(a)
The poles in the magnet.
(a)
Explanation of Solution
Introduction:
A magnet is a substance which attracts other magnetic materials. A magnet has two poles-North pole and south pole. Magnetic field lines emerge from north pole and enter in south pole.
The poles are always at the ends of a magnet. In the given magnet, 2 and 4 represent poles. The magnetic field strength is maximum near the poles and are represented by crowding of the field lines near the ends of a magnet.
(b)
The north pole of the magnet.

The poles are always at the ends of a magnet. Magnetic field lines emerge from north pole and enter in south pole. So, 2 represents north pole because field lines are emerging from that end.

- Consider a rubber rod that has been rubbed with fur to give the rod a net negative charge, and a glass rod that has been rubbed with silk to give it a net positive charge. After being charged by contact by the fur and silk...? a. Both rods have less mass b. the rubber rod has more mass and the glass rod has less mass c. both rods have more mass d. the masses of both rods are unchanged e. the rubber rod has less mass and the glass rod has mroe massarrow_forward8) 9)arrow_forward10) 11) 12) 13) 14) 15)arrow_forward
- Mick and Rick are twins born on Earth in the year 2175. Rick grows up to be an Earth-bound robotics technician while Mick becomes an intergalactic astronaut. Mick leaves the Earth on his first space mission in the year 2200 and travels, according to his clock, for 10 years at a speed of 0.75c. Unfortunately, at this point in his journey, the structure of his ship undergoes mechanical breakdown and the ship explodes. How old is Rick when his brother dies?arrow_forwardHi, I have canceled, why did you charge me again?arrow_forwardNo chatgpt pls will upvotearrow_forward
