Answer:
Recycling centres use magnetic separation often to separate components from recycling, isolate metals, and purify ores. Overhead magnets, magnetic pulleys, and the magnetic drums were the methods used in the recycling industry. Magnetic separation is also useful in mining iron as it is attracted to a magnet.

What is the strongest reason Elbridge Gerry gave for not signing the Constitution?
Answer:
He antagonized nearly everyone by his inconsistency and, according to a colleague, "objected to everything he did not propose." At first an advocate of a strong central government, Gerry ultimately rejected and refused to sign the Constitution because it lacked a bill of rights and because he deemed it a threat to republicanism

An ionic bond involves the
Answer: Ionic bonding is a type of chemical bonding that involves the electrostatic attraction between oppositely charged ions, or between two atoms with sharply different electronegativities, and is the primary interaction occurring in ionic compounds.
Explanation:
Use this picture to explain that an electrically charged object can attract an uncharged object without any contact. Your answer should be at least three sentences long.
a balloon hanging from a string with small pieces of paper stuck to the bottom of it, with a few pieces on the ground
Answer:
Charges: positive and negative
Explanation:
When we put a charged object near an uncharged object, it produces opposite charges in the near end of the uncharged object by electric induction. In the figure, we can see that the ballon has charges which produces opposite charges in the paper which is uncharged

Use at least three complete sentences to explain how global wind patterns such as the prevailing westerlies in the northern hemisphere would be impacted if the rotation of Earth stops.(5 points)
Answer:
If the Earth did not spin on its axis, the atmosphere would only circulate between the poles and the equator. And if this happens, the very same thing is bound to happen over again. That is, the atmosphere would only circulate in a back-and-forth pattern between the poles and the equator over and over.
The force that holds two atoms together is called a(n) _______

The force that holds two atoms together is called a chemical bond.
What is a chemical bondA chemical bond is a force of attraction that holds two or more atoms together to form a stable molecule or compound. Atoms consist of a positively charged nucleus containing protons and neutrons, surrounded by negatively charged electrons. In order to achieve a stable electronic configuration, atoms can undergo chemical bonding to fill their outermost electron shells.
Chemical bonds play a vital role in determining the physical and chemical properties of substances. The strength and type of bond between atoms influence factors such as boiling points, melting points, solubility, and reactivity. Understanding chemical bonds helps explain how different substances interact and form new compounds.

3. The cities listed below, from Chicago to Pittsburgh, lie in a roughly straight west to east line. Data on temperature, barometric pressure, and sky conditions for each city are shown in the table below. Use the data to explain what types of air masses are present and/or moving among these cities and how this accounts for the weather. What will Pittsburgh’s weather be like within the next 24 to 48 hours?
City Temp (oF) Pressure (in.) Conditions
Chicago, IL 73 29.94 rising Clear
Indianapolis, IN 75 29.93 falling Partly cloudy
Columbus, OH 78 28.20 falling Light rain
Pittsburgh, PA 74 29.90 steady Mostly sunny
Answer:
For the next 24-48 hours, Pittsburgh will see light rain. The storm is moving west-to-east toward Pittsburgh, as indicated by a drop in pressure over western cities. Precipitation is usually associated with low pressure systems.
What is weather forecasting?Weather forecasting is the application of science and technology to predict atmospheric conditions at a particular place and time.People have been trying to predict the weather informally for thousands of years, but have been doing so formally since the 19th century.Weather forecasting is the application of science and technology to predict atmospheric conditions for a particular place and time.Humans have tried to predict the weather informally for thousands of years, but only formally since the 19th century due to incomplete understanding of the ocean, measurement errors in initial conditions, atmosphere and related processes.Weather warnings are important forecasts that protect lives and property.Forecasts based on temperature and precipitation are important for agriculture and therefore for commodity market traders. Temperature forecasts are used by utility companies to forecast demand for the next few days.Many people use the daily weather forecast to decide what to wear on any given day.To learn more about weather forecasting, refer to:

how does energy transfer through a system? Is all the energy conserved?
Answer:
Explanation:
The total change of energy in any system is always equal to the total energy transferred into or out of the system. This is called conservation of energy. ... Energy can also be transferred from place to place by electric currents. Heating is another process for transferring energy.

How can a charged balloon attract a wall without any contact?
The positive charges of the uncharged wall move to the outside.
The wall changes shape and the positive charges move to the inside.
The negatively charged balloon repels and moves away from the wall.
A positive charge in the balloon attracts the negative charges in the wall.
Answer:
Because it is charged with the opposite type of energy to the wall.
Answer: A
Explanation: The positive charges of the uncharged wall move to the outside.
