Gas particles are spread farther apart from each other.
What is gas and its characteristics?Gas is a state of matter that has no fixed shape and no fixed volume.
Gases have a lower density than other states of matter, such as solids and liquids.
There is a great deal of empty space between particles, which have a lot of kinetic energy and aren't particularly attracted to one another.
The main characteristics of matter are:
(1) they are easy to compress,
(2) they expand to fill their containers, and
(3) they occupy far more space than the liquids or solids from which they form.
In a gas, particles are in continual straight-line motion.
The kinetic energy of the molecule is greater than the attractive force between them, thus, they are much farther apart and move freely of each other.

A car with a mass of 1,200 kg travels a distance of 150 m as it moves from
one stoplight to the next. At its fastest, the car travels at 22 m/s. What is its
kinetic energy at this point?
A. 290,400
B. 8,872 J
C. 580,800 J
D. 13,200 J
Answer:
A. 290,400
Explanation:
The kinetic energy of a car is 290,400J.
How to find Kinetic energy?Kinetic energy is directly proportional to the mass of the object and to the square of its velocity: K.E. = 1/2 m v2.
ke = 1/2mv^2
By using the formula, we get
= 1/2 * 1200 * 22^2
= 600 * 484
= 290,400 J
Kinetic energy is a form of energy that an object or a particle has by reason of its motion. If work, which transfers energy, is done on an object by applying a net force, the object speeds up and thereby gains kinetic energy.

The area of a triangle is 30 m². Using the equation A=12bh A = 1 2 b h , where b is base and h is height, solve for h if b = 3 m. Round to three decimal places, if necessary.
Answer:
20 metres
Explanation:
Given that the area of a triangle is 30 square metres (m²). Using the equation A = 1/2bh, this is the formula for the triangle.
where b is base and h is height
Given that b = 3 metres.
To calculate h, Substitute b and A into the equation
30 = 1/2 × 3 × h
3h = 60
h = 60/3
h = 20 m
Therefore, h is equal to 20 metres

Answer:
Acceleration
Explanation:
For example, if the acceleration is zero, then the velocity-time graph is a horizontal line (i.e., the slope is zero). If the acceleration is positive, then the line is an upward sloping line (i.e., the slope is positive).

What aspect of motion can you conclude is common among freely falling objects ?
Answer:
Free-fall is defined as the movement where the only force acting on an object is the gravitational force.
By the second Newton's law, we have that:
F = m*a
Where F = Force, m = mass, a = acceleration.
We can write this as:
a = F/m
And the gravitational force can be written as:
F = (G*M/r^2)*m
Where G is the gravitational constant, M is the mass of the Earth in this case, and r is the distance between both objects (the center of the Earth and the free-falling object)
As the radius of the Earth is really big, the term inside the parentheses is almost constant in the region of interest, then we can write:
G*M/r^2 ≈ g
And the gravitational force is:
F = g*m
And by the second Newton's law we had:
a = F/m = (g*m)/m = g
a = g
Then the acceleration does not depend on the mass of the object.
Then the thing that is common among the free-falling objects is the vertical acceleration.

Does the distance a person kicks a soccer ball
affect how well they will do on their math test?
Identify the independent and dependent
variable
Answer:
Independent variable: how far the soccer ball is kicked.
Dependent variable: how well the person does on their math test
Explanation:
The distance the ball is kicked is what the scientist can change. On the other hand, in this experiment, how well the person does on their test supposedly relies on how far the soccer ball is kicked.
Think and discuss: Why do you think the rate of temperature change does not stay constant over time? If possible, discuss your answer with your teacher and classmates.
Because the temperature of the place its contained in is constantly changing, for example, if you put a room temperature item in the fridge it will become cold, or whatever the temperature you set your fridge to.
Variation in the factors of climate leads to variable temperature around the world.
The rate of temperature change does not stay constant over time because of changes occur in the climatic factors. The climatic factors such as latitude, elevation, nearby water, ocean currents, topography, vegetation, and prevailing winds can't remain constant which leads to variable temperature in different regions of the world.
The temperature will remain the same if all the world has same environmental conditions so we can conclude that variation in the factors of climate leads to variable temperature around the world.

distance travelled by a train is 495 km in 4 hours 30 minutes, what is its speed in m/s?
Answer:
9.09m/s
Explanation:
Speed = Distance/Time
Distance = 495km
Time = 4 hr 30 min = 4 hr 1/2hr = 4.5 hr
Therefore, Speed = 495/4.5 = 110km/h
Now to convert km/h to m/s
110 x 1000/ 110 x 110
110 cancels out each other, we are now left with
1000/110 = 9.09m/s
A woman drives to her office 10 km away from her house at 9 am, and
reaches her office at 9:20 am. She stays in the office until 6 p.m, and
then returns home at 6:25 p.m. Which answer gives the correct
distance and displacement at 6:25 p.m.?
The displacement of the woman at 6:25 pm is zero (0) while her total distance at 6:25 pm is 20 km.
The given parameters;
distance between the woman's house and her office, d = 10 kmtime to reach her office = 20 minutestime to return to her house = 25 minutesDisplacement is defined as the change in the position of an object. It can be described as 'how far' an object is displaced from the initial position.
The first position of the woman, x₁ = 10 km to officeThe final position of the woman, x₂ = 10 km back homeThe woman's displacement = x₂ - x₁ = 10 km - 10 km = 0
Distance is the total path covered by an object during motion.
Total distance of the woman at 6:25 pm = 10 km + 10 km = 20 km
Thus, we can conclude that the displacement of the woman at 6:25 pm is zero (0) while her total distance at 6:25 pm is 20 km.

Percy threw a penny straight down off the Empire State building. The building is 354 m tall. If he threw the penny down such that it left his hand at 35 m/s, what is the acceleration of the penny? What will the velocity of the coin that Percy threw be when it hits the pavement?
Answer:
90.4 m/s
Explanation:
Take down to be positive. For objects in free fall, the acceleration is 9.8 m/s².
Given:
Δy = 354 m
v₀ = 35 m/s
a = 9.8 m/s²
Find:
v² = v₀² + 2aΔy
v² = (35 m/s)² + 2 (9.8 m/s²) (354 m)
v = 90.4 m/s

A boy standing on the bridge kicks a stone into the water below. He kicks the stone with a horizontal velocity of 6.59 m/s. It lands in the water 10.92 m away from the bridge. How high is the bridge?
The stone travels a horizontal distance of
x = (6.59 m/s) * t
after time t. For the stone to have covered 10.92 m, it would have traveled for
10.92 m = (6.59 m/s) * t
t = (10.92 m) / (6.59 m/s)
t ≈ 1.66 s
The stone's altitude at time t is
y = h - g/2 * t²
where g = 9.80 m/s² is the acceleration due to gravity, and h is the height of the bridge. The stone reaches the ground after about 1.66 s, so at that point y = 0 and we solve for h :
0 = h - 1/2 * (9.80 m/s²) * (1.66 s)²
h = 1/2 * (9.80 m/s²) * (1.66 s)²
h ≈ 13.5 m
Jan ran 4 miles north in 28 minutes. What was Jan's average velocity?
Answer:
3.83 m/s
Explanation:
Given that,
Distance covered by Jan, d = 4 miles
1 mile = 1609.34 m
4 miles = 6437.38 m
Time, t = 28 minutes = 1680 s
Jan's average speed,
v = d/t
[tex]v=\dfrac{6437.38\ \text{m}}{1680\ \text{s}}\\\\v=3.83\ \text{m/s}[/tex]
Hence, the average velocity of Jan is 3.83 m/s.

Explanation:
If a boat goes from 30 km/h to 50 km/h over the next 4 h, what is its acceleration? 30-50/4
Acceleration = (change in speed) divided by (time for the change)
Change in speed = (50 km/h)-(30 km/h)
Change in speed = 20 km/h
Acceleration = (20 km/h) / (4 h)
Acceleration = 5 km per hour-squared
