Answer:

The distance between two charges i.e electrons with F= 1.5N is given by\(r=1.232*10^{-14}\)

Explanation:

To find the distance between 2 electrons, we'll use the Coulombs Law

Coulombs Law states the the Force of attraction or repulsion between any two chargers is directly proportional to the product of both charges and inversely proportional to the square of the distance between them.

Coulombs Law states that (when q₁ = q₂) :

\(F=k\frac{q^2}{r^2}\)

where

\(k=8.9*10^9 Nm^2C^-2\)

\(q=1.6*10^{-19} C\)

\(F = 1.5 N\)

Find r

\(r^2=k\frac{q^2}{F}\)

Substitute the values

\(r^2=\frac{(8.9*10^9)(1.6*10^{-19})^2}{1.5}\\r^2= 1.5189*10^{-28}\\r=1.232*10^{-14}\)

Explanation:

The distinctive characteristic of a topographic map is the use of elevation contour lines to show the shape of the Earth's surface. Elevation contours are imaginary lines connecting points having the same elevation on the surface of the land above or below a reference surface, which is usually mean sea level.

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).

Euglena, amoeba, paramecium, and volvox are all protists, which are a diverse group of single-celled organisms. All four protists are unicellular and can be found in aquatic environments. One similarity between these protists is that they all have the ability to move, whether it be through cilia, flagella, or pseudopodia. However, there are also differences between these protists. Euglena has both chloroplasts and a flagellum, which allows it to carry out photosynthesis and move through water. Amoeba, on the other hand, moves through the use of pseudopodia and can change its shape. Paramecium is a ciliate and uses its cilia to move and capture food. Volvox is a colonial organism, made up of many individual cells that work together to move and reproduce. Overall, these four protists have different characteristics and abilities, but all are considered protists and share certain similarities.

To find the volume of the block, subtract the initial water volume from the final water volume, convert the change in water volume to cubic centimeters, and consider it as the volume of the block.

To find the volume of the block using the measurements provided.

1. Calculate the change in water volume:

The initial water volume is given as 62.3 mL, and the final water volume is given as 89.5 mL. To determine the change in water volume, we subtract the initial volume from the final volume: 89.5 mL - 62.3 mL = 27.2 mL. This value represents the increase in water volume caused by placing the block in the graduated cylinder.

2. Convert the change in water volume to cubic centimeters:

Since 1 mL is equivalent to 1 cubic centimeter (cc), we can directly convert the change in water volume from milliliters to cubic centimeters. In this case, the change in water volume is 27.2 mL, which is also equal to 27.2 cc.

3. Determine the volume of the block:

When the block is placed in the graduated cylinder, it displaces some amount of water, resulting in an increase in water volume. By measuring this increase in volume, we can determine the volume of the block itself. In this case, the change in water volume of 27.2 cc represents the volume of the block.

By following these steps, we can find the volume of the block based on the provided measurements.

Therefore, By deducting the initial water volume from the final water volume and converting the difference in water volume to cubic centimeters, the block's volume can be calculated. the volume of the block is 27.2 cc.

The group which was designed to study Saturn is C. Voyager 1, Huygens, and Cassini. It was a collaborative mission involving NASA, ASI, and ESA.

The trio of Voyager 1, Huygens, and Cassini embarked on groundbreaking missions, collectively enhancing our understanding of Saturn and its diverse moons. Launched by NASA in 1977, Voyager 1 ventured into the outer solar system, conducting close flybys of Jupiter and Saturn, capturing detailed imagery and valuable scientific data.

Huygens, a constituent of the collaborative Cassini-Huygens mission involving NASA, ESA, and ASI, made a historic touchdown on Saturn's moon Titan in 2005. It meticulously examined Titan's atmosphere and surface, yielding unprecedented insights.

Meanwhile, the Cassini spacecraft, another integral part of the Cassini-Huygens mission, meticulously orbited Saturn for more than 13 years. Cassini extensively studied Saturn's rings, atmosphere, and numerous moons, unraveling captivating discoveries such as new moons and tempestuous storms.

The Cassini mission culminated with a planned atmospheric entry into Saturn. These missions collectively revolutionized our knowledge of Saturn, its enigmatic rings, and its captivating moons.
