The breakdown or dissolution of rocks and minerals on the Earth's surface is referred to as weathering. Agents of weathering include water, ice, acids, salts, plants, animals, and variations in temperature.
The effects of weathering and erosion cannot be resisted by any rock on Earth due to its softness. These processes combined to carve famous sites like Arizona's Grand Canyon.

All living things are closely related to their environment. Any change in one part of an environment causes a stimulus.
What is an Environment?All living or non-living objects that occur naturally, or in this example, without the use of artificial means, are included in the natural surroundings or natural world. The phrase is most frequently used with reference to Earth or certain regions of it.
An environment encompasses all that surrounds us, including both living and dead objects like water, soil, plants, and animals that can adapt to their environment. The gift of nature is what sustains life on Earth.
Environment can be summed up as the effects of every one of the living or non-living things that have an impact on human life. Non-living or abiotic elements include water, land, sunshine, rocks, and air, whereas all live or biotic components are animals, plants, forests, fisheries, and birds.
Thus, all living things are closely related to their environment. Any change in one part of an environment causes a stimulus.

How do you know that Earth is affected by the gravitational pull of the sun ? Explain how you would be affected if you were able to safely move farther and farther away from Earth . Support your ideas
Answer:
The Sun's gravity pulls on the planets, just as Earth's gravity pulls down anything that is not held up by some other force and keeps you and me on the ground.
Explanation: Newton realized that the reason the planets orbit the Sun is related to why objects fall to Earth when we drop them. I am so sorry if I get this wrong, I'm in 5th grade! ♥
The Sun provides rotational motion to Earth by gravitational pull and if we get farther and farther, we will experience decreased gravitational force.
The Earth is continuously orbiting around the Sun, that is why we are experiencing the day and night everyday. And this orbiting is caused by the gravitational full by Sun on Earth, which is given as,
[tex]F = \dfrac{G \times M \times M'}{R^{2}}[/tex]
Here, G is the universal gravitational constant, M is the mass of Earth and M' is the mass of Sun. And R is the distance between the Earth and Sun.
If we suppose to move farther and farther away from the Earth then the strength of gravitational pull by Earth will decrease with the increasing distance. Because the gravitational pull is inversely proportional to square of distance.
Thus, we can conclude that the Sun provides rotational motion to Earth by gravitational pull and if we get farther and farther, we will experience decreased gravitational force.

If a storm is 7.5 kilometers away, how much time is expected between observations of lightning and thunder?
Answer:
≈ 22 seconds
Explanation:
7,5 km = 7500 m
Speed of light 300 000 000 m/s (for lightning)
Speed of sound 343 m/s (for thunder)
time = distance / speed
lightning time = 7500 m / 300 000 000 m/s = 0.000025 s
thunder time = 7500 m / 343 m/s ≈ 22 s
thunder time - lightning time = 22 s - 0.000025 s ≈ 22 s

An object spins with an angular momentum of 8.9 kg⋅m2 /s. A torque on the object causes it to slow to a stop in 5.2 s. What was the angular impulse on the object? What was the average torque on it? Analyze and Sketch the Problem
List Knowns and Unknowns Knowns Unknowns Li = ____________________ Lf = ________________ _____________ = ? ∆t = _________________ _____________ = ? SOLVE FOR THE UNKNOWNS a. Determine the angular impulse from the change in angular momentum b. Apply the impulse-momentum theorem to determine the Torque EVALUATE THE ANSWER Is the unit of torque correct? ______________________________________________________________ Is the magnitude of the torque realistic? _____________________________________________________
Answer:
Explanation:
Li = 8.9 kg m² /s , Lf = 0
Time = Δt = 5.2 s
Angular impulse = change in angular momentum = Li - Lf
= 8.9 - 0 = 8.9 kg.m²/s .
Average torque = angular impulse / time
= 8.9 / 5.2 = 1.711 kg m² / s²
Li = 8.9 kg m² /s , Lf = 0
Δt = 5.2 s
unit of torque = force x distance = mass x acceleration x distance
= kg . m /s² x m
= kg m² / s²
Why does the chord of an electric heater not glow while the heating element does
Answer:
The heating element of the heater is made up of alloy which has very high resistance so when current flows through the heating element, it becomes too hot and glows red. But the resistance of cord which is usually of copper or aluminum is very low so it does not glow.
A spring with k = 33.5 N/m has a
1.20 kg mass attached. It is pulled
0.120 m and released. How much
mechanical energy does it have?
(Unit = J)
Answer:
M.E = 0.241 Joules.
Explanation:
Given the following data;
Spring constant, k = 33.5 N/m
Extension, e = 0.12m
Mass = 1.20kg
To find the mechanical energy (M.E);
Mathematically, mechanical energy is given by this formula;
M.E = ½ke²
Where;
k is the constant of elasticity (spring constant). e is the extension of the string.Substituting into the equation, we have;
M.E = ½*33.5*0.12²
M.E = ½*33.5*0.0144
M.E = 0.4824/2
M.E = 0.241 Joules.

example of unlile parallel forces
Answer:
Explanation:
In mechanical engineering, a parallel force system is a situation in which two forces of equal magnitude act in the same direction within the same plane, with the counter force in the middle. An example of this is a see saw.
Forces which are parallel and acting a similar way are called like parallel forces. Like Parallel forces are the forces that are parallel to each other and have the same direction. Unlike parallel forces are the forces that parallel yet have directions inverse to each other.
when the parallel force system is a situation in which two forces of equal magnitude act in the same direction within the same plane, Two forces that are parallel can either be in the same direction or in opposite directions.

Ana kicks a stationary 0.2 kg soccer ball. The ball leaves her foot at a speed of 20 m/s.
a. What impulse was delivered to the ball?
b. The ball experiences 40N of force during the kick. How long were the ball and
foot in contact?
Answer:
a. 24 kg m/s
b. 3/5s
Explanation:
a.impulse is the change in momentum so at first the momentum is zero because the ball was at rest and the final momentum is 1.2kg*20m/s=24 kg m/s
so the impulse would be (24-0) kg m/s=24 kg m/s
b. so the impulse equation is impulse is force *delts time
so 24 kg m/s=40N*t
t=24 kg m/s /40N=3/5 s

Kindly check explanation
Explanation:
Our environment consists of various materials, structures and resources which are so naturally interrelated, the survival of a certain species depends on the wellbeing of the other. This could be buttressed from the definition of environment which simply means the entirety of factors, naturally occurring phenomenon around us. The pollution of the air affects the oxygen we breathe in due to contamination ad thus affects the health of those who Live within the affected area. Change in climatic condition, vegetation and other phenomenon will always affect the environment since the environment itself isn't just humans being but the entirety of conditions both natural occurring and others which keeps the live and the world in existence.
