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
Explanation:
Given that,
Initial volume = 60dm³
Initial pressure = 30 kPa
We need to find the new volume when pressure changes to 40 kPa (say).
We know that the mathematical relation between volume and pressure is given by :
Put all the values,
So, when pressure of the gas increases, its volume get decreased.
Answer:
Lydia made a marginal decision because she is trying to save for her collage by spending less, she will have some money left over after paying for her necessary to go to her college tuition.
Explanation:
She saved part of it for her college tuition and spent the remainder for the prom dress, car insurance, and birthday gift.
