Answer:
-4.72005 m/s
0 m/s
Explanation:
Displacement = 5220 km
Time = 12.8 days
The average velocity is given by
The average for the return flight is -4.72005 m/s
When the total displacement is divided by the total time of a journey then we get the average velocity.
Displacement is the minimum distance between the initial and final points of the journey.
Here, the displacement of the whole episode is 0 as the initial and final point is zero.
Hence, the average velocity for the whole episode is 0 m/s
Answer:
16.042336 Am²
27.2719712 Nm
Explanation:
Dipole moment association with iron atom
L = Length of bar = 6.5 cm
A = Area of bar = 1 cm²
= Avogadro constant =
= Density of iron = 7.9 g/cm³
M = Molar mass = 55.9 g/mol
B = Magnetic field = 1.7 T
Number of atoms is given by
Dipole moment is given by
The dipole moment of the bar is 16.042336 Am²
Torque is given by
The torque exerted to hold this magnet perpendicular to an external field is 27.2719712 Nm
