The distance between Earth and its moon is 3.84 x 10 meters. Earth's mass is
m = 5.98 x 1024 kilograms and the mass of the moon is 7.36 x 1022 kilograms.
What is the force between Earth and the moon?
Answer:
The force between Earth and the moon is 1.99x10²⁶ N.
Explanation:
The force between Earth and the moon can be found using the Gravitational Force equation:
[tex] F_{g} = \frac{Gm_{E}m_{m}}{d^{2}} [/tex]
Where:
d: is the distance between Earth and the moon = 3.84x10⁵ m
G: is the gravitational constant = 6.67x10⁻¹¹ Nm²/kg²
[tex]m_{E}[/tex]: is the Earth's mass = 5.98x10²⁴ kg
[tex]m_{m}[/tex]: is the moon's mass = 7.36x10²² kg
Hence, the force is:
[tex] F_{g} = \frac{Gm_{E}m_{m}}{d^{2}} = \frac{6.67 \cdot 10^{-11} Nm^{2}/kg^{2}*5.98\cdot 10^{24} kg*7.36\cdot 10^{22} kg}{(3.84\cdot 10^{5} m)^{2}} = 1.99 \cdot 10^{26} N [/tex]
Therefore, the force between Earth and the moon is 1.99x10²⁶ N.

Why could the beam of particles not have a neutral charge?
Answer:
The positive and negative charges balance each other. Overall, the atom is uncharged (neutral). However, if something happens to make an atom lose or gain an electron then the atom will no longer be neutral. An atom that gains or loses an electron becomes an ion.

Billiard ball A, mass 0.17 kg, is moving due east with a velocity of 4.0
m/s. It strikes stationary billiard ball B, which has the same mass. After
the collision, ball A moves at an angle of 30° north of east with a
velocity of 3.5 m/s. Ball B moves at an angle of 60° south of east.
What is the speed of ball B?
Answer:
2 m/s
Explanation:
The momentum of the colliding system is conserved . Therefore, the velocity of the ball B with the same mass as A is 0.52 m/s.
What is momentum ?Momentum of a body is the ability to bring the applied force makes maximum displacement. it is the product of mass and velocity. For a collision, the sum of initial momentum of the two bodies is equal to the sum of their final momentum.
Thus, u be the initial velocity and v be the final velocity.
Then, m1 u1+ m2 u2 = m1 v1 + m1 v2
m1 = 0.17 kg
u1 = 4 m/s
m2 = 0.17 kg
u2 = 0
Then initial momentum = 0.17 × 4 m/s + 0 = 0.68 kg m/s
v1 = 3.5 m/s
0.68 kg m/s = (0.17 × 3.5 m/s ) + (0.17 × v2)
then v2 = 0.52 m/s.
Therefore, the velocity of ball B after collision will be 0.52 m/s.

Beta radiation consists of what type of sub-atomic particle
I have a voltage source of 12V but a light that only burns at 5V. The lamp works on 18 mA. Calculate the resistance that you EXTRA have to include in this series connection.
Answer:
The resistance that will provide this potential drop is 388.89 ohms.
Explanation:
Given;
Voltage source, E = 12 V
Voltage rating of the lamp, V = 5 V
Current through the lamp, I = 18 mA
Extra voltage or potential drop = 12 V - 5 V = 7 V
The resistance that will provide this potential drop (7 V) is calculated as follows:
[tex]R = \frac{V}{I} = \frac{7 \ V}{18 \times 10^{-3} A} \ = 388.89 \ ohms[/tex]
Therefore, the resistance that will provide this potential drop is 388.89 ohms.

A wave has a wavelength of 3.3 m and a speed of 5.6 m/s. What is the frequency of this wave
Answer: λ (wavelength) = 3.3 m → ΔS = 3.3 m
v (speed) = 5.6 m/s → ΔV = 5.6 m/s
T (period) → ΔT = ?
f (frequency) = ?
If:
Now: (if, ΔT = T), Using the formula of the period of a wave, find the frequency:
Explanation: Your Welcome u.u
The frequency of this wave is approximately 1.697 Hz.
To find the frequency of a wave, we can use the formula:
frequency (f) = speed (v) / wavelength (λ)
Given:
Wavelength (λ) = 3.3 m
Speed (v) = 5.6 m/s
Substituting these values into the formula, we can calculate the frequency:
f = v / λ
f = 5.6 m/s / 3.3 m
f ≈ 1.697 Hz
Therefore, the frequency of this wave is approximately 1.697 Hz.

A positively charged particle of mass 7.2 x 10-8 kg is traveling due east with a speed of 88 m/s and enters a 0.6-T uniform magnetic field. The particle moves through one-quarter of a circle in a time of 2.2 x 10-3 s, at which time it leaves the field heading due south. All during the motion the particle moves perpendicular to the magnetic field. Determine the magnitude of its charge in mC. (1 mC
Answer:
q = 8.57 10⁻⁵ mC
Explanation:
For this exercise let's use Newton's second law
F = ma
where force is magnetic force
F = q v x B
the bold are vectors, if we write the module of this expression we have
F = qv B sin θ
as the particle moves perpendicular to the field, the angle is θ= 90º
F = q vB
the acceleration of the particle is centripetal
a = v² / r
we substitute
qvB = m v² / r
qBr = m v
q =[tex]\frac{m\ v}{B\ r}[/tex]
The exercise indicates the time it takes in the route that is carried out with constant speed, therefore we can use
v = d / t
the distance is ¼ of the circle,
d = [tex]\frac{1}{4} \ 2\pi r[/tex]
d =[tex]\frac{\pi }{2r}[/tex]
we substitute
v = [tex]\frac{\pi r}{2t}[/tex]
r = [tex]\frac{2 \ t \ v}{\pi }[/tex]
let's calculate
r =[tex]\frac{2 \ 2.2 \ 10^{-3} \ 88}{\pi }[/tex] 2 2.2 10-3 88 /πpi
r = 123.25 m
let's substitute the values
q = [tex]\frac{ 7.2 \ 10^{-8} \ 88}{ 0.6 \ 123.25}[/tex]7.2 10-8 88 / 0.6 123.25
q = 8.57 10⁻⁸ C
Let's reduce to mC
q = 8.57 10⁻⁸ C (10³ mC / 1C)
q = 8.57 10⁻⁵ mC
You are hiking pine mountain and have finally reached the top. You are peering over the edge and accidentally drop your phone while taking pictures. Your phone falls and hit the
ground 13 seconds later. How tall is the mountain?
Answer:
The cliff is 12.71m tall.
Explanation:
Why?
Before solving the problem, we must remember that the phone was dropped, it means that there is no initial velocity, also, the acceleration acting on the phone is the acceleration due to gravity.
So, to find how tall is the cliff, we can use the following equations:
\begin{gathered}y=y_o+v_o*t-\frac{1}{2}g*t^{2}\\\\v_f=v_o+g*t\end{gathered}y=yo+vo∗t−21g∗t2vf=vo+g∗t
\begin{gathered}t=\frac{v_f}{g} \\\\t=\frac{-15.75\frac{m}{s}}{-9.81\frac{m}{s^{2}}}=1.61s\end{gathered}t=gvft=−9.81s2m−15.75sm=1.61s
Now that we know the time, we can calculate how tall is the cliff:
\begin{gathered}y=y_o+v_o*t+\frac{1}{2}g*t^{2}\\\\y=0+0*1.61s-\frac{1}{2}*(-9.81\frac{m}{s^{2}})*(1.61s)^{2}\\\\y=12.71m\end{gathered}y=yo+vo∗t+21g∗t2y=0+0∗1.61s−21∗(−9.81s2m)∗(1.61s)2y=12.71m

1. ELE to KE = Electrical energy conversion to kinetic energy.
2. KE to ELE = kinetic energy conversion to electrical energy.
3. CE to ELE = chemical energy conversion to electrical energy.
Explanation:
The Law of Conservation of Energy states that energy cannot be destroyed but can only be transformed or converted from one form to another.
Some examples of energy are chemical energy, electrical energy, kinetic energy, sound energy, potential energy, light energy, etc.
The transformation of energy from one form to another are described below;
1. A hair dryer plugged into the wall: it involves the conversion of electrical energy to kinetic energy. The energy type present in the wall socket is electrical energy which powers the hair dryer to have kinetic energy i.e the energy possessed due to motion of hair dryer.
2. A hand crank generator emergency radio: it illustrates the conversion of kinetic energy to electrical energy. The hand crank generator possess kinetic energy as it is being wounded before it is then converted into electrical energy which powers the radio.
3. A battery operated fan: it illustrates the conversion of chemical energy to electrical energy. The cells present in battery possess chemical energy that is being converted into electrical energy to power the fan.

Answer:
In a system with a hanging mass and an inextensible wire, the force is proportional to the sino, in the case of small oscillations, approximately the stop angle, this hiss is lost, the calibration for large amplitudes is lost.
Explanation:
In a spring-mass system the restoring force created by the spring is proportional to displacement from the equilibrium position, therefore this watch does not require streamlining as the amplitude of movement increases.
In a system with a hanging mass and an inextensible wire, the force is proportional to the sino, in the case of small oscillations, approximately the stop angle, this hiss is lost, the calibration for large amplitudes is lost.

17. If ice has a density of 0.92g/cm?, what is the mass of a 30 cm block?
I
Answer:
Mass = 27.6 grams
Explanation:
Given the following data;
Density of ice = 0.92g/cm³
Volume = 30cm³
To find mass of ice;
Density can be defined as mass all over the volume of an object.
Simply stated, density is mass per unit volume of an object.
Mathematically, density is given by the equation;
[tex]Density = \frac{mass}{volume}[/tex]
Making mass the subject of formula, we have;
[tex] Mass = density * volume [/tex]
[tex] Mass = 0.92 * 30 [/tex]
Mass = 27.6 grams
Therefore, the mass of ice is 27.6 grams.
