Inside an atom, the strongest force is the Strong Nuclear Force, indicated by option A.
The strong nuclear force is one of the fundamental forces of nature and plays a crucial role in binding the subatomic particles, specifically protons and neutrons, within the atomic nucleus.
The strong nuclear force is responsible for overcoming the electrostatic repulsion between positively charged protons in the nucleus. It acts over extremely short distances, on the order of femtometers (10^-15 meters), and is characterized by its strength and short range. It is about 100 times stronger than the electromagnetic force, which is responsible for the interaction between charged particles.
The electromagnetic force, option B, is the second strongest force inside an atom. It is responsible for the interaction between charged particles, such as electrons and protons. The electromagnetic force is involved in holding the electrons in orbit around the nucleus and determines the chemical properties of atoms.
Gravity, option C, is the weakest force among the fundamental forces. While gravity plays a significant role on a macroscopic scale, such as the gravitational attraction between planets or objects on Earth, its influence at the atomic level is negligible compared to the strong nuclear and electromagnetic forces.
The weak nuclear force, option D, is another fundamental force, but it is responsible for processes such as radioactive decay and neutrino interactions. While it is involved in certain nuclear reactions, it is not as strong as the strong nuclear force.
In summary, the strong nuclear force is the strongest force inside an atom, overcoming the electrostatic repulsion between protons and binding the atomic nucleus together. Option A.

Write a multiple-choice question that requires the reader to understand that velocity and acceleration can have opposite signs.
Answer:
Please find the answers in the below explanation
Explanation:
Example of a multiple-choice question that requires the reader to understand that velocity and acceleration can have opposite signs is;
to consider a body that is moving with a speed of 20m/s and coming to rest by decelerating at about 4m/s^2
in this scenario,
The acceleration will be negative. That is, -4m/s^2
The final velocity V will be equal to zero. that is, V = 0
And the initial velocity U will be positive, That is, U = 20m/s
In the example above, you will notice that the initial velocity and the acceleration are of the opposite sign.

You are in an airplane circling an airport at a speed of 600 km/hour on a circular path of radius 3 km. A stewardess accidentally drops a cup , of mass .1 kg, on the floor. She releases it from rest at a perpendicular distance of 1.5 m from the floor. (That is to say, the shortest distance from the cup to a spot on the floor is 1.5 m.)
a) Show that the cup hits the closest point on the floor when it falls to good approximation.
b) What is its speed, relative to the airplane, when it hits the floor? (That is what is the magnitude of the velocity of the cup, measured in the reference frame of the airplane?) Show that it is somewhat higher than it would be if the cup dropped the same distance in an inertial reference frame.
Answer:
a) (0.0004·[tex]\mathbf{\hat i}[/tex] - 1.55·[tex]\mathbf{\hat j}[/tex]) m
b) 0.31 km/h·[tex]\mathbf{\hat i}[/tex] + 0.00008 km/h·[tex]\mathbf{\hat j}[/tex]
Explanation:
The given parameters are;
The circular motion of the airplane = 600 km/hour
The radius of the circular path = 3 km
The time it takes the cup to reach the floor of the airplane is given as follows;
s = u·t + 1/2·g·t²
1.5 = 1/2 × 9.81 × t²
t² = 1.5/(1/2 × 9.81)
t = √(1.5/(1/2 × 9.81)) ≈ 0.553 s
The location of the plane in 0.533 s is 600 km/hour × 0.533 s ≈ 83.83 meters
The angular velocity, ω = v/r = 600 km/hour/3 km = 200°/hour
Therefore, the angle covered in 0.533 s is 0.533 s × 200°/hour ≈ 0.0296°
tan(0.0296)*3000 ≈ 1.55 m vertical
3000 - cos(0.0296)*3000 ≈ 0.0004 m horizontal
The location of the cup relative to the plane will be
0 - (-0.0004·i + 1.55·j) = 0.0004·i - 1.55·j m
b) The speed of the cup relative to the plane when it hits the floor is given by the
The speed of the plane = 600 km/hour × cos(90 - 0.0296)j + 600 km/hour × sin(90 - 0.0296)j = -0.31 km/hour·i + 599.99 km/hour·j
The speed of the cup = 600 km/hour·j
The relative speed = 600 km/hour·j - ( -0.31 km/hour·i + 599.99 km/hour·j) = 0.31 km/hour·i + 0.00008 km/hour·j
The relative speed of the cup to the plane = 0.31 km/h·i + 0.00008 km/h·j
Therefore, given that there will be no relative speed in an inertia frame, the speed of the cup relative to the plane will be higher than when dropped in an inertia frame
An object is moving back and forth on the x-axis according to the equation x(t) = 3sin(20πt), t> 0, where x(t) is measured in cm and t in seconds. Give decimal answers below. (a) How many complete back-and-forth motions (from the origin to the right, back to the origin, to the left and finally back to the origin) does the object make in one second? (b) What is t the first time that the object is at its farthest right? (c) At the time found in part (b), what is the object's velocity? (d) At the time found in part (b), what is the object's acceleration?
Answer:
a.) 10Hz
b.) 0.1 s
c.) 187.4 m/s
d.) -412.6 m/s^2
Explanation:
Given that an object is moving back and forth on the x-axis according to the equation x(t) = 3sin(20πt), t> 0, where x(t) is measured in cm and t in seconds. Give decimal answers below.
(a) How many complete back-and-forth motions (from the origin to the right, back to the origin, to the left and finally back to the origin) does the object make in one second?
from the equation given, the angular speed w = 20π
but w = 2πf
where f = frequency.
substitute w for 20π
20π = 2πf
f = 20π/2π
f = 10 Hz
(b) What is t the first time that the object is at its farthest right?
since F = 1/T
T = 1 / f
T = 1/10
T = 0.1 s
Therefore, the t of first time that the object is at its farthest right is 0.1 s
(c) At the time found in part (b), what is the object's velocity?
The velocity can be found by differentiating the equation;
x(t) = 3sin(20πt)
dx/dt = 60πcos(20πt)
where dx/dt = velocity V
V = 60πcos(20π * 0.1)
V = 187.4 m/s
(d) At the time found in part (b), what is the object's acceleration?
to get the acceleration, differentiate equation V = 60πcos(20πt)
dv/dt = -1200πSin(20πt)
dv/dt = acceleration a
a = -1200πSin(20πt)
substitute t into the equation
a = -1200πSin(20π * 0.1)
a = - 412.6 m/s^2
The type of motion the object undergoes that consist of a back-and-forth
movement that is repetitive is a simple harmonic motion.
The correct responses are;
(a) Number of complete back-and-forth motions per second is 10(b) The first time is after 0.025 seconds(c) Velocity is 0(d) Acceleration is approximately -11843.53 m/s²Reasons:
The equation that represents the motion of the object is x(t) = 3·sin(20·π·t)
Where;
t ≥ 0
x(t) is in cm, and t is in seconds.
(a) The general sine function is y = A·sin(B·(t - C) + D
[tex]\mathrm{The \ period \ P} = \dfrac{2 \cdot \pi}{B}[/tex]
By comparison, we have;
B = 20·π
Therefore;
[tex]P = \dfrac{2 \cdot \pi}{20 \cdot \pi} = \dfrac{1}{10} = 0.1[/tex]
The period, which is the time to complete one cycle = 0.1 seconds
The number of cycle completed per second, is the frequency, f
[tex]f = \dfrac{1}{P} = \dfrac{1}{0.1} = 10[/tex]
f = 10 Hz = 10 cycles
The number of cycle completed per second is f = 10 cycles
(b) When the object is at the farthest right, we have;
sin(20·π·t) = Maximum = 1
[tex]\mathbf{sin\left(\dfrac{\pi}{2}\right)} = 1[/tex]
Therefore,
[tex]20 \cdot \pi \cdot t = \dfrac{\pi}{2}[/tex]
[tex]t = \dfrac{\pi}{20 \cdot \pi \cdot 2} = \dfrac{1}{40} = 0.025[/tex]
The first time it is at the farthest right is t = 0.025 seconds after start
(c) [tex]\mathrm{Velocity, \ v, \ is \ given \ by \ v = \dfrac{dx(t)}{dt}}[/tex]
Therefore;
[tex]v = \dfrac{dx(t)}{dt} = \dfrac{dx(t)}{dt} \left(3 \cdot sin \left(20 \cdot \pi \cdot t \right) = 60\cdot \pi \cdot cos \left(20 \cdot \pi \cdot t \right)[/tex]
At t = 0.25 seconds, we have;
[tex]v = \dfrac{dx(t)}{dt} = 60\cdot \pi \cdot cos \left(20 \times \pi \times 0.025 \right) = 0[/tex]
The velocity of the object at the t = 0.025 seconds is v(t) = 0
(d) Acceleration, a, is given by [tex]a = \dfrac{dv(t)}{dt}[/tex]
Therefore;
[tex]a = \dfrac{dv(t)}{dt} = \dfrac{d}{dt} \left( 60\cdot \pi \cdot cos \left(20 \times \pi \times t\right) \right) =-1200 \cdot \pi ^2 \cdot sin(20 \cdot t \cdot \pi)[/tex]
a = -1200·π²·sin(20·t·π)
∴ a = -1200×π²×sin(20×0.025×π)
sin(20×0.025×π) = 1
∴ a = -1200×π²×1 ≈ -11843.53
At the time found in part b the acceleration of the object, a ≈ -11843.53 m/s²

Zach listed the process of how laser beams are produced with crystals.
A flashlamp pumps energy through the crystal.
Atoms in the crystal absorb and then release some of the energy as light.
Light bounces off mirrors and occasionally bounces off crystal atoms, increasing in energy.
Some light escapes the tube through the highly reflective mirror, forming a concentrated beam.
Which best describes Zach’s error?
The crystal pumps energy through the flashlamp; the flashlamp does not pump energy through the crystal.
The atoms in the crystal do not release energy; they only absorb energy.
Light does not bounce off mirrors; it focuses through glass lenses.
Light escapes through the partially reflective mirror, not the highly reflective mirror.

What happens to the change in the value of the speed as you increased the amount of force applied on your
chosen Item
If you increased the amount of force applied on your chosen Item, rate of increase of its velocity with time will increase.
What is force?An object's push or pull is seen as exerting a force. The interaction of the objects produces push and pull. You can also use words like stretch and squeeze to describe force.
The definition of force in physics is: the push or pull on a mass-containing item changes its velocity.
An external force is an agent that has the power to alter the resting or moving condition of a body. It has a direction and a magnitude. The application of force is the location at which force is applied, and the direction in which the force is applied is known as the direction of the force.
So, if you increased the amount of force applied on your chosen Item, its acceleration will be increased and rate of increase of velocity with time will increase.

The speed of a river boat is 40 km/h and the rate of flow of the
river is 8 km/h. Moving along the same direction as the flow of
the river, the boat traveled 240 km. Calculate the distance the
boat could travel going against the stream in the same time
period.
Answer:
Distance the boat would travel going upstream = 160 km
Explanation:
First, the time of travel of the boat downstream is calculated.
Time of travel = distance/speed
distance = 240 km;
speed of travel = 40 + 8 = 48 km/h ( since the boat is going downstream)
Time = 240/48 = 5 hours
Therefore, the boat travels for 5 hours.
The distance the boat will travel in 5 hours going upstream is then calculated
distance = speed * time
speed of boat going upstream = 40 - 8 = 32 km/h
Distance = 32 km/h * 5 hours = 160 km

store at a constant velocity of 2.5 m/s for 65 s. How far is
the person from the store now?
Answer:
362.5 m away
Explanation:
Given a constant velocity of 2.5m/s, a time of 65s, and the initial displacement 200m or initial position. Displacement is basically the difference between the objects position regarding time.
The final displacement is found by: s = 1/2(v+v1)t + s1. Since the velocity is constant, the final velocity will be the same as the initial. S = 1/2(2.5m/s+2.5m/s)65 + 200 m = 2.5m × 65 m + 200m = 162.5m + 200m = 362.5m

A rock on the ground weighs 40N. How much force does the ground exert on the rock?
A. 20n
B. 0N
C.40n
Answer:
The correct option is;
C. 40 N
Explanation:
Given that the rock is on the ground, we have;
The weight of the rock, [tex]F_W[/tex] = 40 N ↓
From Newton's third law of motion, we have that action and reaction are equal and opposite,
Therefore, given that the weight of the rock exerts a force of 40 N on the ground, and the rock is stable and stationery on the ground, then the ground is reacting to the weight of the rock with an equal force of 40 N, acting in opposite direction to the weight of the block to balance the weight of the rock and create equilibrium such that the net force acting on the rock is zero
∑F = [tex]F_W + F_R[/tex] = 0
Where;
[tex]F_R[/tex] = The reaction of the ground
We have;
[tex]F_W[/tex] + [tex]F_R[/tex]= 40 + [tex]F_R[/tex] = 0
[tex]F_R[/tex] = 0 - 40 = -40
[tex]F_R[/tex] = -40 N ↓
∴ [tex]F_R[/tex] = 40 N ↑.

Newtons first law of motion states that if the net force on an

then the motion of the
object does not change.
Hurry please!
Answer:
Newton's first law of motion describes inertia. According to this law, a body at rest tends to stay at rest, and a body in motion tends to stay in motion, unless acted on by a net external force.
If the net force on an object is zero, then the motion of the object does not change.
What is Newton's first law of motion?According to Newton's first law, a body will stay at rest or continue to move in a straight line at a constant speed if it is at rest or moving in that direction without being subjected to external forces. In truth, moving uniformly in a straight line and remaining at rest have very little in common, according to classical Newtonian mechanics; they can both be thought of as the same state of motion as seen by different observers, one of whom moves at the same speed as the particle and the other who moves at constant speed in relation to the particle. The law of inertia is a name for this premise.
Newton's first law of motion states that if the net force on an object is then the motion of the object does not change.
