Answer:10

Explanation:

In the context of the Moon model, the fraction of the Moon that was always lit up by the light is half, or 1/2.

The explanation for this is that the Moon model discussed previously most likely depicts the Moon's phases as seen from Earth. The phases of the moon are caused by distinct areas of the lit side of the moon that are visible from Earth at various times during its orbit.

The Sun always illuminates half of the Moon's surface, leaving the other side in darkness. From Earth, we can only see the bright portion; the unlit portion is invisible. Different phases result from variations in the visible fraction of the lighted half of the Moon as it revolves around the Earth.

Therefore,  the fraction of the Moon that was always lit up by the light is half, or 1/2.

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).

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.

5. red giants

Explanation:

Main sequence stars have a Morgan-Keenan luminosity class labeled V. red giant and supergiant stars (luminosity classes I through III) occupy the region above the main sequence. They have low surface temperatures and high luminosities which, according to the Stefan-Boltzmann law, means they also have large radii. White dwarf stars are much hotter than Red Supergiants 15. List the color of the stars from hottest to coldest: Blue, White, Yellow, Orange, Red 16. The hottest stars are the blue stars. A star appears blue once its surface temperature gets above 10,000 Kelvin, or so, a star will appear blue to our eyes. The lowest temperature stars are red while the hottest stars are blue. Astronomers are able to measure the temperatures of the surfaces of stars by comparing their spectra to the spectrum of a black body. Most stars, including the sun, are "main sequence stars," fueled by nuclear fusion converting hydrogen into helium. ...

As stars begin to die, they become giants and supergiants (above the main sequence).

No, I don't agree with the friend.

I don't agree because the energy doesn't just "disappear it's converted to kinetic energy. due to the friction some of the energy in the system is converted to heat energy making it look like it "disappeared".

Energy can't be created nor destroyed so it definitely can't just disappear though it can be converted or transformed.

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.

Answer:

v = sqrt((10/7)gh)

Explanation:

The given equation is:

mgh = (1/2)mv^2 + (1/5)mv^2

To solve for v, we can start by simplifying the right side of the equation:

mgh = (7/10)mv^2

Dividing both sides by (7/10)mv^2, we get:

mgh / (7/10)mv^2 = 1

Multiplying both sides by (10/7)m/gh, we get:

v^2 = (10/7)gh

Taking the square root of both sides, we get:

v = sqrt((10/7)gh)

Therefore, the solution for v in terms of m, g, h is:

v = sqrt((10/7)gh)
