Answer: Differences: Solids have particles that are tightly packed and they form a pattern. In this case, they move and vibrate in place. On the other hand, liquid particles are close together but they have an irregular arrangement. The spaces between the particles allow them to move freely.
Explanation:
Particles in solids are arranged in a pattern and are closely packed. In this instance, they remain stationary and vibrate. However, despite being close together, liquid particle arrangements are asymmetrical. The particles can travel freely because of the voids between them and the similarity is both solid and liquid has some shape, but gas does the random movement in the container.
What is Particle motion in Solid, Liquid and Gas?In solid the particles are tightly packed with each other, so there will be no such movement by the particles it means that there the particles have very less kinetic energy. Solids have definite shape and size, and they are incompressible in nature, and they are tough and rigid as well.
In liquid the particles are lightly packed with each other due to which there is some movement in the particles it means that the particles have some kinetic energy. The liquids are compressible in nature. They do not have a specific shape, but they can take the shape of a container where it is filled.
Liquids are fluid in nature.
In gases, there is so much of distance between particles due to which the particles do random movement, and they have high kinetic energy. They do not have any shape and size, but they are highly compressible as compared to solid and liquid. They also take the shape of the container where they filled.

the sputnik 1 satellite orbited earth (mass=5.98 x 10^24 kg) in a circle of radius 6.96 x 10^6 m. what was its orbital velocity?
Answer:
v = 4.79 10³ m / s
Explanation:
For this exercise we will use the universal law of gravitation and Newton's second law
F = G M m / r²
where G is the gravitational constant, m the mass of the satellite, M the mass of the Earth, r the distance from the center of the planet to the satellite
F = m a
since the satellite has a circular path, the acceleration is centripetal
a = v² / r
we substitute
G M m / r² = m v² / r
G M / r = v²
We calculate
v² = 6.67 10⁻¹¹ 5.98 10²⁴ / 6.96 10⁶
v = √ (22.94 10⁶)
v = 4.79 10³ m / s

A student drops a 0.4kg ball from a height a of 49m above the ground. Neglect drag. Answer each of the following questions about the ball during the flight.
What is the magnitude of the net force on the ball?
What is the magnitude of the ball's acceleration?
How long does the ball take to hit the ground?
What is the ball's speed just before striking the ground?
• The only force acting on the ball, and thus the net force, is due to its own weight, with magnitude
w = m g = (0.4 kg) (9.8 m/s²) ≈ 3.9 N
pointing downward.
• The ball is in free fall, so its acceleration is g = 9.8 m/s² (also pointing downward).
• The ball is dropped from a height of 49 m, so its height y at time t is
y = 49 m - 1/2 g t ²
Set y = 0 and solve for t :
0 = 49 m - 1/2 g t ²
t ² = (98 m) / g
t = √((98 m) / g) = √(10) s ≈ 3.2 s
• The ball's velocity v at time t is
v = - g t
so that at the time found previously, the ball will have attained a velocity of
v = - g (3.2 s) ≈ -31 m/s
and thus a speed of about 31 m/s.

A train is traveling north. it goes 200 km /hr for 2.5 hours how far did the train go.
Explanation:
The formula for finding distance is: speed × time
We must multiply:
200Km/h × 2.5 hours
This gives you 500 Km.
Remember: the formula to work out the distance - speed x time.
If the train speed is 200 km/h, it travels 200 km/h.
Now, we must multiply 200 by 2.5:
200 x 2.5 = 500
Our answer is 500 Kilometers.

The element selenium (Se) bonds with chlorine (Cl) to make the formula SeCl2 Chlorine is more electronegative than selenium. What is the name of this molecular compound?
Answer:
Selenium dichloride
Explanation:
Selenium (Se) and Chlorine (Cl) are both elements capable of combining together to form a compound with the chemical formula; SeCl2. Since the chlorine atom is more electronegative than selenium atom, the chlorine pulls more electrons towards itself to form an IONIC bond.
The SeCl2 compound formed is called Selenium dichloride as two atoms of Chlorine are needed to combine with one atom of Selenium to form the compound.
The name of the molecular compound is selenium dichloride (SeCl2).
• Due to sharing of electrons between selenium and chlorine, Selenium dichloride is considered as covalent compound.
• Both the elements are non-metals, and thus, would give rise to covalent bond.
• Selenium is the least electronegative element of the two, so it is written first.
• After that the more electronegative element is written, and then addition of suffix is done, that is, -ide.
• If atoms of an element is more than one, then prefixes are supplemented that is mono for 1 atom, di for two atoms, and tri for three atoms.
Thus, the name of the molecular compound is selenium dichloride.

Kristina demonstrates a toy for her younger brother. The steps to operate the toy are listed below. Step 1. Push the toy down. Step 2. A spring compresses. Step 3. Release the toy. Step 4. The toy jumps into the air. Which best describes Step 4? Elastic potential energy changes to gravitational potential energy. Gravitational potential energy changes to elastic potential energy. Kristina does work to increase the gravitational potential energy. Kristina does work to increase the elastic potential energy.
Answer:
It's A
Elastic potential energy changes to gravitational potential energy
Explanation:
Step 4 can be described as "elastic potential energy changes to gravitational potential energy." The correct option is A.
What is the difference between potential energy and gravitational potential energy?Potential energy is the energy stored in an object due to its position, configuration, or state. It is a scalar quantity that describes the amount of energy that an object possesses by virtue of its position or configuration.
Gravitational potential energy, on the other hand, is a specific type of potential energy that is associated with an object's position in a gravitational field. It is defined as the amount of work that must be done to move an object from its current position to a reference position where its gravitational potential energy is zero, typically at an infinite distance away from the gravitational source.
The gravitational potential energy of an object depends on its mass, its height above a reference level, and the strength of the gravitational field in which it is located. The formula for gravitational potential energy is:
PE_grav = mgh
Where PE_grav is the gravitational potential energy, m is the mass of the object, g is the acceleration due to gravity, and h is the height of the object above the reference level.
So, potential energy is a general term for any type of energy stored in an object, while gravitational potential energy is a specific type of potential energy that is associated with an object's position in a gravitational field.
Here in the Question,
When the toy is pushed down in Step 1, energy is stored in the spring as elastic potential energy. As the spring compresses in Step 2, this potential energy is increased.
When the toy is released in Step 3, the compressed spring rapidly expands and releases the stored elastic potential energy. This energy is then converted into kinetic energy as the toy jumps into the air.
As the toy jumps into the air, its height increases and it gains gravitational potential energy. This energy is due to the toy's position in a gravitational field, and it is stored in the toy's interaction with Earth's gravitational pull.
Therefore, the energy transformation that occurs in Step 4 is from elastic potential energy to gravitational potential energy.

A closely wound search coil has an area of 3.13 cm2, 135 turns, and a resistance of 61.1 Ω. It is connected to a charge-measuring instrument whose resistance is 44.4 Ω. When the coil is rotated quickly from a position parallel to a uniform magnetic field to one perpendicular to the field, the instrument indicates a charge of 3.44×10−5 C . What is the magnitude of the magnetic field?
Answer:
Explanation:
Let the magnitude of magnetic field be B .
flux passing through the coil's = area of coil x field x no of turns
Φ = 3.13 x 10⁻⁴ x B x 135 = 422.55 x 10⁻⁴ B .
emf induced = dΦ / dt , Φ is magnetic flux.
current i = dΦ /dt x 1/R
charge through the coil = ∫ i dt
= ∫ dΦ /dt x 1/R dt
= 1 / R ∫ dΦ
= Φ / R
Total resistance R = 61.1 + 44.4 = 105.5 ohm .
3.44 x 10⁻⁵ = 422.55 x 10⁻⁴ B / 105.5
B = 3.44 x 10⁻⁵ x 105.5 / 422.55 x 10⁻⁴
= .86 x 10⁻¹
= .086 T .
A top sprinter reached his maximum instantaneous velocity of 12.28 meters per second 7.17 seconds after leaving the blocks. Calculate his acceleration. All key steps must be shown.
I am very confused will you please help me!!
Answer:
Here we will assume two things.
His acceleration is constant until he reaches his maximum velocity and then he stops accelerating.
When he leaves the blocks, his velocity is "zero", meaning that the initial velocity is zero.
Then:
For the acceleration of the sprinter we will have a constant, A:
a(t) = A.
for the velocity we need to integrate over time, we will get
v(t) = A*t + v0
Where v0 is a constant of integration, and this is the initial velocity, as we already said, this will be zero, so the velocity equation is:
v(t) = A*t
We know that at t = 7.17 seconds, his velocity is 12.28m/s
then:
v(7.17s) = 12.28m/s = A*7.17s
12.28m/s/7.17s = 1.71 m/s^2 = A.
The acceleration is: 1.71 m/s^2 for 0 < t < 7.17s
0 m/s^2 for 7.17s < t.
This is because that was his maximum velocity, then after that time he can not accelerate more.
A certain body is thrown at an angle of 30° to the horizontal with a speed of 20m/s. What is the time the body takes to reach the maximum height?
Answer: here is my answer

Select the correct answer. The formula for calculating power is work divided by time (power = work ÷ time). What are two ways of stating the same relationship? work = power ÷ time work = power × time time = work ÷ power time = work × power power = work × time
Answer:
work = power × time
time = work ÷ power
Explanation:
Power is defined as the rate at which work is done.
It is mathematically expressed as;
Power = [tex]\frac{work}{time}[/tex]
From this expression, if we cross multiply, we get;
work = power x time
Also, if we divide both sides by power, we get;
time = work ÷ power
Joseph remembers reading that for a particular pressure, P1, there is a maximum height to which a fluid can rise. He reasons that in this case the pressure (P2) must drop to zero so that the water can no longer flow to increased heights. He decides to check if the simulation can be made to demonstrate such conditions. He decides to make A2 as small as possible in the simulation (2.2 cm2) so that he increases the speed of the fluid in tube 2 as high as is possible (he decides to do this after examining the continuity equation). He then calculates the height of the fluid under these conditions where the pressure would fall to zero so that the fluid could no longer be made to flow under the conditions set up in the simulation. He then runs the simulation under the largest Δy allowed to check his calculation. What does Joseph calculate for the maximum height?
Answer:
h = P₁ / 9800
Explanation:
This is a fluid mechanics problem, let's write the Bernoulli equation at two points, the subscript 1 for the lowest point and the subscript of 2 for the point with the highest height.
P₁ + ½ ρ v₁² + ρ g y₁ = P₂ + ½ ρ v₂² + ρ g y₂
at the highest point P₂ = 0 and v₂ = 0,
P1 + ½ ρ v12 = ρ g (y₂ -y₁)
we use the continuity equation for the velocity at the lowest point
A₁ v₁ = A₂ v₂
Since the velocity at the highest point is zero, this implies from the equation that the velocity at the lowest point is also zero. In the no-flow condition
P₁ = ρ g (y₂ -y₁)
h = y₂-y₁
h = P₁ /ρ g
the density of water is ρ = 1000 kg / m³ and g = 9.8 m/s², we substitute
h = P₁ / 9800
Let's do a calculation, suppose that P₁ = 1 10⁵ Pa
h = 1 10⁵ / 9800
h = 10.2 m
