near the north and south poles of the magnet
Explanation:
Magnetic fields around a permanent magnet is strongest near the north and south poles of the magnet.
Magnetic fields are the region of space around a magnet where magnetic effects are felt.
- This is as a result of a force field that surrounds the magnet.
- Magnetic fields are strongest within the magnet.
- Also, externally, they are strongest at the poles of a magnet.
- Around the poles, magnetic lines of force leaves and enters a magnet.

Answer:
Explanation:
Frequency is oscillations per second.
So we have to find the Number of seconds she paced.
2 minutes = 2 X 60
= 120 seconds
Therefore,
Her frequency = 10 / 120
= 1/12 Hertz
Answer:
Explanation:
A )
The ball floats with half of it exposed above the water level . So it must have density half that of water . In other words its density must have been 500 kg / m³
B )
Tension in the ball will be equal to net force acting on the ball
Net force on the ball = buoyant force - weight .
4/3 x π x .21³ x 10⁻⁶ x 9.8 ( 1000 - 893 )
= 40.65 x 10⁻⁶ N .
C )Tension in the 3 rd ball will be equal to net force acting on the ball
Net force on the ball = weight - buoyant force
= 4/3 x π x .21³ x 10⁻⁶ x 9.8 ( 1320 - 1000 )
= 121.6 x 10⁻⁶ N .
