Why is it important to track our carbon and ecological footprint?
Answers
Answer: I got you Fam
Explanation:
it is one competing demand for biologically productive space
Answer:
The carbon footprint is a very important means to understand the impact of a person's behavior on global warming. This is why someone who effectively wants to contribute to stopping global warming, at least on an individual scale, needs to measure and keep track of their personal carbon footprint.
Why is it important to track your ecological footprint?
The Ecological Footprint is a simple metric. It is also uniquely comprehensive. Not only does it measure humanity's demand on our planet's ecosystems, but it is also key to understanding the inter-related pressures of climate change on the natural ecosystems on which humanity depends.
Why is knowing your carbon ecological footprint important?
Knowing your personal or organisational carbon footprint is useful for the following reasons: it enables you to identify and reduce GG emissions, it allows corporations to publish their environmental performance statistics, it can be used as information to raise awareness of environmental costs.

Justin and Oscar each hit a baseball with a bat. The baseballs have the same mass, but the ball Justin hits has a greater acceleration. What might be the reason for the greater acceleration of Justin's baseball?
Answers
The acceleration is different in both cases because, the force applied is different. Acceleration is force divided by mass of the object. Thus, Justin had greater force than Oscar.
What is force ?Force is an external agent acting on body to change its motion or deform it. There are various kinds of forces such as frictional force, gravitational force, nuclear force etc.
According to Newton's second law of motion, the force acting on an object is the product of its mass and acceleration.
Thus, F = ma
Hence, as the force increases the body is accelerated more.
With the same mass for the two balls, the force used to hit it was different and thus, the acceleration differs in both cases. Therefore, Justin has the greater force.

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.

Answers
Answer:Gravity is the force among the options listed that has not directly changed Earth's surface.
Explanation:
Gravity is a fundamental force that acts on all objects with mass, including the Earth itself, but it does not cause changes or modifications to the Earth's surface features. Instead, gravity influences the movement of materials and the shape of the Earth's surface by exerting a pulling force on objects. On the other hand, folding, erosion, and weathering are all processes that directly contribute to shaping

A cylindrical tube of length 27.75 cm and radius 2.00 cm is filled with argon gas. The empty tube weighs 188.25 g. The tube filled with argon weighs 188.87 g. Calculate the density. formula =
Answers
Answer:
Explanation:
that should help
Density is mass per unit of volume. The density of argon is 1.778 × 10⁻³ gm/cm³.
How are the density, volume, and mass of a substance related?Suppose that a finite amount of substance is there having its properties as:
mass of substance = m kgdensity of substance = d kg/m³the volume of that substance = v m³Then, they are related as:
d = m/v
The volume of the tube = π × r² × h
= π × (2cm)² × 27.75 cm
= 348.716 cm³
Mass of Argon = Mass when tube is filled - Mass when tube is empty
= 188.87 g - 188.25 g
= 0.62 g
Now, the density of the gas can be written as,
Density = Mass / Volume
= 0.62g / 348.716 cm³
= 1.778 × 10⁻³ gm/cm³
Hence, the density of argon is 1.778 × 10⁻³ gm/cm³.

Answers
Here, we are required to determine which procedure could be used to demonstrate that matter is conserved during a chemical change or reaction.
The Correct answer is option A.
First, a chemical change is one in which a chemical compound is transformed into one or more chemical substances and consequently, the resulting compounds have different chemical properties as their atoms are arranged differently.
From the definition above, it is evident option A where an acid and a base are reacted together to form water and salt is an example of chemical change and obeys the law of conservation of matter.
This is so because, upon first measuring the mass of the acid and base separately and then measuring the mass of the resulting salt and water.
The mass in both instances is constant.

Answers
The work input = Fi × di
How to solve for work input?To solve for work input, you need to know the force acting on an object and the distance it moves in the direction of the force. Work input is defined as the product of force and distance, given by the formula:
Work Input = Force × Distance × cosθ
Where θ is the angle between the force vector and the direction of motion. If the force is applied in the direction of motion, then θ = 0 and cosθ = 1, so the formula simplifies to:
Work Input = Force × Distance
For example, if you are pushing a box with a force of 50 newtons over a distance of 10 meters, the work input would be:
Work Input = 50 N × 10 m × cos(0°) = 500 Joules
