Answer:
Explanation:
The funny-looking circle is a hint but iii confirms we are talking about Eartth's magnetic field here :)
i. A is North Pole while H is the magnetic North Pole. D is the equator while C is the magnetic equator.
ii. I, the tilt angle, is about 11 degrees.
iii. A freely suspended magnet inclines towards HF or AG because it always points towards North/South.
She’ll need all objects to make an electrical current inside a magnetic field
(1) First compute the linear speed of the mass. If it completes 1 revolution in 0.5 seconds, then the mass traverses a distance of 2<em>π</em> (1.0 m) ≈ 2<em>π</em> m (the circumference of the circular path), so that its speed is
<em>v</em> = (1/0.5 rev/s) • (2<em>π</em> m/rev) = 4<em>π</em> m/s ≈ 12.57 m/s
Then the centripetal acceleration <em>a</em> is
<em>a</em> = <em>v</em>² / (1.0 m) = 16<em>π</em>² m/s² ≈ 160 m/s²
(where <em>r</em> is the path's radius).
(2) By Newton's second law, the tension in the string is <em>T</em> such that
<em>T</em> = (0.50 kg) <em>a</em> = 8<em>π</em>² N ≈ 79 N
Answer:
i think maybe because it has more than 6 or 5 parts.
