Answer: Ionization energy is the amount of energy necessary to <u>remove an electron from an atom</u>
Explanation:
Ionization consists of the production of ions, which are electrically charged atoms or molecules due to the excess or lack of electrons with respect to a neutral atom or molecule.
In this sense, ionization energy is the <u>energy necessary to separate (remove) an electron from a gaseous atom</u>, isolated and in a fundamental state. This is because <u>electrons are strongly attracted to the nucleus and it is necessary to provide energy to separate them</u>. However, where the atom always loses electrons is in the last layer, which is where the weakest electrons are attracted to the nucleus.
<h3>
Answer:</h3>
1.3 Amps
<h3>
Explanation:</h3>
<u>We are given;</u>
A circuit with resistors, R1 and R2
R1 = 7 Ω
R2 = 11 Ω
Voltage = 24 V
We are required to calculate the current in the circuit.
<h3>Step 1: We need to find the effective resistance.</h3>
When resistors are arranged in series, the effective resistance is calculated by;
Rt = R₁ + R₂ + R₃ + ..........Rₙ
Therefore;
Total resistance = 7 + 11
= 18 Ω
<h3>Step 2: Calculate the current in the circuit</h3>
From the ohm's law;
V = IR
Rearranging the formula;
I = V/R
Thus;
I = 24 V ÷ 18 Ω
= 1.333 Amps
= 1.3 Amps
Thus, the current in the circuit is 1.3 Amps
Answer:
the height of the cliff is equal to 108.241 m
Explanation:
given,
initial speed of the stone horizontally = 9 m/s
vertical speed of the stone = 0 m/s
time taken of the trajectory = 4.7 s
using equation of motion
![s = ut + \dfrac{1}{2}at^2](https://tex.z-dn.net/?f=s%20%3D%20ut%20%2B%20%5Cdfrac%7B1%7D%7B2%7Dat%5E2)
![s =0 \times 4.7 + \dfrac{1}{2} \times 9.8 \times 4.7^2](https://tex.z-dn.net/?f=s%20%3D0%20%5Ctimes%204.7%20%2B%20%5Cdfrac%7B1%7D%7B2%7D%20%5Ctimes%209.8%20%5Ctimes%204.7%5E2)
![s = 0 + 4.9 \times 4.7^2](https://tex.z-dn.net/?f=s%20%3D%200%20%2B%204.9%20%5Ctimes%204.7%5E2)
![s = 4.9 \times 22.09](https://tex.z-dn.net/?f=s%20%3D%204.9%20%5Ctimes%2022.09)
s = 108.241 m
hence, the height of the cliff is equal to 108.241 m
