Answer:
The reading on the ammeter is 0 ampere
Explanation:
When two or more voltage sources are arranged in series as shown in the diagram, the resultant voltage is given by the sum of the voltages by taking into consideration the direction of the polarities of the voltage sources which can be either series aiding voltage source configuration or series opposing voltage source configuration
In the series aiding voltage source configuration, the positive terminal of one voltage source is connected to the negative terminal of the next voltage source such that the current flows in the same direction in both sources of the voltage in the circuit and the resultant voltage source is given by adding the individual voltage sources together
However, in the series opposing voltage source configuration, the positive terminal of one voltage source is connected to the positive terminal of the next voltage source such that the current flows in opposite direction in both voltage sources and the voltage across the entire voltage sources is given by finding the sum of the differences of the opposing voltage sources
The arrangement of the voltage sources in the question is one of a series opposing voltage configuration and the voltage across both voltage sources is given by subtracting one (usually the smaller voltage source) from the other as follows;
[tex]V_{(series \ opposing)}[/tex] = V₁ - V₂
Where;
V₁ = The voltage of one (usually the larger) of the voltage source = 1.5 V
V₂ = The voltage of the other voltage source = 1.5 V
Therefore;
[tex]V_{(series \ opposing)}[/tex] = 1.5 V - 1.5 V = 0 V
The reading on the ammeter = The current in the circuit, 'I', which is given as follows;
V = I·R
∴ I = V/R = 0/R = 0
I = 0 A (ampere)
The reading on the ammeter = I = 0 A (Current cannot flow without the presence of a voltage).

A vector quantity is : A deer running 15 meters per second due west
Answers
Answer:
True.
Explanation:
Velocity can be defined as the rate of change in displacement (distance) with time. Velocity is a vector quantity and as such it has both magnitude and direction.
Mathematically, velocity is given by the equation;
[tex]Velocity = \frac{distance}{time}[/tex]
Simply stated, a vector quantity has both magnitude and direction.
Thus, a vector quantity is: A deer running 15 meters per second due west.

you walk 12 meters north, then 10 meters west. What is your displacement
Answers
Answer:
Your displacement is 15.62m NW
Explanation:
We can use the Phytagorean theorem to determine the displacement:
a^2+b^2=c^2
12^2+10^2=c^2
144+100=c^2
244=c^2
15.62=c
So your displacement is 15.62m NW

How would the model change as the atom forms bonds? The third shell would have eight electrons after the atom gains seven electrons to fill the outermost shell. The third shell would be empty so that the eight electrons in the second level would be outermost after the atom loses one electron. The first and third shells would be empty so that the atom would have eight electrons in its remaining shell after the atom loses three electrons. The first shell would have two electrons and the second shell would have six electrons after the atom loses three electrons.
Answers
Answer:
The third shell would be empty, so the eight electrons on the second level would be the outermost after the atom lost one electron
Explanation:
When an atom is bonded with other atoms, a more stable configuration must be reached, which is why the energy of the molecule is less than the energy of the individual atoms, for this to happen in general, electrons are shared or lost and gained in each atom, depending on the electronegative of the same.
If we analyze an atom within the molecule, its last shell is full, in the case of atoms with few electrons in this shell, they are lost and in the case of many electors in this shell, it gains electrons to have eight (8) in total.
When reviewing the different answers, the correct one is:
* The third shell would be empty, so the eight electrons on the second level would be the outermost after the atom lost one electron

A fixed source charge particle of 4.1 nC and a second particle with a charge 2.4 nC are separated by a distance of 3.5 cm. What is the electric potential energy between the particles? And if the second particle is released will it move forward or away from the source charge
Answers
Answer:
a. 2.53 μJ b. It will move away
Explanation:
a. What is the electric potential energy between the particles?
The electric potential energy U = kq₁q₂/r where k = 9 × 10⁹ Nm²/C², q₁ = 4.1 nC = 4.1 × 10⁻⁹ C, q₂ = 2.4 nC = 2.4 × 10⁻⁹ C and r = distance between charges = 3.5 cm = 3.5 × 10⁻² m.
Substituting the values of the variables into U, we have
U = kq₁q₂/r²
U = 9 × 10⁹ Nm²/C² × 4.1 × 10⁻⁹ C × 2.4 × 10⁻⁹ C/3.5 × 10⁻² m
U = 88.56 × 10⁻⁹ Nm²/3.5 × 10⁻² m
U = 25.3 × 10⁻⁷ Nm
U = 2.53 × 10⁻⁶ Nm
U = 2.53 × 10⁻⁶ J
U = 2.53 μJ
b. And if the second particle is released will it move forward or away from the source charge.
It will move away from the source charge since they have the same sign of charge. Since, opposite charges repel.
Answer:2.5 * 10^6 J away
Explanation:Using the equation PE = 9 * 10^9 * q1 * q2 / r,
where q is charge and r is distance. In this case, the equation would be
9*10^9{(4.1* 10^-9) * (2.4*10^9)/0.035} = 2.5 * 10^6. Both are positive, so they will be away.

A rock is thrown horizontally off a cliff with an initial velocity of 15 m/s. How high was the cliff if the rock lands 22 m from the base of the cliff?
Answers
Answer:
22 m
Explanation:
Answer:
cliff height = 10.55 m
Explanation:
Remarks
This is one of those questions that defies belief. The final vertical velocity is the same as if you just dropped the rock, which is amazing.Another amazing fact is that the horizontal speed has no acceleration. And amazing fact number three is the the vertical initial speed is 0.And finally, the time taken to go horizontally = time to go vertically.Solution
Time
So the time taken is d = r * t
Remember, this formula can only be used when there is no acceleration.
d = 22 meters
r = 15 m/s
t = ?
t = d / r
t = 22 / 15
t = 1.467
Height of the Cliff
vi = 0 (vertially)
a = 9.8 m/s^2
t = 1.467 seconds The time horizontally and vertically is the same.
d = ?
Formula
d = vi*t + 1/2 a t^2
Solution
d = 0 + 1/2 * 9.8 * 1.467^2
d = 10.55 meters.
