The correct statements are "Each orbit holds a fixed number of electrons" and "The n=1 orbit can only hold two electrons." According to the Bohr model, the maximum number of electrons that can occupy an orbit is given by , where n is the number of the orbit. For instance, when n=1 it means
. This particular orbit can only hold up to two electrons. Even though the electrons can gain energy and move to higher orbits or electrons from higher orbits can lose energy and drop to the n=1 level, the energy level would not allow more electrons to enter the orbit once it is full. Again the octet rule, which states that atoms achieve stability by having 8 valence electrons, limits the maximum number of electrons that can be occupied by an orbit. The gain and loss of electrons is done to achieve the noble gas configuration and once that is reached no more electron can be added to an orbit
Answer:
= 19 Ω, I = 0.105 A, V1 = 1.05 V and V2 = 0.95 V
Explanation:
The correct way to solve this type of problem is to find the current or voltage values for the equivalent resistance and from here find the other values.
For a series circuit the equivalent resistance is the sum of the resistance
= R1 + R2
= 10 +9
= 19 Ω
Let's use the equation for the voltage
V = I
I = V /
I = 2/19
I = 0.105 A
In a series circuit the current is constant, so let's use the voltage equation for each resistor
V1 = I R1
V1 = 0.105 10
V1 = 1.05 V
V2 = 0.105 9
V2 = 0.95 V
Note that the sum of this voltage is the total voltage applied.

Answer:
Force D
Explanation:
In order to answer the question, let's keep in mind that the force of gravity on an object on Earth is the attractive force exerted by the Earth on the object; its direction is always downward (towards the Earth's centre), and its magnitude is given by
F = mg
where m is the mass of the object and g is the acceleration of gravity.
It follows immediately that in the figure, the force of gravity is the only force acting downward: therefore, force D.
The other forces are called:
Force A: thrust (it is the forward force generated by the engines)
Force B: lift (it is the upward produced by the aerodynamics of the wings)
Force C: air resistance (it is the backward force due to the friction between the air and the surface of the plane)
