can a larger object orbit a smaller one? why or why not? can planets orbit moons? i need the answer quickly please help me

A larger object does orbit a smaller one

Explanation:

While it's true that both bodies make ellipses around the center of mass, from the frame of mass 1 the other mass is orbiting in ellipses around mass 1 as well. ... So if you have a very heavy small object and a very light large object it is possible for a "big" object to orbit a "smaller" object.

a solenoid is created by wrapping a l = 90 m long wire around a hollow tube of diameter d = 4.5 cm.   the wire diameter is d = 0.9 mm.   the solenoid wire is then connected to a power supply so that a current of i = 9 a flows through the wire.

randomized variablesl = 90 m

d = 4.5 cm

d = 0.9 mm

i = 9 a                                          

write an expression for the number of turns, n, in the solenoid. you do not need to take into account the diameter of the wire in this calculation.

calculate the number of turns, n, in the solenoid.

write an expression for the length of the solenoid (l2) in terms of the diameter of the hollow tube d.

calculate the length of the solenoid (l2)   in meters.

calculate the magnitude of the magnetic field at the center of the solenoid in teslas.
