1) The moon is not traveling in a perfect circle therefore the force is not inward. However, what object is applying the net force on the moon? 2) Does the Moon apply a force to the Earth? Explain

3) Does the Earth apply a force to the Moon? Explain

4) The force between two masses is 2 N. If the distance between the two masses is tripled, what is the new force between the masses?

5) The force between two masses is 2 N. If the mass of one of the masses is tripled, what is the new force between the masses?

Please help I am not comphrending it at all.

1) The gravity on the moon is 1.62 m/s² which means the moon rotates with force using gravity.

2) The Moon's surface gravity is about 1/6th as powerful or about 1.6 meters per second per second. The Moon's surface gravity is weaker because it is far less massive than Earth. A body's surface gravity is proportional to its mass, but inversely proportional to the square of its radius.

3) The moon pulls on the Earth with the exact same magnitude of force that the Earth pulls on the moon since it is the same interaction. But wouldn't this also make the Earth move in a circle? Yup. Essentially, it does.

4) The mass of one object is doubled

If the mass of one of the objects is doubled, then the force of gravity between them is doubled. ... Since gravitational force is inversely proportional to the square of the separation distance between the two interacting objects, more separation distance will result in weaker gravitational forces.

Answer from: Quest

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.
