Answer:
<em>x=6.39 m</em>
Explanation:
<u>Rectangular Components of a Vector</u>
Vectors can be expressed in several forms, including the magnitude-angle form, and the rectangular-coordinates form.
If the magnitude r and angle β are given, we can find the rectangular coordinates (x,y) as follows:
The vector of the question has a magnitude of r=9.55 m and an angle β=-48°. The x-component is:
Using a digital calculator:
x=6.39 m
Answer:
Metal paper clips do not attract or repel each other. When an electromagnet is placed nearby, the paper clips can be observed to move toward it. Which statement describes this phenomenon?
- Magnetic domains within the paper clips align with the magnetic field.
An electromagnet is built using a 9-volt battery with conducting wire connected to a switch and coiled around an iron nail. A pile of metal paper clips is moved close to the iron nail, yet no attraction is apparent between the electromagnet and the paper clips. What is the most likely conclusion to explain this result?
- The switch is turned off.
An experiment modeled the interaction between magnetic force and the change of energy of an object influenced by the magnetic force. The experiment’s researchers observed that the metal wheels of a small car turned as they experienced the force exerted by a magnetic field, drawing the car closer to the magnet. What energy is being gained by the car?
- Kinetic Energy
Which statement about the current and magnetic field correctly describes this figure as well as all electromagnets?
- The current generates and is perpendicular to the magnetic field.
Domains are the regions in a material in which the magnetic fields of many of the atoms are aligned facing the same direction. What is the relationship between the electrical current and the alignment of atoms responding to the current?
- As current increases, the alignment becomes more organized.
