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).

The potential energy of the cart loaded with a brick and that is pulled at constant sped along an inclined plane to a height of 0.45 meters, is 13.24 J.  

At the height of the seat-top, the potential energy is given by:

\( E_{p} = mgh \)

Where:

g: is the acceleration due to gravity = 9.81 m/s²

m: is the mass of the loaded cart = 3.0 kg

h: is the height = 0.45 m

Hence, the potential energy is:

\( E_{p} = mgh = 3.0 kg*9.81 m/s^{2}*0.45 m = 13.24 J \)

Therefore, the potential energy of the loaded cart at the height of the seat-top is 13.24 J.

Answer:

The estimated braking force needed to stop the lorry is zero, based on the given information and calculations. However, it's important to note that this result is likely not accurate, as some force is required to stop a moving object. It's possible that additional information or calculations are needed to obtain a more realistic estimate of the braking force.

Explanation:

To estimate the braking force needed to stop the lorry, we can use Newton's second law of motion, which states that force (F) is equal to mass (m) multiplied by acceleration (a).

In this case, the lorry decelerates uniformly, so the acceleration is constant. The initial velocity is assumed to be zero since the lorry comes to a stop. The final velocity is also zero. Therefore, we can use the equation:

Final velocity squared (vf^2) = Initial velocity squared (vi^2) + 2 * acceleration (a) * distance (d)

Since vi = 0 and vf = 0, the equation simplifies to:

0 = 0 + 2 * a * d

Solving for acceleration (a), we have:

2 * a * d = 0

a = 0

Since the acceleration is zero, it means that the braking force needed to stop the lorry is also zero. This is likely not an accurate result as some force is required to stop the lorry. It's possible that additional information or calculations are needed to accurately estimate the braking force.

The braking force required to stop a 6371 kg lorry after spotting a hazard and applying the brakes is what the question is asking for. The lorry decelerates uniformly and comes to a stop 60 meters after the brakes are applied.

The following steps will guide you on how to calculate the braking force:

Step 1: Determine the mass of the lorry which is 6371 kg. This will be denoted as m.

Step 2: Determine the distance travelled by the lorry, which is 60 m.

Step 3: Determine the time taken by the lorry to stop. This can be done by using the formula for uniform deceleration, which is a = (v-u)/t where v is the final velocity, u is the initial velocity and a is the uniform deceleration. Since the lorry comes to a stop, its final velocity is zero and its initial velocity is unknown.

However, we can assume that the lorry was initially travelling at a constant speed before spotting the hazard. Therefore, we can assume that the initial velocity was equal to the average velocity of the lorry before the brakes were applied.

This can be calculated using the formula v = d/t where d is the distance travelled and t is the time taken. The average velocity can therefore be calculated as follows: v = d/t = 60 m/t

Step 4: Rearrange the formula for uniform deceleration, a = (v-u)/t, to find u which is the initial velocity. Since the lorry comes to a stop, we know that v = 0.

Therefore: u = v - at where a is the uniform deceleration and t is the time taken to stop which is also equal to the time taken for the lorry to travel the distance of 60 meters. Substituting for v, we get: u = - at

Step 5: Calculate the acceleration of the lorry using the formula a = (v-u)/t. Since the final velocity is zero, we get: a = -u/t = -(-at)/t = a The acceleration is negative since the lorry is decelerating.

Step 6: Calculate the braking force using the formula F = ma where F is the braking force and m is the mass of the lorry. Therefore: F = ma = (-ma) since a is negative = (-6371 kg) (a) Therefore, the braking force required to stop the lorry is -6371a N where a is the uniform deceleration calculated in Step 5.

Answer: elastic potential energy = 20.27 J

Explanation:

Given that the

Mass M = 0.470 kg

Height h = 4.40 m

Spring constant K = 85 N/m

The maximum elastic potential will be equal to the maximum kinetic energy experienced by the block.

But according to conservative of energy, the maximum kinetic energy is equal to the maximum potential energy experienced by the block of mass M.

That is

K .E = P.E = mgh

Where g = 9.8m/s^2

Substitutes all the parameters into the formula

K.E = 0.470 × 9.8 × 4.4

K.E = 20.27 J

Where K.E = maximum elastic potential energy stored in the spring during the motion of the blocks after the collision which is 20.27J.

The maximum potential energy stored in the spring during the motion of the blocks is 20.39 J.

The given parameters;

The extension of the spring is calculated as follows;

\(F =kx\\\\mg = kx\\\\x = \frac{mg}{k} \\\\x = \frac{0.47 \times 9.8}{85} \\\\x = 0.054 \ m\)

The maximum potential energy stored in the spring during the motion of the blocks is calculated as;

\(P.E = \frac{1}{2} kx^2 \ + mgh\\\\P.E = \frac{1}{2} (85)(0.054)^2 \ + \ (0.47)(9.8)(4.4)\\\\P.E = 20.39 \ J\)

Thus, the maximum potential energy stored in the spring during the motion of the blocks is 20.39 J.

Explanation: COMPOST BIN

WHAT IS A COMPOST BIN?

A compost bin is a container into which you place organic waste to turn into compost (organic material) over time.

Most compost bins are designed to hasten the decomposition of organic matter through proper aeration and moisture retention. With the proper combination of air and moisture, ideal conditions are produced for the activity of aerobic organisms responsible for the high temperatures that transform the organic materials into compost

Read on to find out how to start a compost bin, DIY compost bin ideas, and more tips for beginners.

The decomposition process will eventually take place over time in a compost "pile" or "heap," even without any housing to contain the matter. However, a compost bin is worth it because it helps speed up decomposition and keeps the area neat. Some bins are continuous, meaning you can keep adding waste to them, while others create batches of compost with a set mix of ingredients you add all at once. Depending on the style of compost bin you choose, bins can also have the advantage of making it harder for rats to get at your compost. This is true of the tumbler type, for example.

CHOOSING THE RIGHT BIN

Select the right bin for your composting needs. You can make an inexpensive compost container out of almost any container or material. Some ideas include:

Plastic storage container

Plastic bucket

Trash cans

Straw bales

Lumber

Branches harvested from the woods

Stone

Cinder blocks

Wire fencing

Ceramic (also popular for a kitchen countertop compost bin)

The best bin, however, is one you can easily turn or rotate consistently to control odors and make sure all the materials decompose. This is especially important for aerobic composting (more information below). A tumbler composting bin is pricey, but you can DIY one from barrels and sawhorses. You can turn compost with a rake or shovel in a non-rotating bin, it just takes more labor to do so.

The air currents across the continents would determine the distribution of the air.

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.
