<h3><u>Answer;</u></h3>
<em>Only some metals are attracted by magnets; these metals are called ferromagnetic.</em>
<h3><u>Explanation;</u></h3>
- <u><em>Magnets</em></u> are those materials that have the ability of producing magnetic field. Magnets attracts materials called magnetic materials and have no effect on non magnetic materials such as wood.
- <em><u>Magnetic materials </u></em>are materials that are attracted by a magnet, these includes some metal such as iron and steel. However some metals are non-magnetic materials, these include, gold, silver, and copper among others,
- Therefore, it would be appropriate to say that<em> </em><em><u>only some metals are attracted by magnets; these metals are called ferromagnetic.</u></em>

Answer:
D potential energy at the top of the stairs, kinetic energy as she walks down
Explanation:
The potential energy of a body is the energy due to the position of the body.
At the top of the stair case, the student is at a significant height.
Kinetic energy is the energy due to the motion of the body.
As the student descends, the potential energy is changed to kinetic energy.
To find the potential energy;
P.E = mgH
m is the mass
g is the acceleration due to gravity
H is the height of the body
To find the kinetic energy;
K.E = 
m v²
m is the mass
v is the velocity
1.) Electrons go back into like a lower energy level then would be release a thing called a photon light.
2.) I'm not sure on the correct numbers exactly but if I remember correctly around 70-80 percent is nitrogen, around 20-25 is percent oxygen, 0.9 percent is argon, and 0.1 percent other gases.
3.) Glass is made from sand at least that's one popular element of making sand. one gathered, they are put into a high temperature and would soon make glass coming out of it within time.
