Explain how the perfume atomizer works under Bernoulli's principle
Answer:
In an atomizer, or perfume sprayer, you squeeze a rubber bulb to squirt air through a tube. Because of the Bernoulli principle, the air rushing through the tube has a lower pressure than the surrounding atmosphere. ... The perfume is pushed out of the tube and sprays into the air as a fine mist.

A chunk of ice with a mass of 1.2 kg melts and absorbs 3.33 x 10³J of energy. Which best describes what has happened in this system?
Answer:
- Its entropy increases.
Explanation:
Entropy is defined as a 'measure of the amount of energy in a physical system that cannot be used to do work.' It is also employed to denote randomness, disorder, or uncertainty of the arrangement/system. In the given system, the melting of ice denotes the 'increase in entropy' as the amount of energy unavailable to do work increases('absorbs 3.33 x 10³J of energy'). Thus, this signifies that the entropy increases with a rise in temperature as it allows the substance to have greater kinetic energy.
The quantity of matter in an object. More specifically, it is the measure of the inertia that an object exhibits in response to any effort made to start it, stop it, or change in any way its state of motion
Answer:
Mass
Explanation:
The mass of an object expresses the amount of matter it comprises. Which implies that objects with higher mass contains higher matter compared to objects with lesser masses. Thereby it determines the measure of inertia experienced by an object when a force is applied to change its direction of motion, or to set it in motion when at rest, or bring it to rest when in motion.
The mass of an object the same no matter its location, and it is measured in kilograms.

Explain how water waves are not purely transverse waves
Answer:
Water waves are an example of waves that involve a combination of both longitudinal and transverse motions. As a wave travels through the waver, the particles travel in clockwise circles. The radius of the circles decreases as the depth into the water increases.

2. Which of the following changes on different celestial objects due to the
force of gravity?
A. mass
B. weight
C. height
D. width
Answer: The answer is B Hope this helps
Explanation:
An astronomical object is also called a celestial object. It is a naturally occurring physical entity. They are complex, have diverse structures and weights. They even have substructures.
The shape and size of the celestial objects within galaxies their mass, size weight, and galactic matter all make them different and hence exert a force of its gravity.Hence the option B is correct.

Which of these provides the best evidence for Newton’s First Law of Motion?
A
While sitting in a chair, you exert force on the chair, and the chair exerts the same amount of force back on you.
B
A basketball sitting on the basketball court doesn’t move until something pushes it.
C
You push a full shopping cart and an empty shopping cart. The empty shopping cart goes much faster than the full one.
D
You push your little brother on the swings, and he goes higher the harder you push him.
I would say A because Newton Law of motion is you pushing force and the object pushing force back on you
A basketball sitting on the basketball court doesn’t move until something pushes it. - this provides the best evidence for Newton’s First Law of Motion. Hence, option (B) is correct.
What is Newton’s First Law of Motion?According to Newton's first law of motion: Until and unless an external force occurs on a body, it is in a condition of rest or uniform motion in a straight line.
According to Newton's first law of motion, a body won't begin to move unless and until an outside force acts on it. When anything starts moving, it won't stop or vary its speed unless another force acts on it. The law of inertia is another name for the first law of motion.
Hence, a basketball sitting on the basketball court doesn’t move until something pushes it. This is an example of Newton’s First Law of Motion.

not cause planets in the solar system to pull on each other?
A. Gravitational
B. Weak nuclear
C. Strong nuclear
D. Electromagnetic
SUBMIT
Answer:
Electromagnetic
Explanation:
Just got it correct
The electromagnetic force of the four fundamental forces acts over very long distances but does not cause planets in the solar system to pull on each other. The correct option is D.
What is electromagnetic force?It is a type of force that occur between electrically charged particles. The electromagnetic force is the combination of all the electrical and magnetic forces generated from any charged particle.
The electromagnetic force is a long-range force that can either be attractive or repulsive.
As we know electromagnetic force is a long-range force but does
not cause planets in the solar system to pull on each other, therefore the correct answer is D.

Which resultant force is NOT possible if 50 N force and a 60 N force act concurrently?
Answer:
The options are not shown, so i will answer in a general way.
Suppose the case where the forces act in opposite directions, then we need to subtract the forces, and we know that the magnitude of the resultant force will be:
60N - 50N = 10N
Now, suppose the case where both forces act in the exact same direction, in that case, we will add the forces to get:
60N + 50N = 110N
Then the only range of forces that we can get in this system, are the forces such:
10N ≤ F ≤ 110N
Any resultant force outside that range is not possible in this situation.

Two men pull a 31 kg box with forces 11.6 N and 7.6 N in opposite directions. Find the resultant
acceleration of the box. (Hint: Find the net force first)
Answer:
0.13 m/s².
Explanation:
Mass (m) of box = 31 kg
Force 1 (F1) = 11.6 N
Force 2 (F2) = 7.6 N
Acceleration (a) of box =?
Next, we shall determine the net force acting on the box. This can be obtained as follow:
Force 1 (F1) = 11.6 N
Force 2 (F2) = 7.6 N
Net force (Fn) =?
Fn = F1 – F2
Fn = 11.6 – 7.6
Fn = 4 N
Thus, the net force acting on the box is 4 N.
Finally, we shall determine the acceleration of the box as follow:
Mass (m) of box = 31 kg
Net force (Fn) = 4 N
Acceleration (a) of box =?
Force (F) = mass (m) × acceleration (a)
4 = 31 × a
Divide both side by 31
a = 4 / 31
a = 0.13 m/s²
Therefore, the resultant acceleration of the box is 0.13 m/s².
A body at rest will remain at rest unless acted on by a(an) _____.

Answer:
A) I = 20 N s
, B) F = 7.92 N
Explanation:
A) The momentum is
I = F Δt
calculate
I = 50 0.40
I = 20 N s
B) The momentum is related to the change of the moment of the system
I = Δp
F Δt = m [tex]v_{f}[/tex] - m v₀
in this case we must assume that the initial velocity is very small, vo = 0
F = m v_{f} / Δt
calculate
F = 0.11 36 / 0.5
F = 7.92 N
