Which ion in the ground state has the same electron configuration as an atom of neon in the ground state.

Answers

Answer 1

Na+ ion in the ground state has the same electron configuration as an atom of neon in the ground state.

The electronic configuration has been defined as the electron address in a atom. The electronic configuration has been based on the quantum rule for the filling of the electrons.

Neon is the tenth element with a total of 10 electrons. In writing the electron configuration for neon the first two electrons will go in the 2p orbital. Since 1s can only hold two electrons for Ne go in the 2s orbital. The remaining six electrons will go in the 2p orbital. Therefore, the Ne electron configuration 1s22s22p6.

Ne (atomic number=10) have 2,8 electron configurations. Here the atomic number of Na is 11. The configuration of Na is 2,8,1. Atomic number of Na+ is 10 and it has an electron configuration of 2,8 which is similar to Ne. Na+ ion is a positively charged particles, because they are missing one electron.

Answers

Answer:

c) It gets positively charged

Explanation:

If an electrically neutral body is loaded with protons so it gets positively charged because proton has positive charge. When the protons is added to the neutral body, it can't remain neutral because the quantity of positive charges increases in the nucleus and it gets positively charged while on the other hand, the atom from which protons are taken will acquire negative charge due to presence of more number of electrons and we know that electrons has negative charge.

Select all that apply…

A - motion of the source

B - the type of wave

C - original frequency of the source

D - motion of the observer

E - type of medium the wave is in

Answers

Answer:

the type of wave

Explanation:

Description: Doppler Effect works on both light and sound objects. For instance, when a sound object moves towards you, the frequency of the sound waves increases, leading to a higher pitch. Conversely, if it moves away from you, the frequency of the sound waves decreases and the pitch comes down.

A wave has a frequency of 60 Hz and a wavelength of 1.7 meters. What is the speed of this wave? equation, substitution

Answers

Answer:

v = 102 m/s

Explanation:

Given that,

The frequency of a wave, f = 60 Hz

Wavelength = 1.7 m

We need to find the speed of this wave. The formula for the speed of a wave is given by

[tex]v=f\lambda[/tex]

Substitute all the values,

[tex]v=60\times 1.7\\\\v=102\ m/s[/tex]

So, the speed of the wave is equal to 102 m/s.

A student of mass 45kg, who is undergoing National Service training, takes 6s to climb a flight of stairs that had 36 steps. If each step is 16cm high, what is the power of the student?

Answers

Answer:

Approximately [tex]4.2 \times 10^{2}\; \rm W[/tex] on average in the vertical direction (assuming that [tex]g = 9.8\; \rm N \cdot kg^{-1}[/tex].)

Explanation:

Vertical displacement of this student in [tex]6\; \rm s[/tex]: [tex]36 \times 16\; \rm cm = 36 \times (0.16\; \rm m) = 5.76\; \rm m[/tex].

Average vertical velocity of this student: [tex]v = \displaystyle \frac{5.76\; \rm m}{6\; \rm s} = 0.96\; \rm m \cdot s^{-1}[/tex].

The average vertical force that this student exerts on the ground would be equal to the weight of this student:

[tex]F = W = m \cdot g = 45\; \rm kg \times 9.8\; \rm N \cdot kg^{-1} = 441\; \rm N[/tex].

The average power of this student in the vertical direction is equal to the product of the force and velocity of this student in that direction:

[tex]P = F \cdot v = 441\; \rm N \times 0.96\; \rm m \cdot s^{-1} \approx 4.2\times 10^{2}\; \rm W[/tex].

Air from a metal can is removed so the pressure in the can decreases to 70000Pa, the can is then sealed. The pressure from outside the can is atmospheric pressure which is 100kPa. The area of one side of the can is 1.5m2, find the resultant force on this side of the can.

Answers

Answer:

F = 45 KN = 45000 N

Explanation:

Considering the downward direction as the positive direction:

[tex]P = P_1 - P_2[/tex]

where,

P = Resultant Pressure = ?

P₁ = Atmospheric Pressure = 100 KPa

P₂ = Pressure inside the can = 70000 Pa = 70 KPa

Therefore,

[tex]P = 100\ KPa - 70\ KPa\\P = 30\ KPa[/tex]

Now the resultant force will be given as:

[tex]F = PA[/tex]

where,

F = resultant force = ?

A = Area of side of can = 1.5 m²

Therefore,

[tex]F = (30\ KPa)(1.5\ m^2)\\[/tex]

F = 45 KN

Two resistors, 2.50 Ω and 4.95 Ω, are wired in series to a 12.00 V battery. What is the equivalent resistance of the circuit?

Answers

Answer:

7.45 Ω

Explanation:

From the question given above, the following data were obtained:

Resistor 1 (R₁) = 2.50 Ω

Resistor 2 (R₂) = 4.95 Ω

Voltage (V) = 12 V

Equivalent Resistance (Rₑq) =?

Since the resistors are in series arrangement, the equivalent resistance can be obtained as follow:

Rₑq = R₁ + R₂

Rₑq = 2.5 + 4.95

Rₑq = 7.45 Ω

Therefore, the equivalent resistance is 7.45 Ω

The energy of a single photon at the transmitted frequency is

A)3.55 × 10^(-28)J/photon

What is the energy of a single photon?

Energy of photon can be rewritten as

E=hv,

Where, h is planck's constant  

λ is the wavelength of photon  

Where f is the frequency of photon  

Thus, the energy of a single photon at the transmitted frequency obtained by using the formula, Energy (E) is equal to Planck's constant (h) times the frequency.

E=6.63×10^(-34)× 535×10^3

E =3.55 × 10^(-28) (J)

A young boy swings a yo-yo horizontally above his head so that the yo-yo has a centripetal acceleration of 200 m/s^2. If the yo-up’s string is 0.33 m long, what is the yo-up’s tangential speed?

Answers

Answer:

v = 8.12 m/s

Explanation:

The centripetal acceleration of the yo-yo is given by the following formula:

[tex]a_c = \frac{v^2}{r}\\\\v^2 = a_cr\\v = \sqrt{a_cr}[/tex]

where,

v = tangential speed = ?

ac = centripetal acceleration = 200 m/s²

r = radius = length of string = 0.33 m

Therefore, using the given values in the formula, we get:

[tex]v = \sqrt{(200\ m/^2)(0.33\ m)}[/tex]

v = 8.12 m/s
