Electronic configuration of Zirconium (Z = 40): 1s^22s^22p^63s^23p^64s^23d^{10}4p^65d^24d^2

A high school physics student is sitting in a seat read-
Nataly_w [17]

The equilibrium condition allows finding the result for the force that the chair exerts on the student is:

  • The reaction force that the chair exerts on the student's support is equal to the student's weight.

Newton's second law gives the relationship between force, mass and acceleration of bodies, in the special case that the acceleration is is zero equilibrium condition.

            ∑ F = 0

Where F is the external force.

The free body diagram is a diagram of the forces on bodies without the details of the shape of the body, in the attached we can see a diagram of the forces.

Let's analyze the force on the chair.

            N_{chair} - W_{chair} - W_{student} = 0 \\ \\N_{chair} = W_{chair} + W_{student}

Let's analyze the forces on the student.

          N_{student} - W_{student} = 0  \\N_{student} = W _{student}

           

In conclusion using the equilibrium condition we can find the result for the force that the chair exerts on the student is:

  • The reaction force that the chair exerts on the student's support is equal to the student's weight.
