Discuss one component of your school's recycling system that could be automated and predict the economic impact.
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).

Who knew that so many forces acted on an object? Some make contact, others do not. Choose the forces that do not make contact with the object. There is more than one answer.
Question 1 options:
push
pull
motion
gravity
friction
Answer:
Gravity and electrostatic force
Explanation:
Gravity is a non contact force because the earth also attracts objects above its surface (not touching the earth). However, the further an object is from the centre of the earth, the weaker the force and the smaller its weight
The forces that do not make contact with the object are Gravity and Friction.
Gravity is a force exerted due to the pull of the Earth towards its center. It does not require direct contact as it attracts objects due to mass.
Friction is a force that opposes the motion of a body. It acts on the surface of a body in contact, not necessarily the body itself.
Therefore, Gravity and Frictions are the only two forces that do not make contact with the object out of the options.

Answer:
Pls Mark As Brainliest!!!!!!!!!
Explanation:
Gravity is More Than a Name
The Apple, the Moon, and the Inverse Square Law
Newton's Law of Universal Gravitation
Cavendish and the Value of G
The Value of g
As discussed earlier in Lesson 3, Isaac Newton compared the acceleration of the moon to the acceleration of objects on earth. Believing that gravitational forces were responsible for each, Newton was able to draw an important conclusion about the dependence of gravity upon distance. This comparison led him to conclude that the force of gravitational attraction between the Earth and other objects is inversely proportional to the distance separating the earth's center from the object's center. But distance is not the only variable affecting the magnitude of a gravitational force. Consider Newton's famous equation
Fnet = m • a
Newton knew that the force that caused the apple's acceleration (gravity) must be dependent upon the mass of the apple. And since the force acting to cause the apple's downward acceleration also causes the earth's upward acceleration (Newton's third law), that force must also depend upon the mass of the earth. So for Newton, the force of gravity acting between the earth and any other object is directly proportional to the mass of the earth, directly proportional to the mass of the object, and inversely proportional to the square of the distance that separates the centers of the earth and the object.

How do factors such as ocean currents, water temperature, and weather affect you in your daily life?
Answer:One way that the world’s ocean affects weather and climate is by playing an important role in keeping our planet warm.
Explanation:The majority of radiation from the Sun is absorbed by the ocean, particularly in tropical waters around the equator, where the ocean acts like a massive, heat-retaining solar panel. Land areas also absorb some sunlight, and the atmosphere helps to retain heat that would otherwise quickly radiate into space after sunset.

How does the sport curling relate to Newton’s Second Law of Motion?
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.
