3. Using the Kinetic Molecular Theory of Matter explain what is happening to the liquid in a thermometer when it measures something that is hot. What about when it measures something that is cold
Answers
According to the Kinetic Molecular Theory of Matter, the temperature of a substance is directly proportional to the average kinetic energy of the particles that make up the substance.
When a liquid thermometer measures something that is hot, the particles in the hot substance have a higher kinetic energy than the particles in the liquid thermometer. This causes the particles in the liquid thermometer to gain kinetic energy and move faster. As they move faster, they take up more space, causing the liquid to expand and rise in the thermometer.
On the other hand, when a liquid thermometer measures something that is cold, the particles in the cold substance have a lower kinetic energy than the particles in the liquid thermometer. This causes the particles in the liquid thermometer to lose kinetic energy and move slower. As they move slower, they take up less space, causing the liquid to contract and fall in the thermometer.
Therefore, when a liquid thermometer measures something that is hot, the liquid expands and rises in the thermometer, and when it measures something that is cold, the liquid contracts and falls in the thermometer.

The velocity of the vehicle is equal to 406.5 m/s. The velocity in Km/hr is 1463.4 Km/hr.
What is the velocity?Velocity can be demonstrated as a vector measurement of the direction of the object and the rate of motion of an object. The velocity of an object can be described as the change in the body's position w.r.t. time.
Velocity can be expressed as a vector quantity as it consists of magnitude as well as direction. A mathematical formula common and simplest way to find velocity.
v = d / t
Where v is the velocity, d is the distance covered and t is the time taken by the body.
The S.I. unit for velocity can be represented as m/s and can be expressed in terms of miles per hour (mph), and kilometers per hour (kph).
Given, the distance traveled by the vehicle, d = 100 m
The time taken by vehicle = 0.246 sec
The velocity of the vehicle, v = 100/0.246 = 406.5 m/s
We know that 1km = 1000m then 1 m = 10⁻³ Km
1 hour = 60 ×60 = 3600 s
1s = 1/3600 hr
Therefore, velocity, \(\displaystyle v = 406.5 \times \frac{3600}{1000} Km/hr\)
v = 1463.4 Km/hr

Velocity = Distance / Time = 100 m / 0.246 s = 406.50 m/s
To convert m/s to km/hr, we need to multiply the velocity by 3.6:
Velocity in km/hr = Velocity in m/s x 3.6 = 406.50 m/s x 3.6 = 1463.80 km/hr
The steps I took to convert from m/s to km/hr were to multiply the velocity in m/s by 3.6, which is the conversion factor between meters per second and kilometers per hour.

Explanation:
Although two identical objects may have the same mass and the same weight (meaning that the force of gravity is the same for both), they may not fall to Earth at the same rate. This is because of air resistance. Any object that is falling has friction, or resistance, from the air. The larger the object, the more resistance it has as it falls.
Get two identical pieces of paper. Crumple one up into a ball, but leave the other one a flat sheet. Drop both pieces of paper off a high place at the same time. What happens? Which falls faster? Record your observations and make a conclusion, using the terms “mass,” “weight,” “force,” “resistance,” and “gravity.”
MUST BE AT LEAST 4 sentences and include the terms weight, force, resistance, and gravity.
Answers
Answer:
the paper ball falls faster and the unfolded paper falls at a slower rate
Explanation:
this is because gravity is pulling both objects down to the ground and hence they are falling. Both objects have the same mass and weight but the resultant force of the paper ball is smaller than that of the unfolded paper. The unfolded paper has a larger surface area and so a larger force is acted upon it, meaning there is more air resistance. This shows that the paper ball falls faster than the unfolded paper.
The air resistance acting on the crumpled ball will be less and hence it will fall faster.
What is Air resistance?
Air resistance describes the forces that are in opposition to the relative motion of an object as it passes through the air. The larger the object, the more resistance it has as it falls.
Mathematically, we can write it as -
F = \(\frac{1}{2} C_{D}\) × ρv²A
Given are two identical pieces of paper such that one is crumpled up into a ball and the other one is left as flat sheet.
Now, as you throw both, the crumpled up ball and the flat sheet, the crumpled up ball will fall faster. The main reason behind this is that the total surface area of the crumpled ball in contact with the air is less than compared to that of the flat sheet. Air resistance on the crumpled ball with surface are in contact [say A(c)] can be written as -
F[1] = \(\frac{1}{2} C_{D}\) × ρv²A(c)
And that on the flat sheet with area of contact with the air [say A(f)] can be written as -
F[2] = \(\frac{1}{2} C_{D}\) × ρv²A(f)
Now as A(f) > A(c), therefore F[2] > F[1]
Therefore, the air resistance acting on the crumpled ball will be less and hence it will fall faster.

How does the sport curling relate to Newton’s Second Law of Motion?
Answers
Curling is a sport in which players slide stones across a distance of ice toward a target area. The purpose is to accumulate the loftiest score for a game by making monuments rest closest to the center of the target at the end of each side. There are two brigades. Each platoon is trying to keep the other platoon's monuments down from the target by knocking their monuments out of the way.
Newton's Second Law " The acceleration of an object is directly commensurable to the net force acting on it and is equally commensurable to its mass. The direction of the acceleration is in the same direction as the net force acting on an object." This relates to the formula F = ma. The mass of the determinedness monuments in curling is 38 to 44 pounds or 17.3 to 20 kg. The thing of the sweepers is to control the acceleration of the gravestone by reducing disunion on the ice, which affects the force with which the gravestone is suitable to impact the other monuments.

Second law-
Newtons second law occurs during curling when the delivery man, such as Glenn Howard, applies force to the stone pushing down the lane to the target while friction pulls it back the other way to a slow stop. The mass of the stone is 40lbs and the net force of everything on item will give you its slowly decreasing acceleration. Otherwise known as, F=mA.
Third law-
This law can be exerted in the sport of curling when the force behind a stone being delivered is transferred into another stone that is at rest, where the energy and force of one moving object is transferred to another. This almost completely stops the original stone, and gives some speed to the stone(s) it collides with.
