They are not parallel like latitude lines. They meet at the poles, but latitude lines never meet
Answer:
v = 2 m/s
Explanation:
First, we find the angular velocity of the girl by using the following formula:
Now, for the average velocity of the girl we can use the following formula:
where,
r = radius = 200 m
therefore,
<u>v = 2 m/s</u>
The cells that circulate in the bloodstream are generally divided into three types, white blood cells.
Answer:
μ =5.40 A-m²
Explanation:
The components of the net magnetic field are the magnetic field of the dipole and the magnetic field of Earth, then from the right triangle, the deflection angle is computed by
tan θ = Bdipole / Bearth ⇒ Bdipole = Bearth* tan θ
Bdipole = 2e-5 T*tan 70° = 5.49e-5 T
The magnetic field at the location of the compass due to the dipole has a magnitude
Bdipole = (μ₀/4π)(2μ/r³) ⇒ μ = Bdipole r³ / 2(μ₀/4π)
μ = (5.49e-5 T)(0.27m)³ / 2(1 × 10−7 T m² /(C m/s)) = 5.40 A-m²
