B. Aluminum is possibly correct
1. Magnetic properties of a substance depends on the structure of its valence electrons. It has something to do with orbitals so I suggest you study about molecular geometry of a compound/substance firstIt's the way a substance's atoms fit together, being pulled and pushed from all sides equally. exists in metallic bonds <span>if a substance is said to be magnetic, it is simply attracted by a magnet. if it is paramagnetic, it is repelled by a magnet.
2.</span>The magnetic field will be perpendicular to the electric field and vice versa<span>
An electric field is the area which surrounds an electric charge within which it is capable of exerting a perceptible force on another electric charge.
A magnetic field is the area of force surrounding a magnetic pole, or a current flowing through a conductor, in which there is a magnetic flux. A magnetic field can be produced when an electric current is passed through an electric circuit wound in a helix or solenoid.
The relationship that exists between an electric field and a magnetic field is one of electromagnetic interaction as a consequence of associating elementary particles.
The electrostatic force between charged particles is an example of this relationship.</span>
Calculate its average speed in meters per second
Answer:
5.77 m/s
Explanation:
Speed= Distance/Time
Distance= 40+ half of 40= 40+20= 60 m
Time= 8.8+1.6=10.4 s
Average speed= 60/10.4=5.769230769 m/s
Approximately, the average speed is 5.77 m/s
