Why earth magnetism not attract iron?

Will Upvote! If the mass of two objects increases, the force of gravity between them increases decreases remains the same could increase or decrease, depending on the shape of the objects

A uniform, solid metal disk of mass 6.00 kg and diameter 29.0 cm hangs in a horizontal plane, supported at its center by a vertical metal wire. You find that it requires a horizontal force of 4.28 N tangent to the rim of the disk to turn it by 3.

You slide a box of books at constant speed up a 30° ramp, applying a force of 200 n directed up the slope. the coefficient of sliding friction is 0.18.

Two trains leave the same station at the same time. The first train travels north at 60 mph. The second train travels west at 45 mph. Find how fast the distance between the trains is changing two hours after the trains have left.

If the room radius is 4.5 m, and the rotation frequency is 0.8 revolutions per second when the floor drops out, what is the minimum coefficient of static friction so that the people will not slip down?
