Answer:
False.
Explanation:
A public health license can be defined as series of privileges and authority granted to a practitioner in the public domain, to offer services to the general public after admitting to comply with the standards, rules and regulations set aside by health regulatory agencies and the government (both state and federal).
This ultimately implies that, all restaurant owners must have met the minimum requirements (criteria) and agree to comply with all the standards, rules and regulations with respect to public health before they are endorsed and then given a license to practice or operate by the appropriate agency or authorities.
Hence, restaurant owners agree to comply with state, federal, and health regulations when applying for a public health license.

A softball has a mass of 0.18 kg. What is the gravitational force on Earth due to the ball, and what is the Earth's resulting acceleration? Earth's mass is 6.0 x 1024 kg.
Answer:F=1.7802
Explanation:
Since we've been given the mass to be .18kg,we are asked to find the Force of which the formulae is
F=ma where f-force,m-mass and a-acceleration due to gravity
So we can just substitute
F-?.m=.18 and a9.89
F=.18×9.89
F=1.7802N
The gravitational force on Earth due to the ball will be 1..769 N . While the Earth's resulting acceleration will be 2.9 ×10²³ m/sec².
What is gravitational force?Newton's law of gravity states that each particle having mass in the universe attracts each other particle with a force known as the gravitational force
The given data in the problem is;
m is the mass of ball=0.18 kg
F is the gravitational force=?
m is the mass of earth= 6.0 x 1024 kg.
r is the radius of earth = 6.3781×106 m
G is the universal gravitational constant= 6.67408×10-11 Nm/kg2
The gravitational force is given by;
[tex]\rm F_G=\frac{ G m_1m_2}{r^2} \\\\ \rm F_G=\frac{ 6.67 \times 10^{-11} 0.18 \times 6.0 \times 10^{24}}{6.3781\times 10^6)2}[/tex]
[tex]\rm F_G= 1.769 N[/tex]
Hence the gravitational force on Earth due to the ball will be 1..769 N.
The force is given as the product of mass and acceleration. So that the value of acceleration is found by;
[tex]\rm a= \frac{F}{m} \\\\ \rm a= \frac{1.769}{6.0 \times 10^{24}}[/tex]
[tex]\rm a= 2.9 \times10^{-23}[/tex] m/sec²
Hence the Earth's resulting acceleration will be 2.9 ×10²³ m/sec².

An 18 000-kg freight car travelling 1.75 m/s[E] collides with a 27 000-kg freight car at rest. After the collision, the freight cars stick together. What is the velocity of the freight cars after the collision?
Answer:
The velocity of the freight cars after collision is 0.7 m/s
Explanation:
Given;
mass of the first freight car, m₁ = 18000 kg
initial speed of the first freight car, u₁ = 1.75 m/s
mass of the second freight car, m₂ = 27000 kg
initial speed of the second freight car, u₂ = 0
Let the velocity of the freight cars after collision = v
Apply the principle of conservation of linear momentum;
m₁u₁ + m₂u₂ = v(m₁ + m₂)
18000(1.75) + 27000(0) = v(18000 + 27000)
31500 = 45000v
v = 31500 / 45000
v = 0.7 m/s
Therefore, the velocity of the freight cars after collision is 0.7 m/s

if we bring a 200. kg lunar rover to the moon, what will happen to its mass and weights? (g=1.6 m/s2 on the moon)
Answer:
W = 320 [N]
Explanation:
In order to solve this problem, we must take into account that weight is defined as the product of mass by gravity.
[tex]W=m*g[/tex]
where:
W = weight [N] (units of Newtons)
m = mass = 200 [kg]
g = gravity acceleration = 1.6 [m/s²]

Which of these pairs of quantities is used to describe the transfer of energy to or from a substance? A. heat and work B. heat and kinetic energy C. work and potential energy D. potential energy and kinetic energy
Answer:
B. heat and kinetic energy
Explanation:
Heat is a form of energy that flows with respect to temperature difference. Thus, heat energy would flow from an object with higher temperature to that at lower temperature. It generally cascades from a high temperature body to lower temperature body through a medium or when in contact.
Kinetic energy is the energy that is inherent in a moving object. Thus, it can be converted to other forms or transferred between objects. Example, a moving object can transfer part of its kinetic energy to an object at rest on collision. This may cause the motion of the initial stationary object.
Therefore, heat and kinetic energy can be used to describe transfer of energy to or from a substance.

This diagram shows two different forces acting on a skateboarder. The
combined mass of the skateboard and the person is 65.2 kg. Based on this
information, what is the acceleration of the skateboarder?
Air resistance = 55.20 N
Applied force = 31.80
si
A. 0.36 m/s2 to the left
B. 1.46 m/s2 to the left
C. 0.36 m/s2 to the right
D. 1.47m/s2 to the right
Answer:
Option A. 0.36 m/s to the left
Explanation:
From the question given above, the following data were obtained:
Force resistance (Fᵣ) = 55.2 N
Applied force (Fₐ) = 31.8 N
Mass (m) = 65.2 kg.
Acceleration (a) =?
Next, we shall determine the net force acting on the skateboarder. This can be obtained as illustrated below:
Force resistance (Fᵣ) = 55.2 N
Applied force (Fₐ) = 31.8 N
Net force (Fₙ) =?
Fₙ = Fᵣ – Fₐ
Fₙ = 55.2 – 31.8
Fₙ = 23.4 N to the left
Finally, we shall determine the acceleration of the skateboarder. This can be obtained as follow:
Mass (m) = 65.2 kg.
Net force (Fₙ) = 23.4 N to the left
Acceleration (a) =?
F = ma
23.4 = 65.2 × a
Divide both side by 65.2
a = 23.4 / 65.2
a = 0.36 m/s
Since the net force acting on the skateboarder is to the left. Therefore, the acceleration of the stakeholder will also be towards the left (i.e 0.36 m/s to the left)
Answer:
A. 0.36 m/s to the left
By what factor will the Electrostatic Force between two charged objects change when the amount of charge on both objects doubles AND the distance between the two charged objects triples?
Answer:
F' = (4/9)F
Explanation:
The electrostatic force between two charged objects is given by Coulomb's Law:
F = kq₁q₂/r² -------------------- equation (1)
where,
F = Electrostatic Force
k = Coulomb's Constant
q₁ = magnitude of first charge
q₂ = magnitude of second charge
r = distance between charges
Now, when the charges and distance altered as follows:
q₁' = 2q₁
q₂' = 2q₂
r' = 3r
Then,
F' = kq₁'q₂'/r'²
F' = k(2q₁)(2q₂)/(3r)²
F' = (4/9)kq₁q₂/r²
using equation (1):
F' = (4/9)F

Why don't protons stick together?
Answer:
The protons must feel a repulsive force from the other neighboring protons. This is where the strong nuclear force comes in. ... If they can't get that close, the strong force is too weak to make them stick together, and other competing forces (usually the electromagnetic force) can influence the particles to move apart.^o^
Answer:
Because, they are of the same charge that is, + and +, + can't go with another +.

The air in a tire pump has a volume of 1.50L at a temperature of 5◦C. If the temperature is increased to 30◦C and the pressure remains constant, what is the new volume? Hurry Please!
Answer:
1.6L
Explanation:
Given parameters:
Initial volume = 1.5L
Initial temperature = 5°C = 5 + 273 = 278K
Final temperature = 30°C = 30 + 273 = 303K
Unknown:
Final or new volume = ?
Solution;
Since pressure is constant, we simply apply Charles's law to solve this problem.
Using the expression below,
[tex]\frac{V_{1} }{T_{1} }[/tex] = [tex]\frac{V_{2} }{T_{2} }[/tex]
V and T are volume and temperature
1 and 2 are initial and final states
Insert the parameters and solve;
[tex]\frac{1.5}{278}[/tex] = [tex]\frac{V_{2} }{303}[/tex]
278V₂ = 1.5 x 303
V₂ = 1.6L

which situation results in the most attraction between two magnets?
A. the north pole of one magnet is far away from the north pole of the other magnet.
B. the South pole of one magnet is near the South pole of the other magnet.
C. the north pole of one magnet is near the South pole of the other magnet.
D. The north pole of one magnet is far away from the South pole of the other magnet.
Answer:
C
Explanation:
Opposites attract, the north pole of one of the magnet is attracted to the south pole of the other magnet. Two north or south poles will repel away from each other.
The north pole of one magnet is near the South pole of the other magnet.
The ends of a magnet are called its poles. One end is called the north pole, the other is called the south pole. If you line up two magnets so that the south pole of one faces the north pole of the other, the magnets will pull toward each other. This is called attraction.
What is magnet ?"A magnet is a material or object that produces a magnetic field. This magnetic field is invisible but is responsible for the most notable property of a magnet: a force that pulls on other ferromagnetic materials, such as iron, steel, nickel, cobalt, etc. and attracts or repels other magnets."

The fact that objects fall to earth at the same speed is called
Answer:
The Equivalence Principle of Gravity
Explanation:
The fact that objects fall to earth at the same speed is called the Equivalence Principle of Gravity.
What is the Equivalence Principle of Gravity?According to the Equivalence Principle of Gravity, all things fall at the same rate when there is little to no air resistance. The value of the acceleration caused by gravity is demonstrated by the force of gravity equation to be a constant that is independent of the mass of the item.
According to Einstein's equivalence principle, it is unnecessary to distinguish between gravitational and inertial forces because they are comparable in nature.
The inertia force acts in the opposite direction of an object's accelerating force.As a result, the Einstein equivalence principle can be expressed as "the effects of gravity are exactly identical to the effects of acceleration."Therefore, the Equivalence Principle of Gravity states that all objects descend to Earth at the same rate.

In many situations, energy is lost to the work done by friction. But the law of conservation of energy says energy cannot be created or destroyed. So where does the "lost" energy go?
Answer:
Heat energy
Explanation:
The seemingly lost energy due to the work done by friction is lost to heat energy.
When we account for heat energy of the system, it is clearly seen that it is not lost as we perceive it.
The law of conservation of energy also suggests that energy is transformed and neither lost nor created. The work done by friction is transformed into heat energy of the system.Based on the graph, which data point is most likely to have experimental

What will the final velocity of a 5.0 g bullet starting from rest, if a net force of 45 N is applied over a distance of 0.80 m?
Answer:
The final velocity of the bullet is approximately 3.795 m/s
Explanation:
The given parameters are;
The mass of the bullet, m = 5.0 g
The force applied to the bullet, F = 45 N
The distance over which the force is applied, d = 0.80 m
Therefore, we have;
The final kinetic energy of the bullet = = 1/2 × m × v² = The work done on the bullet by the 45 N force = F × d
Where;
v = The final velocity of the bullet
By substitution, we get;
The final kinetic energy of the bullet = 1/2 × 5.0 × v² = 45 × 0.8
1/2 × 5.0 × v² = 45 × 0.8
v² = (45 × 0.8)/(1/2 × 5.0) = 14.4
v = √14.4 ≈ 3.795
The final velocity of the bullet = v ≈ 3.795 m/s
