What is the role of an electron in an atom

Answers

Answer 1

Answer:

Negative Charged Particle

Explanation:

Electrons are really small compared to everything else in the atom

Answer 2

Electrons give negative charge to the atom, and it balances out the positive charge given by the protons. That's the role of an electron!

Hope this helps!

An ecosystem is defined as

Answers

Answer:

Ecosystem is a geographic area where plants, animals, and other organisms, as well as weather and landscape, work together to form a bubble of life. It contains biotic or living, parts, as well as abiotic factors, or nonliving parts.

An ecosystem is defined as a location where a bubble of life is created by the interaction of plants, animals, and other species with the weather, topography, and other factors.

What is topography?

Topography is defined as the investigation of surface characteristics and shapes. In order to describe the shape of the terrain, topographic features are particular points, lines, and areas that correspond to local differential qualities of the surface of the terrain.

A self-sustaining unit of living creatures (plants, animals, and decomposers) and their non-living surroundings is called an ecosystem (air, water and soil). Examples: Aquatic plants and animals that dwell in pond water make up the aquatic portion of an ecosystem known as a pond. A biome is a group of associated ecosystems.

Thus, an ecosystem is defined as a location where a bubble of life is created by the interaction of plants, animals, and other species with the weather, topography, and other factors.

The initial water volume in this container was 10.0 mL. When the key was submerged, 3 volumes of displaced water were collected: 0.7 mL, 0.8 mL, and 0.9 mL. What is the volume of the key?
How did you find the volume?

Answers

The volume of the key is 0.8 mL.

Volume of objects using sinker method

An object that floats on water will displace its own volume. In the same vein, an object that sinks in water will displace its own volume.

Thus, in order to find the volume of an object that sinks in water, measure the volume of water that it displaces.

In this case, the water displaced by the key was measured 3 times. The average of the 3 readings will give the volume of the key.

Volume of the key = 0.7 + 0.8 + 0.9/3 = 0.8 mL

ILL GIVE BRANLIEST TO THE BEST ANSWER THATS A PARAGRAPH AND GIVES 2 REASONS WHY ITS EITHER PAT OR TRACY!!

Answers

Answer:

Pat is most likely to have made the hydrofluoric acid.

Explanation:

How is hydrofluoric acid made?

It is manufactured by heating purified fluorspar (calcium fluoride) with concentrated sulfuric acid to produce the gas, which is then condensed by cooling or dissolving in water. ... The acid hydrolysis of fluorite-containing minerals generates an impure gas stream consisting of sulfur dioxide, water and HF.

that's all I got sorry

The argument regarding hydrofluoric acid.

The scientific community has made an argument that addresses the to questions of the suspect how likely it's for the formation of the hydrofluoric acid.

The statement is given as per the claims that support them. the answer. Hydrofluoric acid is an solution in the hydrogen fluoride in water and they are colorless.

Thus answer is Pat has made hydrofluoric acid.

As per the table, the police have to identify the suspect that has made the acid and was ordered from a local chemical supply company that makes the acid. The work of pat as a sculptor is to make sulphuric acid and calcium fluoride.The substance is a string, is a string, and is colorless and a liquid at room temperature. Hence pat is responsible for making s er the modeling tool sheet.

When the speed of the bottle is 2 m/s, the KE is kg m2/s2. When the speed of the bottle is 3 m/s, the KE is kg m2/s2. When the speed of the bottle is 4 m/s, the KE is kg m2/s2. When the speed of the bottle is 5 m/s, the KE is kg m2/s2. When the speed of the bottle is 6 m/s, the KE is kg m2/s2.
instructions
In this part of the experiment, you will be changing the speed of the bottle by dropping it from different heights. You will use the same mass, 0.250 kg, for each trial, so record this mass in Table B for each velocity. Then, calculate the expected kinetic energy (KE) at each velocity. Use the formula KE = mv2,
where m is the mass and v is the speed. Record your calculations in Table B of your Student Guide.

Answers

Answer:

Based on the given instructions, you need to calculate the expected kinetic energy (KE) at each velocity using the formula KE = mv^2, where m is the mass and v is the speed. The mass is given as 0.250 kg.

Table B: Calculation of Kinetic Energy (KE)

Speed (m/s)Mass (kg)KE (kg m^2/s^2)20.2500.50030.2500.75040.2501.00050.2501.25060.2501.500

To calculate the kinetic energy at each velocity, multiply the mass (0.250 kg) by the square of the velocity.

For example, when the speed of the bottle is 2 m/s: KE = (0.250 kg) * (2 m/s)^2 = 0.250 kg * 4 m^2/s^2 = 1.000 kg m^2/s^2

Perform similar calculations for the other velocities and record the results in Table B.

Answer:

Explanation:mass of the bottle in each case is M = 0.250 kg

now as per given speeds we can use the formula of kinetic energy to find it

1) when speed is 2 m/s
