Explain the Kinetic Theory of Matter
and use an example from everyday life
Answer:
The Kinetic Theory of Matter or KTM as i will call it, states that every object is made of many many small particles (humans are made of sextillions of atoms), and that they are constantly moving and bumping each other. The degree to which the particles move is determined by the amount of energy they have and their relationship to other particles.
An example would be Brownian Motion- the random movement of dust particles because of collisions with "air" molecules and how gases behave i.e. Boyle's, Charles', and Gay-Lussac's Laws.

Answer :Glaciers cause erosion by abrasion and
plucking
. The sediment deposited by glaciers is called till.
When a chunk of ice left behind by a receding glacier melts, the water stays in the kettle, forming a kettle lake.
Explanation:
I took the test
A) Glacier causes erosion by abrasion and plucking.
B) The sediment deposited by glaciers is called a moraine.
C) When a chunk of ice remained behind by a receding glacier melts, the water stays in the kettle, forming a kettle lake.
What are abrasion, plucking, and moraine?Abrasion contains the wear, polishing, and scratching produced in the bedrock by the thicker rock fragments brought by the ice, and in that way, grooves are formed.
Plucking generally takes place when advancing ice will push against fractured bedrock. Additional breaks can produce stress, while warmer temperatures and friction from glacier movement can bring the melting.
Moraine is the deposit of trawls of material fragmented by glaciers, which create mountain ranges because of their accumulation.
Glaciers are contacted by ice deposits due to continental glaciation. These forms develop with the glacier outwash and leave ice deposits. It generates a kettle lake when a large chunk of ice left a depression in the glacial drift when the ice melts a kettle-like hole is formed.

Describe all the ways that Newton’s Laws can apply in the game of football?
Answer:
Newton's Second Law of Motion states that a force on an object is equal to the mass of the object multiplied by its acceleration (F=ma). ... When the punter kicks the ball, his foot exerts a force on the ball. The football then exerts an equal amount of force in the opposite direction on the kicker's foot.
In football, the foot of a kicker applies force to the ball when he kicks it, as the force acting on a ball is equal to that ball's mass times its acceleration, so Newton's second law is applied here.
What is Newton's Second Law?The precise explanation of how a force can change a body's motion is given by Newton's second law. A body's momentum is said to vary at a rate equal to the force acting on it over time, both in magnitude and direction. A body's momentum is determined by its mass and velocity together.
According to Newton's Second Law of Motion, a force acting on an object is equal to that object's mass times its acceleration (F=ma). The punter's foot applies force to the ball when he kicks it. The kicker's foot is then subjected to an equivalent force from the football acting in the opposite direction.
Therefore, In football, the foot applies force to the ball when he kicks it, so Newton's second law is applied here.

How much work is done by a man if he moves a distance of 15m by applying the force of 20N? Find his power if he does the work in 2 seconds. (answer - 300 joule,150w)
Work= Distance × Force
15 metre × 20 N
300 Joule
Now ,
Power,
2 seconds = 300/2
150 watt
We know that
Unit of Work is Joule
Unit of Power is watt
So,
Work - 300 joule
Power= 150 watt

Explanation:
A student walks a distance of 3 km in 20 minutes calculate his average speed
Answer:
His average speed is 0.15 kilometer per minute or 2.5 meters per second.
Explanation:
average speed = distance/time
x = 3 km/20 minutes
x = 0.15
—
x = 3000 m/1200 s
x = 2.5
If a student walks a distance of 3 km in 20 minutes then the average speed of the student would be 9 kilometers per hour.
What is speed?The total distance covered by any object per unit of time is known as speed. It depends only on the magnitude of the moving object.
As given in the problem we have to calculate the average speed of the student if a student walks a distance of 3 km in 20 minutes.
The distance traveled in 20 min = 3 kilometers
The distance traveled in 60 min = 3 × 3
= 9 kilometers
Thus, If a student walks a distance of 3 km in 20 minutes then the average speed of the student would be 9 kilometers per hour.
