19. The particles in an object move very quickly and are spread apart. Then they move slower and get slower and get closer together but do not form regular and organized patterns. What change of state occured? How do you know?
Answer:
The transformation went from a gas to a solid which is a Deposition
Explanation:
Deposition is the phase transition in which gas transforms into solid without passing through the liquid phase. Deposition is a thermodynamic process. The reverse of deposition is sublimation and hence sometimes deposition is called desublimation.
The change of state that occurred was that the object went from gas to solid in a process of Deposition.
The properties of gas and solid:
Particles in gas move very quickly which leads to them being spread apart Particles in solids are quite slow and so are close togetherBased on the properties of the object before and after the change, we can infer that the object went from gas directly to solid. This process is called a deposition.
In conclusion, a deposition occurred with gas changing directly to solid.

2. Tomas is hanging from a tree limb, that is inclined at a 65° angle. The force
of gravity on Tomas is 57 N. Find the net force acting on Tomas.
Answer:
57 N
Explanation:
Were are told that the force
of gravity on Tomas is 57 N.
And it acts at an inclined angle of 65°
Thus;
The vertical component of the velocity is; F_y = 57 sin 65
While the horizontal component is;
F_x = 57 cos 65
Thus;
F_y = 51.66 N
F_x = 24.09 N
The net force will be;
F_net = √((F_y)² + (F_x)²)
F_net = √(51.66² + 24.09²)
F_net = √3249.0837
F_net = 57 N

Explain how the Sun's gravitational force affects Earth even though the Sun is 93 million miles away.
Answer:
Perfect distance away makes it suitable for life
Explanation:
The Sun's gravitational pull helps to control tides on earth and also to keep the earth in a curvilinear motion.
What is gravity?Gravity, or gravitation, is a natural phenomenon in which all entities with mass or energy are drawn to one another, including planets, stars, galaxies, and even light.
The gravitational pull of the sun continuously pulls the earth towards it, although because of the fast movement of the earth we never reach towards the sun instead we revolve around it.
Despite the fact that the sun's gravitational pull is neutralised by the movement of the earth in a curve, there is still some gravitational pull that exists which helps to control the tides on earth.
Thus, the Sun's gravitational pull helps to control tides on earth and also to keep the earth in a curvilinear motion.

A toy car, initially travelling in a straight line at 30.0 cm/s, slows down with a constant linear acceleration of 3.0 cm/s2. How much time passes before the toy car comes to a halt?
Answer:
10s
Explanation:
Given parameters:
Initial velocity = 30cm/s
Acceleration = 3cm/s²
Unknown:
Time it takes for the car to come to rest = ?
Solution:
To solve this problem, we apply the right motion equation;
Our final velocity - 0
So;
V = U + at
Since the car is slowing down, it will have a negative acceleration
Insert the parameters and solve;
0 = 30 + (-3) x t
-30 = -t
t = 10s
A trebuchet at ground levels throws a boulder with an initial velocity of 25 m/s at 30 degrees.
What was the magnitude of the final velocity of the boulder before it hit the ground?
a
30 m/s
b
10 m/s
C С
25 m/s
ОООООО
d
20 m/s
e
27.5 m/s
12.5 m/s
Answer:
The correct option is;
C. 25 m/s
Explanation:
The initial velocity with which the boulder was thrown = 25 m/s
The path in which the boulder projectile moves = 30°
For projectile motion, we have;
The time it takes the boulder to hit the ground is given by the following equation;
y = y₀ + v₀·sin(θ₀)t -¹/₂·g·t²
Where;
y = The height of the boulder
y₀ = The initial height of the boulder = 0
g = The acceleration due to gravity = 9.81 m/s²
When the boulder touches the ground again, the value of y = 0. therefore, we have;
0 = 0 + 25 × sin(30)t -¹/₂ × 9.81 × t²= 12.5·t - 4.905·t²
From which we have, t = 0 or t ≈ 2.55 s
At t = 2.55 s The vertical velocity = v₀sin(θ₀) - g·t = 25 × 0.5 - 9.81×2.55 = -12.5 m/s
The vertical velocity, [tex]v_y[/tex] = -12.5 m/s
The horizontal velocity, vₓ = v₀·cos(θ₀) = 25×cos(30) ≈ 21.65 m/s
The magnitude of the resultant velocity before, the boulder hits the ground is given as follows
[tex]\left | v \right |[/tex] = √((vₓ)² + ([tex]v_y[/tex])²) = √(12.5² + 21.65²) = √625 = 25
The magnitude of the resultant velocity before, the boulder hits the ground is 25 m/c

please follow me...A ball is thrown straight up from the ground. Where will the ball have its lowest velocity
Explanation:
i think it will be on the ground
Can you pls answer the 2 questions
Answer:
1) False, since constant speed means constant velocity, but with constant direction as well. Velocity is speed with direction. When you move in a circle, there are boundaries which means that a constant moving speed will cause the object to veer(move in different directions) to maintain movement, If it doesn't veer, the object will deflect(rebound) off the surface due to friction, and impact force or depending on its physical bond of malleability or density.
2a) Create position vectors by drawing a ray from the center(origin) of the circle to each of your desired points, it's magnitude will be the radius(how convenient). Both of these vectors go from the center of the circle to the position on the circle. In general, the distance from the origin to a point is called the radius vector.

Which object has a net force of –5 N down?
Answer:
y
Explanation:
i did it
The object in image [x] has a net force of -5 Newtons in the vertical direction.
What is force?In order to move a body of mass (m) with an acceleration of 'a' m/s², a force of magnitude equal to the product of body's mass and the required acceleration is needed. Mathematically -
F = ma
It is a vector quantity. In a three dimensional coordinate, the force vector can be resolved as -
[F] = F[x] a[x] + F[y] a[y] + F[z] a[z]
[F] = m {A[x] a[x] + A[y] a[y] + A[z] a[z]}
We have free - body diagrams as shown in the image.
If we observe image [x], we can easy calculate that -
The force along the horizontal F[h] = 15 - 15 = 0
The force along the vertical F[v] = 20 - 25 = - 5 Newtons
Therefore, the object in image [x] has a net force of -5 Newtons in the vertical direction.

Why are systems in Dynamic Equilibrium stable?
Answer:
Dynamic Equilibrium are stable because there is an equal rate of transition between reactants and products, or between the forward and the reverse process, in a back and forth manner, such that the net change of the concentration or system is zero, and therefore, there are no excess force factor, tending to create a different outcome
Explanation:
Dynamic equilibrium, in physics and in chemistry, is the equilibrium experienced by a system that undergoes change, where however, both the forward and the reverse effect of the change are taking place.
how is the atmospheric pressure detected
Answer:
The air around you has weight, and it presses against everything it touches. That pressure is called atmospheric pressure, or air pressure. It is the force exerted on a surface by the air above it as gravity pulls it to Earth.
Atmospheric pressure is commonly measured with a barometer. In a barometer, a column of mercury in a glass tube rises or falls as the weight of the atmosphere changes. Meteorologists describe the atmospheric pressure by how high the mercury rises.
An atmosphere (atm) is a unit of measurement equal to the average air pressure at sea level at a temperature of 15 degrees Celsius (59 degrees Fahrenheit). One atmosphere is 1,013 millibars, or 760 millimeters (29.92 inches) of mercury.
Atmospheric pressure drops as altitude increases. The atmospheric pressure on Denali, Alaska, is about half that of Honolulu, Hawai'i. Honolulu is a city at sea level. Denali, also known as Mount McKinley, is the highest peak in North America.
