Freezing is a way to make magnets from ferromagnetic substance.
What is Curie temperature?Curie point, also known as Curie Temperature, is the temperature at which the magnetic characteristics of some magnetic materials abruptly change. Remnant magnetism manifests in rocks and minerals below the Curie point, which for magnetite, a common magnetic mineral, is approximately 570 °C (1,060 °F).
In some magnetic materials, atoms that act as small magnets spontaneously align themselves below the Curie point, which for iron is 770 °C (1,418 °F). Because the atomic magnets in each microscopic region (domain) of ferromagnetic materials, such as pure iron, are aligned in the same direction, their magnetic fields reinforce one another.

A glass rod is rubbed briefly with silk and the rod becomes able to attract and lift a number of small pieces of paper. If the rod is rubbed with silk for a longer period of time, explain what will happen and why.
QUICKLY PLEASE!
Answer:
it will have a stronger attraction force
Explanation:
If the rod is rubbed with silk for a longer period of time, then it attract large number of small pieces of paper.
When A glass rod is rubbed briefly with silk, then glass rod is heated because of rod become positively charged. That positively charged glass rod attracts the uncharged pieces of paper because some of the electrons present in the paper accumulate at the end near the rod.Learn more:

what are two roles of bacteria in a nitrogen cycle
Answer:Nitrogen-fixing bacteria convert free nitrogen gas into nitrogen compounds. ... Bacterias that are decomposers recycle nitrogen compounds in the soil by breaking down animal wastes and dead plants and animals. 3. Other bacteria break down nitrogen compounds and release free nitrogen back into the air.
Explanation:
"The nitrogen fixing and bacteria of decay" is the two major role of bacteria in nitrogen cycle."
What is nitrogen fixing?Nitrogen fixing can be define as the process in which It is possible to see nitrogen converting to nitrate.
What is bacteria of decay?Bacteria of decay can be define as the process in which it is possible to see nitrogen waste converting to ammonia.
What is nitrogen?Nitrogen can be referred as element which is kept in boron family in the periodic table.

What are the characteristics of bones? (list 7)
What role do joints play?
What are the two types of joints?
What are ligaments?
Answer:
1) The human skeleton performs six major functions: support, movement, protection, production of blood cells, storage of minerals, and endocrine regulation. protection of internal organs
2) Joints are where two bones meet. They make the skeleton flexible — without them, movement would be impossible. Joints allow our bodies to move in many ways.
3)A joint is a point where two or more bones meet. There are three main types of joints; Fibrous (immovable), Cartilaginous (partially moveable) and the Synovial (freely moveable) joint
4)A ligament is a fibrous connective tissue which attaches bone to bone, and usually serves to hold structures together and keep them stable.

I need help with question ii) Calculate the speed of these radio waves.
I don't know if I started it right.... I need help plss!!!
Answer:
Speed = Wavelength x Wave Frequency. In this equation, wavelength is measured in meters and frequency is measured in hertz (Hz), or number of waves per second. Therefore, wave speed is given in meters per second, which is the SI unit for speed.
