Where does gravity come from?
Answers
Answer:
gravity comes from the center of the Earth
Explanation:
Answer:
Earth's gravity comes from all its mass.
Explanation:
Earth's gravity comes from all its mass. All its mass makes a combined gravitational pull on all the mass in your body. That's what gives you weight. And if you were on a planet with less mass than Earth, you would weigh less than you do here.

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

The air currents across the continents would determine the distribution of the air.
What are air currents?Air currents across the continents are primarily driven by temperature differences and the rotation of the Earth. The warm air near the equator rises and flows towards the poles, while the cooler air near the poles sinks and flows towards the equator.
This creates large-scale circulation patterns known as Hadley cells, Ferrell cells, and Polar cells. These cells are responsible for the trade winds, westerlies, and easterlies, respectively. Additionally, there are also local winds caused by differences in terrain, such as sea breezes and valley breezes.

Answer:
1. 5 ft-lbs
2. 600 ft-lbs
The power of the first equation is 5 ft-lbs/sec and the power of the second equation is 10 ft-lbs/sec.
The power is a proportion of how rapidly work is being finished. It is the rate at which energy is moved or work is performed. The unit of force is watts (W), which is comparable to joules each second (J/s).
To compute power, we utilize the equation P = W/t, where P is power, W is work, and t is time. Work is how much energy moved when a power is applied over a distance, and it is estimated in foot-pounds (ft-lbs) or joules (J).
In the primary condition, the power is determined by partitioning 250 ft-lbs of work when it took to accomplish the work, which is 50 seconds. Thusly, the power is 5 ft-lbs/sec.
In the subsequent condition, we first proselyte 4 minutes to seconds, which is 240 seconds. Then, at that point, we partition 2400 ft-lbs of work by 240 seconds to get a force of 10 ft-lbs/sec.
The units for power are dependably ft-lbs/sec or J/s, and they address how much work done per unit time.

Kinetic energy converted to potential energy when the ball started moving down the ramp.
Potential energy converted to kinetic energy when the ball started moving down the ramp.
Energy was destroyed as the ball came to a stop.
Energy was created when the ball began moving down the ramp.
Answers
Answers:
Part One: Elastic Potential Energy
Part Two: Potential energy converted to kinetic energy when the ball started moving down the ramp.
Explanation:
Part One: The ball is not moving, therefore there is no Kinetic energy. The ball does not involve chemicals, so there is no Chemical Energy. By the process of elimination, you'll gather that there is potential energy to be had.
Part Two: Remember when we talked about the ball being still, and not moving? Well here's where it does. The potential energy has now turned into kinetic energy as it begins to roll down the ramp. The steeper the ramp the faster the kinetic energy will build.

Seagrasses are submerged flowering plants found in shallow marine waters, such as bays and lagoons and along the continental shelf in the Gulf of Mexico. A vital part of the marine ecosystem due to their productivity level, seagrasses provide food, habitat, and nursery areas for numerous vertebrate and invertebrate species. The vast biodiversity and sensitivity to changes in water quality inherent in seagrass communities makes seagrasses an important species to help determine the overall health of coastal ecosystems. Seagrasses perform numerous functions:
Stabilizing the sea bottom
Providing food and habitat for other marine organisms
Maintaining water quality
Supporting local economies
The work input = _____.
F i ÷ d i
F o ÷ d o
F o × d o
F i × d i
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

Processes operating in the Earth system take place on spatial scales varying from fractions of millimeters to thousands of kilometers, and on time scales that range from milliseconds to billions of years.
Examples of instantaneous - breathing; rotation of the Earth; earthquake
Examples of long term - making coal; plate tectonics
Cycles
The Earth system is characterized by numerous overlapping cycles in which matter is recycled over and over again. Cycles involve multiple spheres and systems interactions.
Examples of cycles: day and night; rock cycle; seasons

Discuss one component of your school's recycling system that could be automated and predict the economic impact.
Answers
One component of my school's recycling system that could be automated is the sorting of recyclables. Currently, the school relies on students and staff to sort recyclables into the appropriate bins, which can be time-consuming and may result in contamination if materials are not sorted properly.
Automating the sorting process with a machine or conveyor belt system could improve the efficiency and accuracy of the recycling system. It could also potentially reduce labor costs associated with manual sorting.
The economic impact of automating the sorting process would depend on the initial cost of the equipment and any associated installation or maintenance costs. However, over time, the improved efficiency and accuracy of the system could result in cost savings for the school. Additionally, the increased efficiency of the system could potentially lead to increased recycling rates, which could result in cost savings for waste disposal and potentially generate revenue through the sale of recycled materials.
Answer:
Our school has color coded virtual trash cans. For example, a trash can for only paper will only accept paper items, if the item put inside is not paper, it will litter it out and all students have cleaning duties throughout the week so even if you or someone litters you’ll probably have to clean it up at some point anyways. I honestly think it’s very cool. (i wish this was true smh).

Give three examples of properties of elements
Answers
Answer: Atomic number, Atomic Mass, Ionic radius
Explanation:
The three examples of properties of elements are Atomic Number, Melting Point, and Electronegativity are the properties of the element.
Atomic Number: The atomic number of an element is the number of protons found in the nucleus of an atom of that element. Each element has a unique atomic number.
Melting Point: The melting point of an element is the temperature at which it transitions from a solid state to a liquid state. Different elements have different melting points, which can vary widely.
Electronegativity: Electronegativity is a measure of an element's ability to attract electrons toward itself in a chemical bond. It is an important property in determining the nature of chemical bonding and the reactivity of elements. Elements with high electronegativity tend to attract electrons strongly.
Other properties include atomic mass, density, boiling point, reactivity, and many more, which contribute to the diverse behavior and characteristics of elements in the periodic table.
