A good health can be defined as the state of well-being (wellness) in which all of the components of an individual's health are balanced. These state of wellness comprises of six (6) important components and they are;
1. Physical: this is a measure of the state of an individual's body or the way the body functions. It is enhanced by eating right, working out or exercising, avoiding drugs and alcohol, maintaining a good body mass index etc.
2. Emotional: this deals with the state of an individual's mind being void of worries, negativity etc.
3. Social: this involves keeping a good relationship with friends, family and many others around.
4. Environmental: it deals with maintaining a hygienic surrounding, that is devoid of pollutants.
5. Mental or intellectual: avoiding unnecessary stress and anxiety while dealing or coping with the realities of life.
6. Spiritual: it encompasses belief systems, values, ideals, morality etc.
Hence, when an individual is able to balance all of these above mentioned components, then he or she is said to be healthy.
A 10 kg bowling ball would require what force to accelerate down an alley at a rate of 3 m/s2? what is the net force?
Answer:
a. Force = 30N
b. Fnet = 128N
Explanation:
Given the following data;
Mass = 10 kg
Acceleration = 3m/s²
a. To find the force;
Force = mass * acceleration
Substituting into the equation, we have
Force = 10 * 3
Force = 30N
b. To find the net force;
Mathematically, net force is given by the formula;
Fnet = Fapp + Fg
Where;
Fnet is the net force. Fapp is the applied force. Fg is the force due to gravitation.We know that acceleration due to gravity is equal to 9.8m/s²
To find the gravitational force;
We know that acceleration due to gravity, g = 9.8m/s²
Fg = mg = 10*9.8 = 98N
Substituting into the equation, we have;
Fnet = 30 + 98
Fnet = 128N

Explanation:
train with a mass of 485000 kg. suppose the train is traveling northwest along a straight track at a speed of 20m/s. what force must the train exert to increase its velocity to 25.0m/s to the northwest in 5.00s
Answer:
Force = 485000 Newton.
Explanation:
Given the following data;
Mass = 485000 kg
Initial velocity = 20m/s
Final velocity = 25m/s
Time, t = 5 seconds
To find the force;
First of all, we would calculate the acceleration of the train i.e the rate of change of the velocity of the train with respect to time.
Mathematically, acceleration is given by the equation;
[tex]Acceleration (a) = \frac{final \; velocity - initial \; velocity}{time}[/tex]
[tex]a = \frac{v - u}{t}[/tex]
Where;
a is acceleration measured in [tex]ms^{-2}[/tex]
v and u is final and initial velocity respectively, measured in [tex]ms^{-1}[/tex]
t is time measured in seconds.
Substituting into the equation, we have;
Acceleration = (25 - 20)/5
Acceleration = 5/5
Acceleration = 1m/s²
Force is given by the multiplication of mass and acceleration.
Mathematically, Force is;
Force = mass * acceleration
Force = 485000 * 1
Force = 485000 Newton.
Which of these requirements must be met by two physical quantities when they are added together?
They must have different units when expressed in base units.
They must both have units of kilograms, meters, or seconds.
They must have the same units when expressed in base units.
They must have been given to you in the same units, such inches or centimeters.
Answer:
They must have the same units when expressed in base units
Explanation:
Too add any two values together you need them to be in the same units. but You can convert diffrent units of the same messure to each other in order to achive this; ie you can add meeters to feet if you multiply the meters by 3.28 but you can't add mass and length together.
With the concept of pattern we find that the answer for the sum of physical magnitudes is:
They must have the same units when expressed in base units.
To add two phsical quantities to meet some requirements:
* Must be of the same type
* Must be in the same base units
That they have the same type implies that we cannot add length with time or masses, length or speeds must be added with their pairs
The use of the same base unit guarantees that we use the same pattern, or that we must reduce the magnitudes to the same pattern, for example: we cannot add meters with inches directly, we must reduce inches to meters, which is the unit of the international system.
International System it guarantees the existence of common and reproducible patterns for all physical quantities.
Add two phsical quantities, the correct answer is:
must have the same units in base units
In conclusion, the measurement system and units allows adding magnitude of the same type with the same units of a base unit or standard.

83. A sailboat travels south at 12.0 km/h with respect to the
water against a current 15.0° south of east at 4.0 km/h.
What is the boat's velocity?
Answer:
The magnitude of the boat's velocity is 8.21 km/h.
Explanation:
We can find the boat's velocity as follows:
[tex] \Epsilon V_{x} = V_{w_{x}} + V_{b_{y}} [/tex]
[tex] \Epsilon V_{y} = V_{w_{y}} + V_{b_{y}} [/tex]
Where:
[tex]V_{w_{x}}[/tex] and [tex]V_{w_{y}}[/tex] are the components of the velocity of the water in the x and y-direction
[tex]V_{b_{x}}[/tex] and [tex]V_{b_{y}}[/tex] are the components of the velocity of the boat in the x and y-direction
Since the angle is 15° we have:
[tex] \Epsilon V_{x} = -4.0 km/h*sin(15) + 0 = -1.04 km/h [/tex]
[tex] \Epsilon V_{y} = 4.0 km/h*cos(15) - 12.0 km/h = -8.14 km/h [/tex]
Now, the velocity of the boat is:
[tex] V = \sqrt{V_{x}^{2} + V_{y}^{2}} = \sqrt{(-1.04 km/h)^{2} + (-8.14 km/h)^{2}} = 8.21 km/h [/tex]
Therefore, the magnitude of the boat's velocity is 8.21 km/h.

Physicists often use a different unit of energy, the electron volt, when dealing with energies at the atomic level. One electron volt, abbreviated eV, is defined as the amount of kinetic energy gained by an electron upon accelerating through a 1.0 V potential difference.
a) what is 1.0 electron volt in joules?
b) what is the speed of a proton with 5000 eV of kinetic energy?
Answer:
a) E = 1.06 10⁻¹⁹ J, b) v = 9.78 10⁵ m / s
Explanation:
The physical magnitudes can be given in several units, but in general all must be reduced to the same system in a given exercise, the most used system is the international (SI)
1 eV =q V= 1.6 10⁻¹⁹ J
let's reduce the quantities requested
a) E = 1.0 eV to Joule
E = 1.0 eV (1.6 10⁻¹⁹ J / 1 eV)
E = 1.06 10⁻¹⁹ J
b) the kinetic energy is given by
K = ½ m v²
v = [tex]\sqrt{\frac{2K}{m} }[/tex]
the mass of the proton is
m = 1,673 10⁻²⁷ kg
let's reduce the energy to the SI system
E = 5000 ev (1.6 10-19 J / 1 eV) = 8000 10⁻¹⁹ J
let's calculate
v = [tex]\sqrt{ \frac{2 \ 8000 \ 10^{-19}}{1.673 \ 10^{-27} } }[/tex]
v = [tex]\sqrt{ 95.637 \ 10^{10} }[/tex]
v = 9.78 10⁵ m / s
To determine exactly where a satellite is located, engineers must think and calculate positions in three dimensions. A set of data telling engineers all of the various elements of position, velocity, and time for a satellite or spacecraft is known as a:
Answer:
State vector.
Explanation:
To determine exactly where a satellite is located, engineers must think and calculate positions in three dimensions. A set of data telling engineers all of the various elements of position, velocity, and time for a satellite or spacecraft is known as a state vector.
This ultimately implies that, state vectors gives a detailed description of the position and velocity of a satellite at a specific period of time. Also, the more accurate your input state vector, the more accurate would be the position, velocity and time for a satellite when trying to determine its location. Therefore, the time tag of a state vector shouldn't be too far from the present time of the day.
Suppose 2 C of positive charge is distributed evenly throughout a sphere of 1.27 cm radius. (a) What is the charge per unit volume for this situation? C/m3 (b) Is the sphere insulating or conducting? How do you know? The sphere is conducting. If it were insulating, none of the charge would be in the interior of the sphere; it would only be on the surface. The sphere is insulating. If it were conducting, none of the charge would be in the interior of the sphere; it would only be on the surface. The sphere is conducting. If it were insulating, all of the charge would be in the interior of the sphere; not on the surface. The sphere is insulating. If it were conducting, all of the charge would be in the interior of the sphere; not on the surface.
Answer:
a) ρ = 2.33 10⁵ C / m³, b) INSULATING
Explanation:
a) For this exercise we use the important concept of density
ρ = Q / V
The volume of a sphere is
V = 4/3 πr3
V = 4/3 π (1.27 10⁻²)³
V = 8.58 10⁻⁶ m³
let's calculate
ρ = 2 / 8.58 10⁻⁶
ρ = 2.33 10⁵ C / m³
b) in a conductor the charges are mobile, therefore due to electoral repulsion all the charges must concentrate on the surface.
In an insulator the charges are fixed, therefore they are distributed throughout the volume
Consequently the sphere must be INSULATING
Two charges that are both 5 C push each other apart with a force of 762,149 N. How far apart are the two charges?
Answer:
543.04 m
Explanation:
The 2 charges are:
q1 = q2 = 5 C
Distance apart is r
Force; F = 762149 N
We will use the formula from coulumbs law;
F = kq1•q2/r²
Where k is coulumbs constant = 8.99 × 10^(9) N.m²/C²
Making r the subject, we have:
r = √((8.99 × 10^(9) × 5 × 5)/762149)
r ≈ 543.04 m

A book is sitting on the dashboard of a car that is stopped at a traffic light as the car starts to move forward the book slides backward off the dashboard what does the book actually do
Answer:
The book remained in its state of rest before the car started to move forward as no direct force acted on it.
Explanation:
According to Newton's first law of motion, a body will continue in its present state of rest, or if it is in motion, will continue to move with uniform speed in a straight line unless aced upon by an external force. This tendency of a body to remain in its state of reset or uniform motion in a straight line is known as inertia and is directly proportional to the mass of the body. The more massive a body, the more inertia it possesses. Thus Newton's first law is also known as the law of inertia.
Considering the case of the book on the dashboard of a stationary car which suddenly starts to move. While the car is stopped at the traffic light, the dashboard where the book sits and the book are both at rest. When the car begins to move forward, the dashboard moves forward with it. However as the book is not a part of the car, no force is directly acting on it, so the book so it stays at rest due to its inertia.
Therefore, as the car is moving forward, the stationary book appears to move backward from the reference point of the car, sliding off the dashboard.

1.Particles are spaced the farthest apart in _____ and are the closest in ______. Select the answer that best completes the sentence.
liquids; solids
gases; liquids
solids; gases
gases; solids
Answer:
gases; solids.
Explanation:
gases take up the most volume, meaning the particles are more spread apart (disorder, entropy, etc. if you are familiar with those). solids have the particles closer together, opposite of gases.
Particles are spaced the farthest apart in gases and are the closest in solids.
Gases consist of very large numbers of tiny spherical particles that are far apart from one another compared to their size. Gas particles are in constant rapid motion in random directions.
The particles in solids are arranged in a regular way. The particles in solids move only by vibrating about a fixed position. This gives solids a fixed shape and means that they cannot flow like liquids. The hotter a solid gets, the faster its particles vibrate.
What are particles ?"A particle is a small piece of anything. Particle can also refer to a subatomic particle with mass and structure, but takes up hardly any space at all. Particles are tiny."

Antenna size of TVs and cell phones is related to the size of the _________ used by the technology.
Answer:
Electromagnetic waves.
Explanation:
Electromagnetic waves is a propagating medium used in all communications device to transmit data (messages) from the device of the sender to the device of the receiver.
Antenna size of TVs and cell phones is related to the size of the electromagnetic waves used by the technology.
This ultimately implies that, size of the electromagnetic waves plays a significant role in choosing the appropriate size for antennas used in all telecommunications device such as television, mobile phone, radio, satellite, etc.
Generally, the most commonly used electromagnetic wave technology in telecommunications is radio waves.
Radio waves can be defined as an electromagnetic wave that has its frequency ranging from 30 GHz to 300 GHz and its wavelength between 1mm and 3000m. Therefore, radio waves are a series of repetitive valleys and peaks that are typically characterized of having the longest wavelength in the electromagnetic spectrum.
Basically, as a result of radio waves having long wavelengths, they are mainly used in long-distance communications such as the carriage and transmission of data.

A 2500-kg car is being pushed up a hill at an angle of 35 degrees. Determine the gravitational
force pulling down on the car if it is accelerating up the hill at a rate of 5 m/s/s.
Answer:
The force that pulls the car down is Wₓ = 14052.6 N and the one that pushes the car up is F = 26552.6 N
Explanation:
For this exercise we will use Newton's second law, let's set a reference system where the x axis is parallel to the plane, in the adjoint we can see the forces in the system.
sin 35 = Wₓ / W
cos 35 = W_y / W
Wₓ = W sin 35
W_y = W cos 35
Wₓ = 2500 9.8 sin 35
Wₓ = 14052.6 N
let's write the equations for each axis
and
Y axis
N-W_y = 0
N = W_y
X axis
F -Wₓ = m a
F = Wₓ + m a = mg sin 35 + m a
F = m (a + g sin 35)
let's calculate
F = 2500 (5 + 9.8 sin 35)
F = 26552.6 N
The force that pulls the car down is Wₓ = 14052.6 N and the one that pushes the car up is F = 26552.6 N
